Ophiolites, which represent segments of oceanic lithosphere obducted onto the continental
crust, provide an important window into processes such as continental rifting, mantle …

Diamond crystallization ages are essential information for science and industry, leading to
an understanding of how, why, and where diamonds form in Earth and how best to find …

Cratonic lithospheric mantle is composed of predominantly refractory materials that formed
at higher mantle potential temperatures (TP) than recorded in non-cratonic peridotites. It also …

The compositional variability of the lithospheric mantle at extensional settings is largely
caused by the reactive percolation of uprising melts in the thermal boundary layer and in …

The concentrations of highly siderophile elements (HSE: Re, Os, Ir, Ru, Pt, Rh, Pd, Au) and
187Os/188Os isotope compositions have been determined for 67 subsamples of six lunar …

Tectonically emplaced mantle rocks, such as ophiolites, abyssal peridotites, and orogenic
peridotite massifs, provide a principle constraint on the composition of and processes in the …

The nature (ie, sub-oceanic, sub-arc or sub-continental) of ophiolitic mantle peridotites from
the eastern Neo-Tethyan domain in southern Tibet has been hotly debated. This uncertainty …

BACKGROUND Through the 1980s, much of the information obtained regarding mantle
composition and its inherent heterogeneity was derived through indirect evidence, ie, the …

Highly depleted harzburgites and dunites were recovered from ODP Hole 1274A, near the
intersection between the Mid-Atlantic Ocean Ridge and the 15° 20′ N Fracture Zone. In …

Mantle xenoliths from the Kerguelen Archipelago record a complex multistage history
involving a high degree (15 to 25%) partial melting that created a harzburgitic mantle …
