Chondrite normalized rare earth element (REE) patterns of zircons generally have enriched
Ce values relative to La and Pr, and depleted Eu values relative to Sm and Gd. High Ce …

Quartz and rutile were synthesized from silica-saturated aqueous fluids between 5 and 20

Abundant carbon was identified on Mercury by MESSENGER, which is interpreted as the
remnant of a primordial graphite flotation crust, suggesting that the magma ocean and core …

The solidus and near-solidus melting behavior of a primitive undepleted peridotite

Experimental diffusion couples were used to study chemical diffusion between molten
rhyolite and basalt with special emphasis on the associated fractionation of calcium and …

The study of siderophile element isotope compositions in planetary mantles offers a new
methodology to constrain the temperatures of core formation, provided there is an …

This study presents new phase equilibrium data on primitive mantle peridotite (0.33 wt% Na
