High pressure and temperature (PT) experimental charges are valuable systems composed of minerals, often with quenched melt and/or fluid, synthesized to inform petrological processes deep within Earth. We explored the utility phase mapping for analysis 5 GPa partial melting experiments peridotite. further developed an open-source software workflow generate maps, which is scanning electron microscope (SEM) instrument agnostic. Phase maps were constructed offline, combining high-quality...
Mantle xenoliths usually represent fragments derived from the depleted and degassed lithospheric mantle with 3He/4He isotope ratios (6 ± 1 RA) lower than those of mid-ocean ridge basalts (8 RA). Otherwise, oceanic islands related to hotspots often have high (>10 RA), suggesting a deep pristine undegassed source. Here we present striking high-3He/4He component (up 27.68 recorded by spinel-facies Patagonia. Remarkably, highest were found in long-lived trans-lithospheric suture zone...
This study provides new information on the deformation, metamorphism, and tectonic setting of metavolcanic rocks southern portion Porongos Complex, Brazil. The structural analysis enabled identification three deformational phases, formed under ductile to semi-ductile conditions. D1 progressed through deformation partitioning, comprising closed isoclinal folds an axial plane foliation. Then, simple shear prevailed, resulting in folds, sigma-type porphyroclasts, foliation transposition,...
