摘　　要：从区域变质、岩浆作用、构造作用等方面,对丹凤北部晶质石墨矿床的控矿条件进行了深入分析,认为丹凤北部晶质石墨矿床成因为区域变质型,并提出了区域变质+花岗“热穹”叠加变质改造+构造改造的成矿模式.进一步指出了瓦窑沟、回头山、波风岭一带为寻找石墨的远景区.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.
