SUMMARY:Scotland’s Greatest Ice Age
DESCRIPTION:Talk by Emeritus Professor Ian Fairchild\, University of Birmingham \nAbstract:\nThe Port Askaig Formation were the first Precambrian rocks interpreted as glacial in origin\, anywhere in the world. Now we know that Neoproterozoic glaciation was global in distribution. The exposures of the Port Askaig Formation are also the best permanent exposures of glacigenic deposits of any age in the British Isles and have attracted much international interest. Over a decade of study by an interdisciplinary team have led to many new insights that will be presented in a Memoir of the Geological Society of London. There is an informal proposal that the base of the Cryogenian geological System should be located here on the Garvellach Islands of western Scotland.  \nIan Fairchild’s contributions to Neoproterozoic geology have focused mainly on Svalbard and Greenland\, as well as Scotland. In relation to the Port Askaig rocks he has sought to understand the association of dolomite with glacigenic facies and the significance of the glacial record both on the Garvellachs and the Isle of Islay. \nView This Talk In The Members’ Section.

SUMMARY:Unveiling the geology of Mars with robotic explorers
DESCRIPTION:Talk by Dr Joe McNeil\, Natural History Museum\, London. \nAbstract:\nBefore the first observations of Mars by orbiting spacecraft in the 1970s\, it was widely thought that the red planet resembled Earth’s Moon in its geology. However\, decades of robotic exploration by orbiters\, landers\, and rovers alike have radically reshaped our understanding\, revealing Mars’ unique and complex geological history. Abundant evidence of past liquid water on its surface reveal processes both familiar from Earth and others that are entirely unique to Mars. In this talk\, we will cover an overview of Mars’ geology\, discuss how geological investigations of Mars are conducted from orbital and landed spacecraft\, and explore the geological mysteries of Oxia Planum\, the future landing site of the European Space Agency’s ‘Rosalind Franklin’ ExoMars Rover (launching in 2028). \nView This Talk In The Members’ Section. \n\nPerseverance examines martian geology

SUMMARY:Modelling the Atmospheres of Tidally-locked Terrestrial Exoplanets
DESCRIPTION:Talk by Dr. Andrew Rushby\, Birkbeck College\, University of London unfortunately had to be cancelled. We hope to reschedule the talk and include it in our 2025 programme. \nAbstract\nThe climates of terrestrial planets are affected by their host star\, the properties of their atmospheres\, as well as any land\, ocean\, and icy surfaces\, in predictable but also complex ways. I will provide a short introduction to the novel climatologies of tidally-locked (synchronously-rotating) planets in the orbit of small\, cool M-Dwarf stars\, highlighting recent ensemble and climate model intercomparison studies have been used to uncover some of the effects of the complex\, ‘non-Earth-like’ rotational regimes of these worlds\, which are likely common in our galaxy\, on their possible climates and habitability by presenting some results from my recent work\, as well as that of my students\, collaborators\, andcolleagues working in this area. \nIf time allows\, I will also discuss the NASA ‘Research Coordination Network’ (RCN) model (of which NExSS was the first) and the means by which the astrobiology research and funding landscape within NASA\, and beyond\, is evolving to meet the needs of interdisciplinary scientists working in the field to leverage upcoming NASA\, ESA\, JAXA etc. missions\, analogue studies\, and observational platforms. \nBio – Dr Andrew Rushby is a Lecturer in Astrobiology and Programme Director of the MSc. Astrobiology programme in the School of Natural Sciences at Birkbeck\, University of London. \n\nSnowball Earth

SUMMARY:Painting with Stone: Materials\, Methods and Traditions in Pietre Dure
DESCRIPTION:Talk by Dr. Ruth Siddall (University College London) \nAbstract:\nThe talk will introduce the history\, techniques and materials used in the decorative art of pietre dure (hard stone work). Almost every stately home and museum has a table-top or other object decorated with pietre dure and yet the craftmanship and materiality of the technique has been one of the most disregarded topics of study within the decorative arts. The technique of making patterns with coloured stones began in Antiquity and then found a renaissance in 15th Century Europe and was used equally for adorning large objects of furniture and small items such as stuff boxes and jewellery. The technique remained popular until the 19th Century in Europe and continues to be used in architecture and the decorative arts in Asia and particularly in India. The choice of stones used often has a specific connection to the workshops and therefore a knowledge of decorative stones used is essential for assigning a provenance to works made using the pietre dure technique. \nView This Talk In The Members’ Section.

SUMMARY:Spying on open vent volcanoes from ground\, air and space
DESCRIPTION:Talk by Dr. Emma Nicholson (Liu)\, University College London \nAbstract: \n“Open vent” volcanoes are persistently active and maintain an unbroken connection between shallow magma reservoirs and the atmosphere. These volcanoes are true natural laboratories\, providing an unparalleled window into the subsurface physical and chemical processes that control volcanic activity. Open vent volcanoes sustain large volcanic gas emissions and are therefore the “chimney pipes” of our planet\, responsible for shaping the Earth’s atmosphere over geological time and impacting regional air and water quality on human timescales. Lava lakes are rare end-members in the expressions of open vent volcanism and can remain stable for years to decades. Yet\, recent events at Kilauea (Hawaii)\, Ambrym (Vanuatu) and Nyiragongo (DRC) have emphasized how rapidly these lakes can drain to feed voluminous flank eruptions\, posing substantial environmental and societal hazards. I will review some of the recent advances and outstanding questions in our understanding of the mechanisms and impacts of open vent volcanic activity. In particular\, I will focus on how remote sensing observations—from the ground\, air and space—combined with studies of erupted volcanic rocks are providing new perspectives on the long-term eruptive behaviour of open vent volcanoes. This talk will draw on new insights from a National Geographic expedition to one of the most remote active volcanoes on Earth – Mt Michael\, located in the South Sandwich Islands at the gateway to the Southern Ocean. \nView This Talk In The Members’ Section.

SUMMARY:Identification and implications of the London Clay Formation divisions from an engineering perspective
DESCRIPTION:Dr. Jamie Standing\, Imperial College London \nAbstract: Historically\, engineers viewed the London Clay (LC) Formation as uniform\, homogeneous and rather uninteresting.  Chris King’s seminal work provided a much deeper insight into the characteristics of the LC and how it can be split into divisions\, based on the depositional history of the formation and the microfauna present.  LC water content profiles were compiled from continuous cores as part of an investigation into variations in tunnelling-induced settlements across St James’s Park\, allowing distinct zones to be identified.  These were found to coincide exactly with the divisions identified by Chris King almost twenty years earlier.  Water content profiles can be developed as part of a ground investigation and used to help establish the boundaries between King’s divisions.  Based on two further water content profiles from Hyde Park and St John’s Wood a new methodology for locating the boundaries of the divisions\, involving a trend-line for sub-Division A3\, is proposed and tested\, relevant to conditions in central London.  In developing the method\, significant differences in the elevation of the divisions between the three sites is observed\, suggesting geological processes such as folding or faulting have influenced the LC along the  5-km length of the section.  Once the boundaries of the LC divisions are known\, geotechnical engineers have a greatly improved overall understanding of the ground conditions and how the ground will respond to engineering works such as tunnelling and deep excavations.  Broad engineering implications of the divisions are described and discussed\, citing case histories where possible. \nView This Talk In The Members’ Section.

SUMMARY:Percy Evans Lecture: Surfing the Waves of Time: Exploring Latin America's Passive Margins with an Innovative Sea Level Curve
DESCRIPTION:Dr. Douwe van der Meer\, CNOOC International\, Uxbridge \nAbstract: Recent exploration efforts in South American passive margin basins\, such as the Guyana-Suriname Basin\, have yielded significant success with over 10+ Bboe discovered\, primarily within the late Cretaceous play/mega-sequence. Most recently the Southern Atlantic margin\, spanning Brazil\, Uruguay\, and Argentina\, has also garnered industry attention\, particularly following discoveries at the conjugate margin of Namibia. \nIn an award-winning study by Van der Meer et al. (2022)\, plate tectonic eustasy estimates were updated using the 87Sr/86Sr record of seawater\, coupled with a novel glacio-eustasy estimates based on a recent Phanerozoic paleotemperature model (Scotese et al.\, 2021). This innovative Tectono-Glacio-Eustatic (TGE) curve for the entire Phanerozoic correlates well with mega-sequence stratigraphy in global passive margin basins. \nExamining key basins like Guyana\, the TGE curve aligns with the mega-sequences\, showcasing the influence of plate tectonic and glacio-eustatic drivers on the petroleum system. The petroleum system elements in deepwater\, correlate well with predictable patterns. \nSimilarly\, southern Atlantic basins also exhibit predictable elements of the drift play (post-Aptian)\, with the TGE curve serving as a tool for undrilled sections of the stratigraphy. This research underscores the interplay between plate tectonics\, glacio-eustasy\, and basin evolution\, offering valuable insights for future and ongoing exploration endeavours. \nBiography: Douwe van der Meer\, a tectonophysicist by background\, and seasoned explorationist by profession\, earned his M.Sc. at Utrecht University in 2002\, specializing in plate tectonic processes. Following a transformational sabbatical at the Norwegian Geological Survey in 2009\, he continued research on plate tectonics\, which led to a Ph.D. cum laude in 2017 and was recently honoured with the IAGR Best Paper award and medal. With over 20 years of experience at Shell\, Nexen\, and CNOOC\, Douwe has led various exploration New Ventures teams\, being based in the Netherlands\, UK\, and USA. A passionate Earth System enthusiast\, Douwe’s work and research encompasses all continents and eras from the Archean to Cenozoic. Currently serving as Sr. Manager New Ventures Latin America at CNOOC International\, Douwe continues to contribute his research expertise to the industry. His commitment to advancing understanding of Earth Systems\, coupled with significant applications to the oil and gas sector\, establishes him as subject matter expert in global exploration. \nView This Talk In The Members’ Section. \n

SUMMARY:The Thames in Hertfordshire and adjacent areas
DESCRIPTION:Talk by Professor David Bridgland\, University of Durham. \nHertfordshire would seem to be the only one of the Home Counties to have been abandoned by the Thames during the Quaternary.  It was squarely on the Thames course prior to southward diversion of the river ~450\,000 years ago\, the result of Britain’s most extensive glaciation.  The evidence for the erstwhile Hertfordshire Thames will be pieced together during the lecture\, with comparison made with neighbouring areas that have also furnished parts of the story and have supplied more recent refinements.   \nView This Talk In The Members’ Section.

SUMMARY:Outcrops & Subsurface examples of the EoCambrian petroleum system in Oman
DESCRIPTION:Talk by Professor Stuart Harker\, Retired. \nSouthern Oman has one of the oldest working petroleum systems in the world with source rocks\, reservoirs and productive traps in the Huqf Supergroup (520-600mya).  There are superb world class outcrops of these sediments exposed along the Indian Ocean coast and in the inland salt diapir province.  Reservoirs range in depositional environment from glacial clastics to peritidal stromatolitic carbonates.  Petroleum traps range from conventional tilted fault blocks and anticlines\, through salt induced anticlines to rafted carbonates and silicilyte.  In spite of over 70 years of exploration\, there remain many opportunities to discover additional reservoirs and traps. \nView This Talk In The Members’ Section.

SUMMARY:Dinosaurs: New Visions of a Lost World
DESCRIPTION:given by Prof. Mike Benton (Professor of Vertebrate Palaeontology\, University of Bristol) \n\n\n\nTwenty-five years ago\, the first feathered dinosaur was reported\, Sinosauropteryx. There has been a revolution in dinosaur palaeobiology since then\, driven by thousands of amazing specimens from China plus new analytical methods. \nIn 2010\, we were among the first to develop a new analytical method to identify the colour of feathers\, including the feathers of dinosaurs. Suddenly the ancient world came to life! \nSince then\, the methods have been criticised\, tested\, and applied to many exceptional fossils of dinosaurs and birds\, and the plumage colours and patterns reconstructed. These methods are scientific\, meaning they can be tested (and so far they have withstood critical testing)\, and they make definite predictions about the colours of dinosaurs and other extinct animals. \nOrder a copy here: https://bit.ly/DinosaursNewVisions \nMore information: \nhttps://thamesandhudson.com/dinosaurs-new-visions-of-a-lost-world-9780500052198 \nhttps://dinocolour.blogs.bristol.ac.uk/ \nView this talk in the Members’ Section.

SUMMARY:From shallow mine workings to deep basement rocks: A tour of UK low temperature geothermal resources
DESCRIPTION:given by Dr. Cat Hirst (Senior Engineering Geologist\, COWI\, Glasgow) \nFrom shallow mine workings to deep basement rocks: A tour of UK low temperature geothermal resources \nCatherine M. Hirst1\, Sally Jack1\,2 \n1COWI UK Ltd\, Fifth Floor\, 310 St Vincent Street\, Glasgow\, G2 5RG. \n2University of Strathclyde\, 16 Richmond St\, Glasgow\, G1 1XQ\, UK. \nThe UK has committed to be net zero by 2050 via the signing of the 2015 Paris Agreement and 2021 Glasgow Climate Pact. Space heating in the UK accounts for 42% of UK energy demand\, and natural gas is used to provide more than 90% of this heating and cooling demand. De-carbonising heat\, therefore\, has the potential to make a huge impact on the UK’s net zero aspirations. \nOver the past 25 years\, research into geothermal energy extraction from low enthalpy (temperature) resources within the UK has been increasing year-on-year. Whilst historically the UK has only ever had one working low temperature deep geothermal system (Southampton)\, there is scope for geothermal energy to make a significant contribution to the UK energy portfolio. More recently\, focus has fallen on the shallow (typically <500 m depth) geothermal systems associated with old\, abandoned mine workings. Our understanding of these systems is incomplete in the same way we have limited knowledge of the deep (>500 m depth) subsurface\, but what sets shallow resources apart from deeper resources is their accessibility. This talk aims to cover the background to geothermal heat generation\, the key differences between shallow and deep low temperature geothermal resources\, provide examples of deep low temperature resources in the UK and to showcase the work currently being completed by the University of Strathclyde and COWI to better characterise mine water geothermal resources. \nView this talk in the Members’ Section.

SUMMARY:A short history of buildings in six stones
DESCRIPTION:given by Dr. Tim Yates\, (Technical Director\, Building Research Establishment\, Garston.\n\nDoors open at 7:15pm\, tea & coffee available\, talk starts at 7:45pm.\n\nMany will be familiar with Neil MacGregor’s ‘A history of the world in 100 objects’ that retell humanity’s history through the objects we have made. This talk is on a much smaller scale with just six objects – all natural stones! But hopefully they will help us to see how our built heritage\, our built landscapes\, our towns\, cities and villages\, are shaped by the natural stones used in their construction.\nAlong the way we’ll look at the links to geography\, society\, technology\, and politics – and\, of course\, the geology of the rocks from which the stones were taken.\nWhy six stones? Well there’s no real reason but six felt about right in the time we have! And choice of the six – Caen Limestone\, Clunch\, Portland Limestone\, Welsh Slate\, York Sandstone\, and Aberdeen Granite – includes some of the most important building stones found in the UK but is also a personal choice that reflects my background and my work at Building Research Establishment for the last 37 years.

SUMMARY:Magmatic systems and the energy transition
DESCRIPTION:given by Prof. Jonathan Blundy (Royal Society Research Professor\, University of Oxford)  \nAbstract:\nThe transition to Net Zero will place unprecedented demand on natural resources requiring some new thinking about where to find them and how to extract them. In this talk I will explore the potential for magmatic systems\, such as those beneath volcanoes\, to provide accessible sources of both geothermal power and a diversity of metals including many that are essential for the energy transition. I will draw upon new research in volcanology\, igneous petrology\, economic geology and high-pressure and temperature experiments. \nView This Talk In The Members’ Section. \n

SUMMARY:The Moine Thrust Controversy
DESCRIPTION:given by Dr. Peter Gutteridge (Director\, Cambridge Carbonates) \nAbstract:\nThe NW Highlands of Scotland probably has the best scenery and geology in the world. You can find the oldest rocks in the British Isles\, the first evidence of life\, ancient landscapes carved out by preCambrian rivers and beautifully exposed Lower Palaeozoic clastic and carbonate sediments. These all form part of a major fold and thrust belt on which the metamorphosed Moine schists were emplaced. \nHowever\, geologist Roderick Impy Murchison saw this as a conformable succession. It is worth asking the question\, why did Victorian geologists so completely miss evidence that is so obvious to geologists today? The answers lie in the state of geological science at the time\, geopolitics and social climbing. Resolution of the Moine thrust controversy was a turning point in the history of geology gave us the foundations of the science of geology as we now know it. \nView this talk in the Members’ Section.

SUMMARY:Visions of Nature.  Art\, science and natural history museums
DESCRIPTION:given by Prof. Paul Smith (Director University of Oxford\, Natural History Museum). \nAbstract \n\n\n\nIn an era of polarised opinion and a difficulty in determining the veracity of information\, science museums play an important role as ‘honest brokers’ in both enabling and encouraging public debate around science. Surveys on both side of the Atlantic have demonstrated that museums are amongst the most trusted providers of information\, but first they need audiences to discuss and debate with. \nFor the last few years\, Oxford University Museum of Natural History has been operating an innovative series of exhibitions entitled Contemporary Science & Society. Each exhibition is an interdisciplinary investigation of an aspect of current science research and interweaves the scientific storytelling with related contemporary art that enhances the audience appeal. The exhibition is\, however\, only a starting point for a broader programme of events that range from lectures and debates to more informal science fairs\, art interventions and comedy nights. Audiences for each exhibition range up to 245\,000 and both qualitative and quantitative evaluation show that the content has had the ability to change people’s decision-making and behaviours. \nThe lecture will examine a variety of recent exhibitions\, the range of issues that the exhibition series is seeking to address\, and the role of a natural history museum in modern society. \n\nView this talk in the Members’ Section.

SUMMARY:Percy Evans Lecture: The Norber Erratics
DESCRIPTION:given by Clive Maton (Honorary President\, HGS) \nAbstract\nThe Norber Erratics are well known and are featured in geological text books and numerous local guides to the Yorkshire Dales. This is partially due to their large size\, the very large numbers\, and all being located in a relatively small area; but they are best known for their emplacement on Carboniferous Limestone pedestals.They have been the subject of much study. The first scientific papers were published in the late 19th Century  and many more have described and discussed them in the last 150 years. My study of them started as they were included in the area of my Map & Thesis\, which formed part of my Geology degree\, and I have continued to visit the area for post graduate field work. This\, together with my recent research on the source and flow of the erratics\, form the basis of the lecture.  \nView this talk in the Members’ Section.
