February 5th: seminar on climate correlation and modelling magmatic processes
On February 5th at 15, in B7 room (Department of Earth and Environmental Sciences, via Ferrata Pavia), Nick Pearce (Aberystwyth University) will give the presentation Tephra glass shard geochemistry: applications from climate correlation to modelling magmatic processes.
Tephra studies as a tool for stratigraphic correlation started in Iceland the 1940s, and after 75 years, have become a key component of the Quaternary stratigraphers’ tool-kit, and the number of studies involving tephra analysis roughly doubles every decade. In this presentation, the development of LA-ICP-MS methods for the analysis of tephras will be described, and a series of applications will be discussed where trace element data has been important.
