A history of the plate tectonics of Britain (Part 4): A quiet crust with a long memory – tectonic inheritance in the modern British landscape

Modern Britain lies far from active plate boundaries. It has no active volcanoes and experiences only minor earthquakes, and is often described as tectonically quiet. Yet its landscape is anything but passive. Hills and lowlands, coastlines and drainage patterns all reflect a deep structural inheritance established during earlier phases of continental collision, collapse and rifting.

A history of the plate tectonics of Britain (Part 3): Britain breaks apart – rifting, volcanoes and the birth of the Atlantic

By the end of the Carboniferous, Britain had already passed through more than one major phase of mountain building, each followed by long periods of erosion and structural collapse. The Caledonian mountains were long eroded, and the Variscan belt of southern Britain was entering its final stages of decay. Yet tectonic influence did not fade away. Instead, the dominant regime changed. Britain was no longer being compressed – it was being stretched.

A history of the plate tectonics in Britain (Part 2): When mountains fall – collapse, basins and the foundations of Britain’s lowlands

The collision that assembled Britain at the end of the Silurian (see A history of the plate tectonics of Britain (part 1): Britain assembled – oceans, collisions and the making of a geological patchwork) did not mark the end of tectonic influence on the landscape. Instead, it marked the beginning of a new phase – one that is often less intuitively grasped, but just as important. Mountain belts are temporary features. Once continental collision ceases, thickened crust becomes gravitationally unstable. Erosion strips material from the surface, while extension and faulting affect the deep roots of the orogen. The geological record that follows is not one of rising peaks, but of collapse, subsidence and redistribution.

A history of the plate tectonics of Britain (Part 1): Britain assembled – oceans, collisions and the making of a geological patchwork

Britain is often described as geologically quiet. There are no active volcanoes, no subduction zones, and only modest earthquakes. Yet, for its size, few countries display such a concentration of geological variety. Mountain uplands, volcanic terrains, deeply folded rocks, and ancient metamorphic cores all occur within a relatively small area. The explanation for this diversity lies not in Britain’s present tectonic setting, but in a long and complex tectonic history that assembled the country piece by piece from fragments that originated far apart.

Book review: GeoHibernica: The Irish Landscapes, Peoples and Cultures, by Paul Lyle

Paul Lyle begins GeoHibernica with a slightly mischievous acknowledgement: the book exists only because the author of GeoBritannica was unable to take on its Irish counterpart himself. It is a revealing admission, and one that immediately invites comparison between the two works. That comparison is instructive, although not always in the ways one might expect.

Book review: Trilobites, Dinosaurs and Mammoths: An introduction to the prehistory of the British Isles, by James McKay (for the Palaeontological Association)

This is an interesting little booklet and very much a new departure for the Palaeontological Association. You will be aware that I have reviewed several of its many excellent fossil guides in this magazine. However, this recently published tome is somewhat different.

Book review: Measures for Measure: Geology and the Industrial Revolution, by Mike Leeder

I sat down to read this over Christmas and what a good read it turned out to be. The appropriate word is ‘eclectic’ – because Measures for Measure is written for all us with an interest in the industrial history of Great Britain, and its impact on the landscape, economy, social history and culture. It’s a great read as it dots about linking places and ideas together, with the link always being the geology.

Rummages through the core collection of British cephalopods (Part 1): Introduction

Neale Monks (UK) Alongside trilobites, ammonites are by far the most popular invertebrate fossils. Whether you’re an enthusiastic fieldworker or more of an armchair geologist, chances are that your collection includes a fair number of ammonites of one sort or another. These may well have names and localities, but details … Read More

Book review: Trilobites of the British Isles, by Dr Robert Kennedy and Sinclair Stammers

I’ve been waiting for a book like this for a very long time and am delighted that a publication of this quality has now arrived. New books covering British palaeontology are always welcomed by this magazine and we published an article a while ago by the founder of the publisher of this book – David Penney – explaining the need for such guides.

Dean R Lomax (UK) Palaeontology and Britain In its simplest form, palaeontology is the study of prehistoric life, through examination of fossils. Palaeontology is, however, not just dinosaurs. Dinosaurs constitute a miniscule portion of what palaeontology is. After all, a myriad of different, and often down-right bizarre, organisms lived long … Read More
