Scotland rocks!

A group of geoscientists may be one step closer to knowing where Scotland originally came from after a conference at the University of St Andrews this weekend.

The two-day event, taking place on 16 and 17 February, has attracted around 40 participants from the UK and Ireland, Scandinavia and North America.

To be held in the School of Geography and Geosciences, the event will be convened by Ian Alsop, Grahame Oliver and Tony Prave of the Geoscience Research Group. It follows recent funding awarded to the group from the Carnegie Trust to study the nature and origin of rocks on either side of the Great Glen Fault.

The conference reflects a resurgence and growing interest in the origins of the Scottish Highlands which form a critical link between the geology of Scandinavia and North America. It is hoped that discussions at the conference will help unravel some of these complicated rocks in the Scottish Highlands and that a few more pieces of this ancient geological jigsaw puzzle will fall in to place.

Dr Alsop said, “Many of the presentations to be given concern the isotopic dating of the timing and age of geological events which have affected Scotland. The Scottish rocks represent vast periods of time from the Lewisian rocks of the Outer Hebrides (which are the very oldest rocks in the British Isles at 2,700 million years old) to the Caledonian mountain chain which stretches from Scandinavia, through Scotland to North America at 400 million years old. To put this enormous amount of time in to perspective, we can divide geological history up into a simple 24 hour clock, the Lewisian rocks formed at 9.55, the Caledonian Mountains at 21.55 and humans arrived at one minute before midnight! The ancient rocks of the Scottish Landscape have a huge earth history locked up within them.”
