Fluid-induced metamorphism and anatexis of refractory Ni-Co-Cu sulphides in subduction-related rocks [PDF]
E3S Web of Conferences, 2019 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 ...

Evolution of migmatitic granulite complexes: Implications from Lapland Granulite Belt, Part I: Metamorphic geology [PDF]
Bulletin of the Geological Society of Finland, 2006 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.

On the issue of establishing the type of coal seams by «reduction» («oxidation») of fossil coals
Технічна інженерія, 2022 The yield of volatile substances during the thermal decomposition of coals and the oxygen content in the organic mass do not unambiguously characterize both the types of coals according to the expected reduction, and the manifestations of the hazardous ...

U-Pb zircon geochronology of selected Archaean migmatites in eastern Finland [PDF]
Bulletin of the Geological Society of Finland, 2007 U-Pb SIMS data on eight samples (four mesosome-leucosome pairs) from migmatites in gneiss complexes are presented from the western part of the Archaean Karelian craton, eastern Finland. Most zircon grains in the mesosomes yield ages between 2.84 Ga and 2.
