A GOLOGICAL NOTE ON THE COLD PANNING ACTIVITY IN THE KAPSI-LOHATTAR AREA, KOTRI LINEAR BELT. M.P.

摘要

The distribution pattern of gold panning activity by local gold panners along different streams of the Kapsi-Lohattar area of northern part of Bastar district is studied. From such study, the possible source rocks for gold is inferred. It is found that west of the Kotri river possible source rocks for gold are the two major quartz reef shear zones viz, the Dorde Kaddar Shear Zone and the Pachangi Shear Zone and also some locally present aresenopyrite bearing rhyolite and tufaceous layers. East of the Kotri river, possible source rocks for gold are the conglomerate units of the Patkasa Formation which forms an younger sedimentary cover over the volcano-sedimentary rock suite of the Kotri Supergroup. Gold present in this Formation could represent paleoplacer deposit. The BIF of the Latmarkarka Formation could also be a source.
