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 on modern oceanic lithosphere and ophiolites have revealed high degrees of
chemical and isotopic heterogeneity in the mantle, as well as isotopic contrasts between …

Two distinct igneous differentiation trends–the tholeiitic and calc-alkaline–give rise to Earth's
oceanic and continental crust, respectively. Mantle melting at mid-ocean ridges produces …

Kane Megamullion, an oceanic core complex near the Mid-Atlantic Ridge (MAR) abutting
the Kane Transform, exposes nearly the full plutonic foundation of the MARK paleo-ridge …

Abyssal peridotites, the depleted solid residues of ocean ridge melting, are the most direct
samples available to assess upper oceanic mantle composition. We present detailed …

Basal peridotites above the metamorphic sole outcropped around Wadi Sarami in the
central Oman ophiolite give us an excellent opportunity to understand the spatial extent of …

With the aim of constraining the influence of the surrounding plates on the Late Paleozoic–
Mesozoic paleogeographic and tectonic evolution of the southern North China Craton …

Mapping the compositional variability of the Earth's mantle is fundamental for understanding
mantle dynamics, crustal recycling and melt generation. The geochemistry of intraplate …

Adakites are unusual felsic igneous rocks commonly associated with asthenospheric slab
window opening or fast subduction of a young (< 25 Ma) oceanic plate that may allow slab …

Ranges in clinopyroxene trace element contents of 2–3 orders of magnitude occur over< 2
cm distance in peridotite samples from the Atlantis II Fracture Zone on the Southwest Indian …
