X-RAY DIFFERACTION ANALYSIS FOR THE INTERPRETATION OF CLAY MINERALS PARAGENESIS IN THE NEOGENE SEDIMENTS OF MANG AND VICINITY, SUB-HIMALAYAS, PAKISTAN [PDF]
Earth Science Malaysia, 2017 The Neogene sediments were interpreted to understand the clay mineral paragenesis in rocks using x-ray differaction technique. The process was conducted with an x-ray diffractometer, Anode = Cu (Cu Kᾳ = 1.541871 A ), Filter = Ni, Current = 15 mA and ...

Tectonics and mineralization in Sri Lanka [PDF]
Bulletin of the Geological Society of Finland, 1985 Over nine-tenths of Sri Lanka is underlain by Precambrian metasedimentary rocks, granitic gneisses and migmatites. The Highland Series (granulite facies), made up of typical metasedimentary rocks ‒ quartzites, marble, white granulites and granulitic ...

Parameterization and quantification of recharge in crystalline fractured bedrocks in Galicia-Costa (NW Spain) [PDF]
Hydrology and Earth System Sciences, 2012 Quantifying groundwater recharge in crystalline rocks presents great difficulties due to the high heterogeneity of the underground medium (mainly, due to heterogeneity in fracture network, which determines hydraulic parameters of the bedrock like ...

Geology and Lithogeochemistry of the Supracrustal Sequence and Interlayered Metabasites of NE Santos Dumont Region (MG) [PDF]
Anuário do Instituto de Geociências, 2017 The region near Santos Dumont town consists of a sequence of interlayered metabasic rocks and supracrustal gneisses. Two lithological units were individualized based on geological-structural mapping (1:50,000), petrography and lithogeochemistry: a ...

Isotope disequilibrium during partial melting of metasedimentary rocks
Geochimica et Cosmochimica Acta, 2019 Abstract The chemical composition of partial melts is buffered by the rock forming minerals that participate in the melting reactions and by the solubility of accessory phases in these melts. Both depend on the melting conditions. The chemical composition of restite depends on the restite mineralogy and may be highly variable.
