The Querari Complex corresponds to the basement rocks from Uaupes Domain and represents one of least studied units in northwest Rio Negro Province, Amazonian Craton. In this paper, we present new field geology, petrographic, geochemical data deformed granites Complex. Based on our results, suggest differentiation into two magmatic facies. Pana-Pana Facies comprise mainly porphyritic syeno monzo...

The Belomorian Province of the Fennoscandian Shield exposes numerous Precambrian eclogites, which makes it significant for study early tectonic processes. age these eclogites has been discussed more than 15 years and regarded as either Archean or Paleoproterozoic. In Kuru-Vaara quarry within northern Province, eclogitic assemblage is preserved in concordant mafic boudins felsic gneisses a parti...

The basement of eastern Mexico comprises Grenvillian-age granulite-facies metamorphic rocks. Oaxacan Complex represents the largest outcrop belt this in Mexico. In work, southwestern garnets are studied from a petrographical, geochemical, and geothermobarometrical perspective for first time. display different grain sizes nucleated polyphase evolution. almandine end member proportion is similar ...

The Taku Schist, which is located in the north-east Peninsular Malaysia, characterized by its North-South oriented elongated body. It forms part of Indonesian orogenic build-up that was generated via convergence Sibumasu continental unit and Sukhothai Arc. Subsequent petrography analyses metasedimentary rocks sourced from Schist revealed their formation attributable to metamorphism greenschist ...

Abstract. Modern-style plate tectonics is characterised by the global operation of cold and deep subduction involving blueschist facies ultrahigh-pressure metamorphism. This has been a common process since Neoproterozoic, but couple studies indicate similar processes were active in Paleoproterozoic, at least on local scale. Particularly conspicuous are extreme conditions ∼ 7 GPa thermal gradien...

Abstract In this contribution, we present the stratigraphy of igneous and metamorphic rocks Taquetren Range, a sector located in southernmost margin North Patagonian Massif (42°42′00″ S - 69°30′00″ W). Its basement is composed newly defined “Lagunita Salada Igneous-Metamorphic Complex” (LSIMC), “Paso del Sapo Plutonic (PSPC) “Sierra de (STPC). The LSIMC comprises gneisses, schists, amphibolites...
