TL;DR: In this paper, a comprehensive analysis of the basement terranes in the EB, a late Neoarchean (~ 2.5-2.6 ǫ) intra-oceanic arc system with relict MORB-like basaltic rocks bordering the northwestern margin of the continental nucleus is presented.

Chemical and isotopic systematics of oceanic basalt : implications for mantle composition and processes
TL;DR: In this article, trace-element data for mid-ocean ridge basalts and ocean island basalts are used to formulate chemical systematics for oceanic basalts, interpreted in terms of partial-melting conditions, variations in residual mineralogy, involvement of subducted sediment, recycling of oceanic lithosphere and processes within the low velocity zone.

Geochemistry of eocene calc-alkaline volcanic rocks from the Kastamonu area, Northern Turkey
TL;DR: In this paper, the Pontic eocene volcanic rocks cropping out in the Kastamonu area, Pontic chain of Northern Turkey were analyzed and the SiO2% versus K2O% relationship showed that the analyzed samples belong to two major groups: the basaltic andesitic and the andesite ones.
