Mar  202228Prof. Derek Siveter, University Museum of Natural History, Oxford. “The Herefordshire Lagerstätte: a remarkable window into Silurian marine life” The Herefordshire Lagerstätte is an exceptional, globally important fossil deposit of mid-Silurian age (about 430 Ma), occurring in the Anglo-Welsh Basin. The fossils are hosted in nodules in a volcaniclastic layer and are represented by a rich soft-bodied invertebrate fauna. These are exquisitely preserved in the round and are studied mostly through use of physical-optical tomography. Digital images are combined by computer to reconstruct the animal as a three-dimensional virtual model that can be examined interactively on screen. The digital data can also be used to generate a physical model of the fossil through rapid prototyping technologies. Soft-bodied fossils belonging to the Cambrian Period have been fundamental for our understanding of the early evolution of animal life during the ‘Cambrian Explosion’ event. However, soft-bodied faunas from the Silurian are extremely rare, and the Herefordshire fossils are contributing much to our understanding of the palaeobiology of the wide variety of major invertebrate groups represented, and thus to the early Phanerozoic history of life on Earth.td>MMH+ZOOM Vol
Feb 202228Dr Carl Stevenson, Birmingham University, “Tectonics and magmatic structures in the West Midlands
The kinematics and history of major tectonic structures in the West Midlands and surrounding areas is linked with the ascent and emplacement of magma. Results from a series of student projects examining features including the Wren’s Nest, Lickey Hills, Malvern Lineament and the Rowley Regis Dolerite, Clee Hill Sill and other smaller intrusions are discussed and an emerging model presented for criticism. Can we link the kinematics of major tectonic structures to these intrusions? Does their timing/age of emplacement fit the tectonic history?

Jan 202224Prof Ian Fairchild, Birmingham University, “Stromatolites: Making Mountains out of Microbes
For most of Earth history the only macroscopic evidence of life comes from the intricately layered rocks called stromatolites. Like trace fossils they record an interaction between organisms and sedimentary processes. The key players are the cyanobacteria, formerly known as blue-green algae, which played a vital role in oxygenating the Earth through their photosynthesis. Build-up of sediments and precipitates over time under the sticky surface mats created by communities of such organisms can make limestone and dolomite masses up to hundreds of metres thick. Stromatolites reveal many fascinating stories of past environments and examples from several continents will be discussed.

Nov 202129Dr Seb Watt, Birmingham University, “Volcanic Tsunamis: Krakatau, 1883 and 2018
Although most tsunamis are generated by earthquakes, those generated by volcanic processes can cause devastating impacts. Volcanic-tsunami generation remains a poorly understood process but the hazard is significant, as demonstrated by the catastrophic eruption of Krakatau in 1883, where most of the 36,000 deaths were caused by the associated tsunami. A variety of volcanic processes can generate tsunamis, with unpredictable timing and the potential for locally extreme wave heights. Here, I will summarise results from ongoing research at Krakatau and other volcanic islands, drawing on insights from the 1883 eruption as well as the volcanic-landslide generated tsunami at Anak Krakatau in December 2018.

Oct 202125Prof. Rob Strachan, Portsmouth University, “A geotraverse across Shetland: new insights into the Scottish Caledonides“.
Shetland is a microcosm of the Scottish Caledonides, containing potential correlatives of the Moine Thrust Zone, the Moine and Dalradian supergroups, and an overlying ophiolite derived from the Iapetus Ocean. New geochronology results shed exciting new insights into the geological evolution of this hitherto relatively poorly known part of Scotland.

2018 Mon 19th Mike Brooks Travel back to Martley’s deep time past – reconstructions of how the area may have appeared at various times in the geological past. A presentation of the Voyages in Deep Time project and one of its outcomes the Voyager app, which includes a deep time Voyage of the Martley area. Another aspect of the project that will be shown, is the use of drones in the Black Mountains and Wye valley, to help interpret the geology and geomorphology.
