Abstract: Chrome chlorite associated with the chromite deposits of the Nuggihalli schist belt has been investigated by detailed mineralogical, chemical, X-ray diffraction, differential thermal and i.r. spectral analyses. Following the nomenclature of Lapham (1958) it is inferred that the chromium of the chrome chlorite is in the tetrahedral position and therefore the mineral is kotschubeite and not kaemmererite as suggested by earlier workers.
