Geochemical fingerprinting of oceanic basalts with applications to ophiolite classification and the search for Archean oceanic crust
JA Pearce - Lithos, 2008 - Elsevier
Two geochemical proxies are particularly important for the identification and classification of
oceanic basalts: the Th–Nb proxy for crustal input and hence for demonstrating an oceanic …

High Sr/Y and La/Yb ratios: the meaning of the “adakitic signature”
JF Moyen - Lithos, 2009 - Elsevier
The name of “adakite” is used to describe a far too large group of rocks, whose sole common
feature is high Sr/Y and La/Yb ratios. However, such a signature can be achieved via …

When did plate tectonics begin? Evidence from the geologic record
Modern-style plate tectonics can be tracked into the geologic past with petrotectonic
assemblages and other plate-tectonic indicators. These indicators suggest that modern plate …
