Extremely voluminous magmatic systems known as large igneous provinces (LIPs)
punctuate Earth's history, and the gases they release plausibly link large-scale geodynamic …

Tracking the final fate of subducting carbon is crucial to understanding global carbon cycles
and climate changes in the history of the Earth. Available geochemical tracers such as …

Carbonate, the major carbon reservoir on Earth's surface, can enter into the mantle by
subduction. However, evidence for recycled surficial carbonates in the deep mantle is still …

Phanerozoic orogenic gold mineralization at craton margins is related to the metasomatism
of the lithospheric mantle by crustal material. Slab subduction transfers Au from the crust to …

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

In order to better constrain the Mg isotopic composition of the mantle, we have analysed
twenty-eight samples of both oceanic and continental peridotite using a high-precision …

Mantle plumes originate at depths near the core− mantle boundary (~ 2,800 km). As such,
they provide invaluable information about the composition of the deep mantle and insight …

Magnesium isotopic fractionation during basalt differentiation is commonly thought to be
negligible at current levels of analytical precision. However, Mg isotopic variation of∼ …

The geochemistry of global mantle melts suggests that both mid-ocean ridge basalts
(MORB) and ocean island basalts (OIB) sample lithological and temperature heterogeneities …

Mid-ocean ridge basalts (MORB) reveal large mantle compositional heterogeneity, whose
origin remains debated. Here we present a systematic study of molybdenum isotopes on …
