Elena-Marie Rogmann et al.
The aluminous calcium-ferrite type phase (CF) and new aluminous phase (NAL) are thought to hold the excess alumina produced by the decomposition of garnet in MORB compositions in the lower mantle. The respective stabilities of CF and NAL in...
Oxide-silicate petrology and geochemistry of subducted hydrous ultramafic rocks beyond antigorite dehydration (Central Alps, Switzerland) [0.03%]

Joana Filipa Vieira Duarte et al.
Oxide minerals contained in ultramafic rocks are useful tools to assess the redox conditions of the rock and fluids liberated upon progressive serpentinite dehydration during subduction, as these minerals contain a relevant redox-sensitive ...
Alkaline magmas in shallow arc plutonic roots: a field and experimental investigation of hydrous cumulate melting in the southern Adamello batholith [0.03%]
亚当勒洛花岗岩体南部浅弧侵入根部的碱性火成岩:含水凝结物熔化的野外和实验研究

Manuel Pimenta Silva et al.
Despite the first-order importance of crystallisation-differentiation for arc magma evolution, several other processes contribute to their compositional diversity. Among them is the remelting of partly crystallised magmas, also known as cum...
Trace element partitioning in basaltic systems as a function of oxygen fugacity [0.03%]

Michelle L Foley et al.
The volcanic rocks of the Chon Aike Silicic Large Igneous Province (CASP) are recognized as magmas dominantly produced by crustal anatexis. Investigating the zircon of the CASP provides an opportunity to gain further insight into geochemica...
Tracing fluid infiltration into oceanic crust up to ultra-high-pressure conditions [0.03%]

Daniela Rubatto,Morgan Williams,Thorsten Andreas Markmann et al.
Daniela Rubatto et al.
Fluid-rock interaction within the altered oceanic crust and across the slab-mantle boundary during subduction facilitates element transfer, but the dynamics of fluid transport and fluid-rock exchange during upward fluid migration are still ...
Decoding the nanoscale porosity in serpentinites from multidimensional electron microscopy and discrete element modelling [0.03%]
基于多维电子显微镜和离散元素模拟解译蛇纹岩中的纳米级孔隙结构
