Applications and limitations of thermobarometry in migmatites and granulites using as an example rocks of the Araçuaí Orogen in southern Bahia, including a discussion on the tectonic meaning of the current results

Brazilian Journal of Geology
In southern Bahia, there are outcrops of migmatites and granulites in the Jequitinhonha Complex, which is part of the northern portion of the Araçuaí Orogen.

Anticlockwise P–T Path of Granulites from the Monte Castelo Gabbro (Órdenes Complex, NW Spain) [PDF]

, 2003
The study of mafic and aluminous granulites from the Monte Castelo Gabbro (Órdenes Complex, NW Spain) reveals an anticlockwise P–T path that we interpret as related to the tectonothermal activity in a magmatic arc, probably an island arc.

Geochemical modelling of the tonalitic and trondhjemitic granulites from the Itabuna-Salvador-Curaçá Block, Bahia, Brazil

, 2011
International audienceThe studied tonalitic and trondhjemitic granulites are located in the SSE granulitic domain of the São Francisco craton, Bahia, Brazil, where they represent most of the southern part of the Archean and Paleoproterozoic Itabuna ...

Mineralogy and geochemistry of xenoliths in the Eocene volcanic rocks from southwest of Jandaq

Journal of Economic Geology, 2013
The Eocene volcanic rocks from the southwest of the Jandaq (Kuh-e-Godar-e-Siah, Central-East Iran micro-continent) are andesitic basalt and andesite in composition. These rocks contain xenoliths with granulitic mineralogy.

Seismic anisotropy from compositional banding in granulites from the deep magmatic arc of Fiordland, New Zealand

, 2017
We present calculated seismic velocities and anisotropies of mafic granulites and eclogites from the Cretaceous deep lower crust (∼40–65 km) of Fiordland, New Zealand.
