A spectrum of disequilibrium melting preserved in lava-hosted, partially melted crustal xenoliths from theWudalianchi volcanic field, NE China
(Elsevier, 2015)
Disequilibrium melting has been established as a common process occurring during crustal anatexis and thus demonstrates that crustal assimilation is not a closed system. Observations of extreme compositional heterogeneity ...
Age and origin of coeval TTG, I- and S-type granites in the Famatinian belt of NW Argentina
(Royal Society of Edinburgh, 2000-11)
Three granitoid types are recognised in the Famatinian magmatic belt of NW Argentina, based on lithology and new geochemical data: (a) A minor trondhjemite-tonalite- granodiorite (TTG) group, (b) a metaluminous I-type ...

P-T-t path reconstruction in a syn-deformational migmatization event along the north-central portion of Sierra de Comechingones, Córdoba, Argentina
(Pergamon-Elsevier Science Ltd, 2021-12)
The granulite-complexes of the Sierras de Córdoba, inside context of Sierras Pampeanas, expose the deeply-uplifted internal metamorphic zone of an early Cambrian orogen. One of the largest granulite-complexes in the ...
Reaction microtextures of monazite: Correlation between chemical and age domains in the Nazare Paulista migmatite, SE Brazil
(ELSEVIER SCIENCE BV, 2009)
Back-scattered imaging, X-ray element mapping and electron microprobe analyzer (EMPA) chemical dating reveal complex compositional and age zoning in monazite crystals from different layers and textural positions in a ...
