Description
Summary:The occurrence of gold, silver and platinum group of elements is reported from the Precambrian uraniferous quartz-pebble conglomerate (QPC) horizons at Mankarhachua area in the Precambrian Mankarhachua basin situated at the southwestern part of the Singhbhum–Orissa craton. Scanning electron micrographs show native gold grains and unidentified platy silver-bearing minerals. Chemical analysis of the host QPC samples shows significant abundances of gold and silver and anomalous content of platinum group elements. Platinum, ruthenium and rhodium dominate over palladium. This communication focuses on the gold and silver abundances, their distribution, hostrock characteristics and preliminary study on the control of mineralization.
