Geology and lithogeochemistry of migmatites, charnockites and granulites of the Guaxupe Complex, Sao Joao da Boa Vista region, Sao Paulo State, Brazil
(Soc Brasileira Geologia, 2013-06-01)
This paper presents new geochemical and petrological data from the southern portion of the Guaxupe Complex. The research area is characterized by the occurrence of migmatites and an intrusive body of charnockitic granite ...
Palaeoproterozoic dome-forming structures related to granulite-facies metamorphism, Jequi´e block, Bahia, Brazil: petrogenetic approaches
(2004)
Dome structures in the São Francisco craton (Northeast Brazil), have been identified in the regions of Brejões and Santa
Inês within the granulitic Jequié block. Domes are mainly composed of CH6 charnockites, which intrude ...

The link between partial melting, granitization and granulite development in central Ribeira Fold Belt, SE Brazil: New evidence from elemental and Sr-Nd isotopic geochemistry
(PERGAMON-ELSEVIER SCIENCE LTD, 2011)
Elemental and Sr-Nd isotopic data on metatexites, diatexites, orthogneisses and charnockites from the central Ribeira Fold Belt indicate that they are LILE-enriched weakly peraluminous granodiorites. Harker and Th-Hf-La ...
