APPLICATION OF NATURAL ELECTRIC FIELD METHOD IN THE EXPLORATION OF GRAPHITE DEPOSIT IN THE SANTONGGOU OREFIELD, QINGHAI PROVINCE

The Santonggou area in Dulan County, Qinghai Province, has good metallogenic conditions for graphite deposit, with a few clues for graphite mineralization. By the geophysical survey with natural electric field method, several abnormal zones are delineated, which supplies a well understanding to the distribution and mineralization of graphite orebodies in the area.
