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 …

Intraplate basaltic volcanism commonly exhibits wide compositional ranges from silica-
undersaturated alkaline basalts to silica-saturated tholeiitic basalts. Possible mechanisms …

Mantle oxidation plays an essential role in volatile cycling between Earth's interior and
exterior. However, the conceivable oxidizer remains enigmatic and needs to be explored by …

Carbonate dissolution in subduction zones transfers surface carbon to the mantle and plays
an important role in regulating global carbon cycles through geologic time. Petrological …

We report the first zinc isotope data (expressed as δ 66 Zn relative to the JMC-Lyon
standard) for chromian spinels (Cr-spinels) and coexisting olivines in oceanic peridotites. All …

Mantle source heterogeneity of arc‐related magmas was traditionally thought to be
predominantly affected by slab‐derived components. However, the role of forearc …

In the past few years, zinc isotope systematics of basaltic magmas have been widely used
as novel proxies for terrestrial mantle heterogeneity induced by recycled crustal materials …

Ocean island basalts (OIBs) with Zn isotopic ratios higher than the normal mantle (δ 66 Zn=
0.17±0.08‰) or mid-ocean ridge basalts (MORBs; δ 66 Zn= 0.27±0.06‰) generally also …

To investigate the role of carbonate recycling in generating ultrapotassic magmatic rocks, we
carried out detailed Mgsingle bondZn isotope analyses of silica-saturated to silica …

Abstract Mid-Ocean Ridge Basalts (MORBs) from the South China Sea (SCS) have attracted
great attention from geologists in the past decade, but their petrogenesis still remains …
