Abyssal peridotites are ultramafic rocks collected from mid-ocean ridges that are the
residues of adiabatic decompression melting. Their compositions provide information on the …

Studies of mantle xenoliths have confirmed that Archean subcontinental lithospheric mantle
(SCLM) is highly depleted in basaltic components (such as Al, Ca and Na) due to high …

We derive an estimate for the chemical composition of the depleted MORB mantle (DMM),
the source reservoir to mid-ocean ridge basalts (MORBs), which represents at least 30% the …

We present new analytical data of major and trace elements for the geological MPI‐DING
glasses KL2‐G, ML3B‐G, StHs6/80‐G, GOR128‐G, GOR132‐G, BM90/21‐G, T1‐G, and …

Abstract The Early Permian magmatism in Tarim, NW China comprises diamondiferous
kimberlites, lamprophyres, flood basalts, Fe–Ti oxide ore-bearing layered mafic–ultramafic …

Rocks in the Earth's uppermost sub-oceanic mantle, known as abyssal peridotites, have lost
variable but generally large amounts of basaltic melt, which subsequently forms the oceanic …

Cenozoic, post-collisional, potassic and ultrapotassic igneous rocks in the North Qiangtang,
Songpan–Ganzi and North Kunlun terranes of the northern Tibetan Plateau are distributed …

The Earth's mantle beneath ocean ridges is widely thought to be depleted by previous melt
extraction, but well homogenized by convective stirring. This inference of homogeneity has …

A detailed petrological and geochemical study of low-temperature peridotite xenoliths from
Kimberley and northern Lesotho is presented to constrain the processes that led to the …

An extensive dataset of ocean island basalt (OIB) compositions highlight that their titanium
(Ti) contents are generally too high to be derived from melting of a peridotitic mantle. Even …
