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 …

Abstract The Eastern Australian Volcanic Province (EAVP) is a∼ 3800 km discontinuous
belt of Cenozoic mafic intraplate volcanoes along the eastern seaboard of Australia. EAVP …

Siliceous slab-derived partial melts infiltrate the sub-arc mantle and cause rock-melt
reactions, which govern the formation of diverse primary arc magmas and lithological …

Magmatic processing in the lower crust of thick-crusted (> 40 km) arcs generates garnet-rich
clinopyroxenite residues (arclogites) that are denser than the underlying mantle and …

The geodynamic evolution of the proto-northern Indian continental margin during
Paleoproterozoic is widely debated. The proposed models include (i) a mantle plume …

Arc magma generation and evolution are affected by transcrustal processes, such as
assimilation and fractional crystallisation, and source processes like slab influx into the …

Pyroxenite-peridotite sequences from the External Liguride (EL) Jurassic ophiolites
(Northern Apennines, Italy) consist of portions of fertile MORB mantle that were modified by …

The new mckelveyite group mineral alicewilsonite-(YCe), ideally Na 2 Sr 2 YCe (CO 3) 6⋅
3H 2 O, was found at Mont Saint-Hilaire, Quebec, Canada, and subsequently at the Saint …

The role of carbon-rich or carbonatitic melts as an important metasomatizing agent in the
Earth's mantle is supported by direct and indirect evidence of their involvement, ranging from …

How eclogite/pyroxenite‐derived melts evolve through the refractory lithosphere above a
plume remains poorly understood. Here we conducted layered experiments of reaction …
