Isotopic and geothermobarometric characterisation of metasedimentary rocks from the central Araçuaí-Ribeira orogenic system and its eastern basement: geotectonic implications
(Universidade Federal de Minas GeraisUFMG, 2017-10-10)
The Araçuaí-Ribeira orogenic system (AROS) located in south eastern Brazil comprises a wealth of lithologies, which reflect the geotectonic evolution of the region since the Precambrian. Demonstrably two large-scale orogenic ...
