Abstract
Vermiculite mineralization in the Gopalpura area, Karnataka in the Archean supracrustal rocks of the Sargur Group occurs as discontinuous lenses and pockets within the ultramafic rock and at the contact with acid intrusives. Detailed mineralogy as studied using microscopy, X-Ray diffraction, infrared spectroscopy, differential thermal analyses, and electron microprobe analyses are presented. The probable origin of the vermiculite from biotite through hydrobiotite is discussed.
Keywords
