Evolution of migmatitic granulite complexes: Implications from Lapland Granulite Belt, Part II: Isotopic dating [PDF]
The migmatitic metapelites of the Lapland granulite belt (LGB) in the NE part of the Fennoscandian Shield represent an arc-related greywacke basin metamorphosed in the granulite facies. Detrital zircons from migmatitic metapelites are derived from 1.94 −

Constraining the Protoliths of the Apollo Granulite Suite [PDF]
The Apollo granulite suite represents the metamorphosed products of impact-contaminated polymict and monomict lunar breccias. We combine bulk and mineral major and trace element systematics with noble gas isotopes to constrain the highland lithologies ...

Granulite-facies metamorphism at ca. 570-580 Ma in the Porangatu Granulite Complex, central Brazil : implications for the evolution of the transbrasiliano Lineament [PDF]
O Complexo Granulítico Porangatu está exposto na porção central da Província Tocantins, do Neoproterozoico, no centro do Brasil, ao longo da fronteira entre o Cinturão Brasília, a leste, e o Cinturão Araguaia, a oeste. Esta região faz parte do sistema de

RETROGRESSION OF ORTHOPYROXENE – BEARING CHARNOCKITIC GNEISS AROUND IKERAM-IBARAM AKOKO, SOUTHWESTERN NIGERIA [PDF]
This paper presents the petrography and mineral chemistry of charnockitic gneisses exposed at Ikeram-Ibaram within the Precambrian Basement Complex of southwestern Nigeria. Quartz, plagioclase, perthite, amphibole, biotite and orthopyroxene are essential

Evolution of migmatitic granulite complexes: Implications from Lapland Granulite Belt, Part I: Metamorphic geology [PDF]
The Palaeoproterozoic Lapland granulite belt was juxtaposed between Archaean and Proterozoic terrains in the NE part of the Fennoscandian Shield concurrently with the accretion of Svecofennian arc complexes at ~1.9 Ga.

Fluid-induced metamorphism and anatexis of refractory Ni-Co-Cu sulphides in subduction-related rocks [PDF]
The role of metamorphism on refractory sulfides is not well constrained. Although experiments have displayed the effectiveness of high grade metamorphism, namely granulite facies metamorphism, on sulfide anatexis, its role in the presence of other ...

MECHANICAL PROPERTIES OF GRANULITE FROM HORNÍ BORY IN BOHEMIAN MASSIF
Granulite represents one of the favourite rock types for the construction of an underground nuclear waste repository in the Czech Republic. Granulite from the Bohemian Massif (locality Horní Bory) was investigated in this study, with a special focus on ...

For the first time in the sixty years since the synthesis of stishovite, we report unambiguous evidence of stishovite formed in the deep Earth. A minimum pressure of about 7.5 GPa at 1000 °C is necessary for the formation of stishovite, corresponding to ...
