Mineralogy and geochemistry of hydrothermal kaolins from the Adelita mine, Patagonia (Argentina); Relation to other mineralization in the area
(Mineralogical Soc, 2012-03)
The kaolin deposit at the Adelita mine, located in the province of Río Negro (Patagonia, Argentina), was studied. Petrographic studies on thin sections and chemical analyses of major, minor and trace elements on bulk samples ...
Genesis and mining potential of kaolin deposits in Patagonia (Argentina)
(Elsevier Science, 2016-10)
Kaolin occurs in Patagonia as residual (weathering or hydrothermal) deposits at the surface of an extended Jurassic rhyolite province or in the upper sedimentary Cretaceous or Danian–Paleocene layers. On the same paleogeographic ...
Geochemistry of Hydrothermal Alteration in Volcanic Rocks
(IntechOpen, 2012)
Minerals where a hydrothermal fluid delivers the chemical reactants and removes the aqueous reaction products. An understanding of hydrothermal alteration is of value because it provides insights into the chemical attributes ...
Genesis of the La Espingarda kaolin deposit in Patagonia
(Elsevier Science, 2010-02)
The La Espingarda kaolin deposit was formed by "in situ" alteration of sub-alkaline rhyolites belonging to the Jurassic Marifil Formation. Three altered volcanic lithofacies were identified: a porphyric biotitic ignimbrite ...
Cr(III) exchange on zeolites obtained from kaolin and natural mordenite
(ELSEVIER, 2006-01-21)
Zeolites with high Cr(III) exchange capacity were synthesized from kaolin and natural mordenite. The intermediate phases and final products were characterized by X-ray diffraction, FTIR spectroscopy, scanning electron ...
