Here we present a detailed investigation of high-grade granulite-facies rocks of the Mashan Complex from the Liumao area, Heilongjiang Province, China. This includes zircon U–Pb dating, petrological and geochemical analysis, geothermobarometry, phase equilibria modelling, and a P–T path. The ...
Decompression and high-temperature–low-pressure metamorphism in the exhumed floor of an extensional basin, Alboran Sea, western Mediterranean The cored rocks closely resemble high-grade metamorphic rocks in the adjacent Betic Cordillera of southern Spain, which yield early Miocene radiometric dates... ...
A combination of geological and isotopic-geochronological (K/Ar, 40Ar/39Ar, U-Pb-zircon methods) studies indicates that high-pressure-low-(in part, intermediate) temperature metamorphic rocks of both coherent complexes and inclusions in serpentinite melange were formed during Cretaceous and possibly to...

they have a long geological history during which these rocks were modified by varying degrees of tectonic activity and metamorphism ranging from low-grade (e.g., Johnson et al.2003; Rasmussen et al.2014,2016,2017; Mloszewska et al.2012) to high-grade (Klein1978,2005; Prasad et al.1982;...
