A simple mechanism for mid-crustal shear zones to record surface-derived fluid signatures
Ion microprobe analyses of garnet porphyroblasts from three separate splays of the mid-crustal Walter-Outalpa shear zone, Curnamona Province, South Australia, indicate homogeneous δ18O values of <3‰. Integrated Lu-Hf geochronology and electron microprobe compositional mapping demonstrate that clo...
