青藏高原东部宜墩弧汞同位素痕量岩浆混合及地壳-地幔相互作用数据

镁铁质和长英质熔体之间的岩浆混合在开放的岩浆过程中很普遍。然而，追踪不同端体的岩浆来源具有挑战性，因为不同端体的元素和同位素信息通常在岩浆相互作用过程中达到平衡。地幔和地壳储层显示出汞（Hg）同位素质量无关分馏的独特特征，使汞同位素成为追踪地幔和地壳衍生岩浆的新兴工具。 <p...

Magma mixing between mafic and felsic melts is widespread in open magmatic processes. However, tracing the magma sources of different endmembers is challenging, as the elemental and isotopic compositions of distinct endmembers typically achieve equilibrium during magmatic interactions. Mantle and crustal reservoirs display unique characteristics of mass-independent fractionation of mercury (Hg) isotopes, making Hg isotopes an emerging tool for tracing magmas derived from the mantle and crust.
