Geochemistry of basalts: Deep Sea Drilling Project Sites 482, 483, and 485 near the Tamayo Fracture Zone, Gulf of California.

Abstract

Major and trace element chemistry of the basalts from these sites reveals complex variation patterns which clearly indicate the influence of several types and hierarchies of petrogenetic province. In general, the geometric and temporal character of magmatic accretion processes in the Gulf of California appears to be intermediate between the processes observed along superfast sections of the East Pacific Rise, and those along the slow spreading Mid Atlantic Ridge. -after Authors chemistry basalts petrogenetic province magmatic accretion processes Gulf of California East Pacific Rise Mid Atlantic Ridge DSDP Leg 65 Sites 482 483 485
