A Preliminary Geological Investigation of Sisakhan Base Metal Occurrence of Higher Himalayan Yamuna Valley, U.P.

Sisakhan base metal deposit is likely to be a workable mineral deposit in rather poorly mineralised Himalaya. The mineralised quartz vein contains mainly galena and small quantity of chalcopyrite and sphalerite. The mineralised vein is structurally controlled at the contact of chlorite schist and biotite schist and probably emplaced in the later part of Neogene as no evidence of deformation is found in the vein. The preliminary investigation suggests that the mineralisation took place in relatively dry and low temperature condition.
