Major and trace element abundances of igneous rocks from DSDP Site 37-334

Listed in PANGAEA and DataCite — shown once because both records carry DOI 10.1594/pangaea.695954

REE abundances in gabbros and peridotites from Site 334 of DSDP Leg 37 show that these rocks are cumulates produced by fractional crystallization of a primitive oceanic tholeiite magma.

Description

They may be part of a layered oceanic complex. The REE distributions in the residual liquids left after such a fractionation are similar to those of incompatible element-depleted oceanic tholeiites.

The REE data indicate that the basalts which overlie the gabbro-peridotite complex, are not genetically related to plutonic rocks.
