Plate Tectonics Subgroup




The Plate Tectonics Subgroup (PTSG) meets during the Autumn, Winter and Spring on the first Thursday in each month at Malvern Cube from 14:00 to 16:00 hrs.


The original aim of the group, formed 4 years ago, was to obtain a better understanding of the relatively new science of Plate Tectonics, which is only about 50 years old, and now underpins modern structural geology. New ideas and discoveries are still being made and we attempt to keep up with the science and associated areas like volcanism, earthquakes, orogeny’s and deeper processes within the Earth’s mantle and core.


More recently we have been reviewing the main Group’s major field trips both in the UK and abroad from a Plate Tectonic perspective. So far in 2017 we have reviewed the trip to Bude in 2016 and plan to do the same for the trip to Tenby at our October 2017 meeting.


Also in 2017 we have looked at images from space missions like Cassini for evidence of Plate Tectonic processes occurring on other planets, including the moons of Saturn.


At our December 2017 meeting we plan to explore all the techniques available for dating rocks and minerals over geological time. These techniques have become very sophisticated and accurate and have led to radical changes in theories of how the Earth formed and come to be like it is through Plate Tectonics.


New members are always welcome and each meeting more or less stands on its own. However we do have a good deal of material which new members can access to catch up on what we have done in the past.
