RU Padova

The 200 km long Foum Zguid dyk, CAMP,e in Morocco

Research unit of Padova

Aims

The UniPD RU aims at studying the basaltic and gabbroic rocks from Mesozoic LIPs. Some LIPs (e.g. CAMP) were previously sampled, intrusive rocks from Skaergaard will be provided through collaboration (C. Tegner, Aarhus University), while those from the Wrangellia and Paranà need to be sampled. The goals of these studies are two-fold:

1) refine age relationships between LIP magmatism and major biotic turn-over events. This is in particular important for Wrangellia, which appears to be correlated to a significant biological turn-over event during the Carnian and whose age is very poorly constrained (Green et al., 2010 and reference therein).

2) define the plumbing system of LIPs, that will be achieved through the study of i) the deformation mechanism of layered intrusions through SEM-EBSD analysis on oriented samples from the Skaergaard intrusion, ii) the P-T-fO2 conditions of the crystal cargo from LIP basalts and iii) the pristine volatile element contents through SIMS and micro-Raman analysis of S and C in phenocrysts and MI. Isotopic analysis of these volatile elements will also be used to constrain their mantle or crustal origins.
