Mantle-derived magmas are traditionally assumed to originate by melting of an upper mantle
consisting of uniform spinel-or garnet peridotite dominated by olivine. However, extensive …

Sediment contribution to the mantle is the key step for the generation of orogenic
magmatism to produce its isotopic and geochemical inventory. Even though they are …

We present a comprehensive petrographic, mineralogical and geochemical study of calc-
alkaline lamprophyres (CAL) from the Archean Yilgarn Craton, Western Australia. Previous …

Melt‐peridotite interaction is the key process causing lithological and mineralogical
modification in the lithospheric mantle beneath the North China Craton (NCC). However, the …

High-MgO lamproite and lamproite-like (ie lamprophyric) ultrapotassic rocks are recurrent in
the Mediterranean and surrounding regions. They are associated in space and time with …

Magma mixing is a widespread magmagenic process. However, its significance in the
formation of ultrapotassic magmas has been largely overlooked so far as they are commonly …

Fast elemental map** using laser ablation-inductively coupled plasma-time of flight-mass
spectrometry (LA-ICP-TOF-MS) was applied to a set of chondritic meteorite samples, more …

Sedimentary carbon may be transferred from subducting slabs to the overlying mantle
wedge as a component of sediment-derived melts and contribute to carbon output in …

In this study, we investigate phlogopite-rich pyroxenite from a major terrain boundary, ie, the
interface of Nallamalai Fold Belt and Nellore schist belt, in southern India. Petrographic …

Widely distributed Oligocene− Miocene ultrapotassic volcanic rocks in the Lhasa terrane of
southern Tibet have been associated with the melting of the lithospheric mantle, plateau …
