TL;DR: In this article, a large-scale mantle low δ26Mg anomaly in eastern China has been delineated, suggesting the contribution of sedimentary carbonates recycled into the upper mantle, but limited into the lower mantle.

TL;DR: A petrological and geochemical study of the basalt clasts from the Procellarum KREEP Terrane (PKT) returned by the Chang'e-5 mission is presented in this paper.

TL;DR: This article presented stable Mg isotopic data for Cenozoic potassic basalts from Wudalianchi and Erkeshan in northeastern China to determine the interactions between upwelling carbonated asthenosphere and enriched lithospheric mantle.

TL;DR: In this paper, high-precision stable Mg isotopes of arc-like volcanic rocks from Tengchong, Southwestern China, have been investigated, revealing a new carbon cycle in which Mg-rich carbonate -dolomite -can be dissolved by supercritical liquids and subducted into a deep mantle wedge to depths of 120 to 300 km in the oceanic subduction zone.

TL;DR: In this article, the authors determine equilibrium Fe isotope fractionation factors between several common rock-forming minerals using a comparative approach involving three independent methods: (i) isotopic analyses of natural minerals from a metapelite from Mt. Moosilauke, New Hampshire, for which equilibration temperature and pressure are well constrained to be near the aluminosilicate triple point (T
