"The Elgin Reptiles: a window on the origin of modern faunas" Dr Davide Foffa
For more than 100 years, scientists have puzzled over the Elgin Reptiles - unusual fossils that exist as cavities hidden within rocks over 230 million years ago in what is now Scotland. Now, thanks to modern technology that is advancing the field of palaeontology, we can extract previously unavailable detail, uncovering the secrets of these ancient animals, the ecosystems in which they lived, and the origin of charismatic extinct groups. The Triassic Elgin fauna include some of the oldest ancestors and cousins of crocodiles, lizards, dinosaurs (and therefore birds) and pterosaurs.

Presidents Lecture February 2022 - Is all lava actually ash?
มุมมอง 2062 ปีที่แล้ว
Dr Hugh Tuffen presents recent evidence, from textures and models, that silicic lavas are in fact welded ash deposits and explore whether the same could also be true for some basaltic lavas. For more detail here is a link to a recent paper: www.science.org/doi/10.1126/sciadv.aba7940
UV-B radiation was the Devonian-Carboniferous boundary terrestrial extinction kill mechanism
มุมมอง 2012 ปีที่แล้ว
Some 359 million years ago there was a terrestrial mass extinction at the boundary between the Devonian and Carboniferous Periods. Major extinctions include all the armoured fish and important groups of land plants. In East Greenland there are a number of localities where we can find the terrestrial extinction layer. These were in the arid centre of the Old Red Sandstone Continent some 1000 km ...
Southern Spain Geodynamics and comparable areas of the western Mediterranean
มุมมอง 4093 ปีที่แล้ว
Southern Spain, southern Italy and the Aegean region are places familiar to many through holiday visits but few realise how dynamic these places are at the present day and in the not so distant geological past (Miocene through Recent). Southern Spain (Andalucia) consists of uplifted mountain chains (sierras) where metamorphic rocks are exposed, separated by intramontane sedimentary basins. Thes...

มุมมอง 1013 ปีที่แล้ว
With increasing energy costs and the need to decarbonise our economies geothermal energy can play an important part in heating buildings. Net-zero carbon emission targets require significant progress to be made in the decarbonisation of heat. Utilisation of the warm water in flooded, abandoned coal mines beneath many of the UK’s towns and cities could offer a substantial opportunity for decarbo...
The geology of carbon capture and storage: why we need it, what it is and what is holding it up
มุมมอง 1.9K3 ปีที่แล้ว
Professor Richard Worden Department of Earth, Oceans and Ecological Science, University of Liverpool Carbon capture and storage (CCS) is a strategy designed to cut emission of the greenhouse gas carbon dioxide. Carbon (dioxide) emissions result from practically all human activity from farming, cement, steel and other metal manufacture, as well as electricity, heat and power generation by burnin...
It's all relative: the up, downs, tilting and rebounds of ancient sea level. Prof. Pete Burgess
มุมมอง 1303 ปีที่แล้ว
What is sea-level? Why does global sea level change? How do we determine ancient sea-level? Global sea-level through geological time. Tilted continents, isostasy and relative sea-level change.
Looking into Icelandic volcanoes. Dr Hugh Tuffen
มุมมอง 5263 ปีที่แล้ว
In this lecture we visit Iceland in the North Atlantic Igneous Province on the mid Atlantic Ridge where new crust is being created. Learn about basaltic and rhyolitic magma, how magma chambers fill and store magma. See dykes propagate laterally, sometimes travelling 50km through the crust. Watch a geothermal exploration well tap into a live magma in the search for supercritical heated steam and...
Glaciation of the North Sea Basin, Prof Mads Huuse
มุมมอง 6213 ปีที่แล้ว
Since the end of the Eocene, Earth’s climate has largely been in an ice house state with glaciation on the poles and varying intensity of glaciation at lower latitudes, as far south as the Isles of Scilly during the late Pleistocene. The study of glacial deposits in NW Europe is centuries old and Darwin famously recognised erratics and landforms as caused by extensive glaciations. Despite inten...
Deep geological disposal of radioactive waste: The role of geoscience.
มุมมอง 2754 ปีที่แล้ว
Britain has been accumulating radioactive waste for more than 70 years. Radioactive Waste Management (RWM) is engaged in delivering one of the largest environmental projects ever undertaken in Britain: a deep geological disposal facility (GDF) in which higher activity radioactive waste from England and Wales will be disposed of permanently. This presentation has two main aims: to give a flavour...
Humans have re-configured nature: A geological perspective on the future of planet Earth
มุมมอง 3734 ปีที่แล้ว
Patterns of human consumption have profoundly changed life on Earth and have left a distinctive geological signal in the fossil record of our crops and domesticated animals, and in the many species we have translocated around the world. Will our geological legacy be rock strata filled with plastics followed by evidence of a mass extinction of life, or will that record show evidence of our inter...
I wish Id seen this live. I have many questions. Really interesting talk. Thank you.
Cap rock across the closure need to be map and the sealing capacity with respect to CO2 need to be evaluated to prevent leakage
Katla, will be a VeI 6 eruption in spring 2023
Professor Worden, on halite precipitation: If you were doing high-level screening of aquifers/depleted O&G fields is there a rule of thumb go/no-go salinity percentage? I understand the geochemistry and injected fluid interactions are complicated so it's not necessarily that simple, or is it? Fantastic presentation.
The more we know about volcanoes, the more we realize how much there is still to discover. Soon, volcanology models might out-complex meteorology. So much progress in just a few decades.
good
I seem to remember that a similar process happened in the lead up to the 2018 eruption in Hawaii
I wonder if there is a link between rhyolite detection issues, and eruptions like the Pinatubo taking everyone by surprise.
Yea that was a big surprise, a phreatic eruption/ explosion out of nowhere that managed to reach 40,000ft!!!! Water is the single biggest determining factor in every single huge eruption. Yellowstone has an endless supply of water available and will be the cause for its next major eruption, probably a VeI 5 eruption
Thank you , I'm an OUGS member who flew over the Holuhraun eruption with Extreme Iceland . Also went down Thrinukagigar .
A great first Zoom lecture for Westmorland Geological Society.
