Abstract

In order to grasp the geological characteristics, the occurrence mode of ore body and development potential of Bophi Vum chromite mineralized zone in northwestern Myanmar, Korea Institute of Geoscience and Mineral Resources(KIGAM) and Department of Geological Survey and Mineral Exploration(DGSE) carried out joint exploration targeting on the $6km^2$ areas within the mineralized zone. Chromitites occur as a major Cr-ore body in the Bophi Vum area, and are enveloped by dunitic peridotites. As a result of geological survey, the geological map of Bophi Vum was drawn in the scale of 1:1,000, and we discovered that the chromitite ores are mainly distributed at the elevation range between 200 and 400 m. The soil geochemistry was conducted by collecting total 114 soil samples in the interval of 50 m after pitting ground surface under 0.7-1 m. Geochemical anomaly maps of Cr, Ni, Fe, and Mn were prepared by ICP-AES.
