DOI: 10.1016/j.gsf.2020.11.010
Abstract: Abstract Spiral garnet porphyroblasts are known to record lengthy periods of deformation and metamorphism by preserving single or multiple FIAs (Foliation Intersection Axis) formed normal to tectonic shortening directions. Thanks to technological advances in X-ray… read more here.

DOI: 10.1016/j.jseaes.2019.104087
Abstract: Abstract Knowing the protoliths of eclogites is important to understanding the nature and process of orogeny. It has been debated whether the eclogites of the Marun-Keu complex, Russian Polar Urals represent a fragment of metamorphosed… read more here.

DOI: 10.1016/j.lithos.2017.12.008
Abstract: Abstract The North Shahrekord Metamorphic Complex (NSMC) of the central Sanandaj-Sirjan Zone (SaSZ) consists of metagranitoid bodies, which were metamorphosed within high pressure-low temperature conditions. Whole rock chemistry shows relatively high amounts of SiO2 (65–77 wt%)… read more here.

DOI: 10.1016/j.lithos.2019.105273
Abstract: Abstract The South Tianshan orogen (northwest China) comprises a thick volcanoclastic HP-UHP metamorphic belt, the Akeyazi (high-pressure) metamorphic complex (AMC), exhibiting well-preserved eclogite- and blueschist-facies rocks and pervasive deformation throughout all units. In order to… read more here.

DOI: 10.1080/00206814.2018.1443403
Abstract: ABSTRACT Mixtures of melt and residue in a high-T metamorphic complex have a lower density and viscosity than the surrounding host crust, and the mixtures should ascend due to buoyancy. The mixtures are recognized as… read more here.
