Altered oceanic crust (AOC) plays a critical role in geochemical recycling in subduction
zones. However, identifying contributions of subducted AOC to arc magmas remains a …

Titanium (Ti) typically exhibits low mobility in geologic fluids due to the low aqueous
solubility of common (Fe-) Ti oxide minerals. Consequently, Ti isotope variations (δ 49/47 Ti …

Sanukitoids are unique Archean and early Proterozoic igneous rocks. They contain high
amounts of Mg, Ni and Cr, showing they are mantle-derived melts, while they are also …

Rubidium (Rb) is a strongly incompatible and highly fluid-mobile element and Rb isotopes
have the potential to track subducted material recycling to the mantle source of arc magmas …

Mantle metasomatism, which affects the geochemical and lithological properties of the Earth,
is crucial to the evolution and modification of the Earth's interior. Variations in chemical proxy …

俯冲带是连接地表和深部地球之间物质循环的关键纽带. 目前对俯冲带演化过程及内部物质传递
机制认识还不够清晰, 其中一个难点在于缺乏记录早期弧岩浆过程的载体 …

The chemical and isotopic composition of gases emitted by subduction zone volcanoes can
provide insights into the origin of magmatic volatiles. In volcanic arcs, magmatic volatiles can …

Subduction zones are the key link between the surface and the deep earth. The evolution of
subduction zones and the internal material transfer mechanism are not clear enough. One of …
