Origins of high δ18O in 3.7–3.6 Ga crust: A zircon and garnet record in Isua clastic metasedimentary rocks [PDF]
, 2020 Elevated δ18O is used as a marker for the presence of continents and surficial alteration in the Eoarchean and Hadean. This study establishes a timeline for δ18O enrichment in Eoarchean metasedimentary rocks of the Isua supracrustal belt in Greenland ...

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 ...
