ORE-CONTROLLING CONDITIONS AND PROSPECTING POTENTIAL OF CRYSTALLINE GRAPHITE DEPOSITS IN NORTHERN DANFENG COUNTY, SHAANXI PROVINCE

The ore-controlling conditions of crystalline graphite deposits in northern Danfeng County are analyzed from the aspects of regional metamorphism, magmatism and tectonism. It is considered that the deposits are genetically regional metamorphic type, with the metallogenic model of regional metamorphism + granitic thermal dome superimposed by metamorphism + tectonic transformation. It is further pointed out that the areas of Wayaogou, Huitoushan and Bofengling are prospective for graphite prospecting.
