摘要
四川阿坝州某晶质石墨矿发现于龙门山构造带中段的元古界黄水河群黄铜尖子组三段(Pt_(Hh)~3),变质岩系中,矿体呈层状、似层状赋存于石墨片岩、石墨石英片岩内,矿体受地层层位控制明显,为沉积变质型石墨矿床。龙门山构造带中元古界黄水河群黄铜尖子组三段之含矿层位是主要的找矿目标。
The cry s tall ine graphite deposit in A b a,Sichuan is discovered in Proterozoic Huangsliuihe Group Hu an- gtong＇ianzi Formation Member 3 （ PtHh ） metamorphic rock series in the m id dle section o f Longmenshan tectonic zone. The ore body is in the graphite s c h is t, graphite quartz s c h is t, which is controlled clear by the bed horizon. It is a sedimentary metamorphic graphite deposit. The main prospecting target is the ore-bearing bed o f Proterozoic Huangsliuihe Group Hu an gton gia nz i Formation Member 3 in Longmenshan tectonic zone.
