Kimberlites and their precious diamondiferous cargo

This event has ended.

In this talk, Maier will take the audience on a journey exploring the discovery of kimberlites and their diamond deposits. The focus will be on the tumultuous decades from 1864 when diamonds were discovered along the Orange River in South Africa, triggering the world’s largest diamond rush and heralding the end of the Griqua and Boer Republics and the rise of the southern African British Empire.

Portraits of Cecil Rhodes and Barney Barnato will be complemented by lots of images of famous diamonds (some of them on Royals). In addition, an overview of the formation of diamonds and exploration techniques for their discovery will be provided.

Volcanoes - all you need to know series

This lecture series will encompass the diversity of volcanoes, their functioning and products, together with the nature of eruptions and their attendant problems of predictions plus their ensuing past and present environmental and biological impacts.

Did you know that the majority of volcanic eruptions – maybe even 90% – occur under water and of which we are largely unaware? There remains a very great deal we don't know about volcanoes, but many exciting new insights are emerging from ongoing research.

Should you require the question and answer sessions to be in Welsh, please email edwardsd2@cardiff.ac.uk at least two weeks before the event.
