Magmas in Scotland

Synopsis

Begins by establishing that igneous rocks exist in Skye/BTVP, e.g. lava flow features. Paleo-magnetism reveals that magmatism was related to the opening of the Atlantic. What kind of magmas are involved, and why? Scenic and map-based overview of plateau basalts, gabbro (Cuillin) granits (Red Hills) anbd ignimbrites. Looks at a geochemical approach to constrain origins and relationships between these magmas. Compares Skye magmas with MORB of the Atlantic to conclude that contrasting lithospheric structure and processes influence magma compositions.

Notes

NB. As of May 2016 Open University Worldwide are no longer distributing DVDs. They have posted this message on their website: ‘Unfortunately Open University Worldwide Limited has decided that product sales are no longer viable given the reduced funding to Higher Education institutions and diminishing demand for the products we have traditionally stocked. At present the Open University Students Association (OUSA) will continue to sell the "Good Study Guide", and we are in discussion with other possible distributors to continue to make The Open University’s products available for purchase. As soon as we have any information on other channels of distribution we will update this notice’. Some products are still available via second hand dealers on Amazon.co.uk
