An assessment of the rare metal potential of the granitoids of Siwana, Jalor, Jhunjhunu and Tosham, North Western Peninsular India

The rare metal contents of the plutons of Siwana, Jalor, Jhunjhunu and Tosham have been assessed. The peraluminous Tosham and Jhunjhunu granites are of high mineral potential, the peralkaline Siwana granites are also of high mineral potential whereas the metaluminous to peraluminous Jalor granites a...

Description
Summary:The rare metal contents of the plutons of Siwana, Jalor, Jhunjhunu and Tosham have been assessed. The peraluminous Tosham and Jhunjhunu granites are of high mineral potential, the peralkaline Siwana granites are also of high mineral potential whereas the metaluminous to peraluminous Jalor granites are of low mineral potential. According to the extant petrological, mineralogical and geochemical criteria, the Siwana granites are classified as rare metal granitoid of 'agpaitic' type, the Tosham and Jhunjhunu granites as 'plumasitic' type and the Jalor granites as 'calcic' type.
