The formation of amphibole cumulates beneath arc volcanoes is a key control on magma geochemistry, and generates a hydrous lower crust. Despite being widely inferred from trace element geochemistry as ...
This is a preview. Log in through your library . Abstract Boisa Island is the tip of a Quaternary island-arc volcano. It consists of an older cone made up of porphyritic, amphibole-free, mafic rocks, ...
Discriminant function analysis (DFA) of Ca-rich clinopyroxene and amphibole from modern arc volcanics allows identification of the parent magma type (basalt, andesite, or dacite + rhyolite). With a ...
