Generation of sodium-rich magmas from newly underplated basaltic crust.
He also suggested that the more acidic varieties were derived from this basaltic melt via fractional crystallization.
In particular, is the source of within-plate basaltic magmas in an extensional setting the lithosphere, convecting asthenosphere or both?
The aim is to place constraints on the geochemical evolution of these basaltic magmas.
The majority of these are rhyolitic/dacitic/trondhjemitic and basaltic, commonly hosting massive sulphide deposits of economic importance.
Intra-oceanic arcs are volumetrically dominated by basaltic volcanic products.
The latter consist mainly of basaltic pillowed and massif lava flows.
These characteristics suggest that the initiation of sinistral strike-slip movement behind the trench caused the basaltic volcanism subsequent to rifting.
