Transitional High-Al to Intermediate-Cr Podiform Chromitites from Wadi Zikt (Khor Fakkan Block, United Arab Emirates): Evidence for Reactive Melt Percolation during Nascent Forearc Evolution

Abstract Podiform chromitites at Wadi Zikt in the Khor Fakkan Block of the United Arab Emirates constitute a previously undescribed occurrence within the mantle section of the Semail ophiolite. We combine field relations, electron-probe microanalysis, in situ LA–ICP–MS mineral an...

Reaction‐Gated Transient Permeability in Ductile Shear Zones

Abstract Ductile shear zones act as transient pathways for crustal fluids, yet the conditions under which their connected porosity becomes sufficient to conduct are not well constrained. We present a porosity balance in which connected porosity evolves under three competing proce...
