On February 3rd, at 12:00, in the “Aula Riunioni” of the Institute of Geosciences and Georisources (Area della Ricerca di Pisa), Professor Nicholas Pearce will give a seminar entitled: “Tephra glass shard geochemistry: applications from climate correlation to modelling magmatic processes".
A brief description of the event is listed below:
The study of tephra layers (volcaniclastic material deposited in distal settings) is a well-established and widely accepted stratigraphic tool to date and correlate quaternary successions. Improvements in the mass spectrometry coupled will laser ablation technology significantly amplified the potential applications of this methods, enabling detailed fingerprinting and characterization of the volcanic layers.
With his seminar, Prof. Pearce will provide interesting insights into this improved methodology, illustrating his studies concerning the Youngest Toba Tuff, a tephra related to the famous Toba Eruption (75 Ka), one of the main volcanic events in the Quaternary, from Northern Sumatra (Indonesia).
