摘　　要：研究区地处青藏高原的腹地,大地构造单元属冈底斯-下察隅晚燕山-喜马拉雅期岩浆弧带,其北为班公-怒江结合带,南部为冈底斯南缘弧前盆地带及雅鲁藏布江缝合带。研究区内中-新生代地层较发育,地质构造较为复杂,中、新生代岩浆活动十分强烈,侵入岩、火山岩均十分发育。以1∶5万打加错地区4幅区域地质调查取得的新找矿线索为基础,对打加错新发现的斑岩型铜矿的地质、岩石地球化学特征进行阐述,为研究该区域的斑岩型铜矿的成矿条件和成矿背景提供依据。The study area is located in the hinterland of Qinghai Tibet Plateau,Gangdise tectonic units of Yanshan-Himalaya-the next Chayu late magmatic arc zone,the north of Bangong-Nu River junction zone,southern Gangdese forearc basin zone and the southern margin of the Yarlung Zangbo Suture zone. The study area in the Mesozoic and Cenozoic strata are well developed,complex geological structure,in Cenozoic magmatic activities is very strong,intrusive rocks,volcano rock are very developed. By 1 ∶ 50000 dozen mistake area 4 regional geological survey obtained new clues for prospecting based on the wrong,newly discovered porphyry copper deposits, geochemical characteristics of porphyry copper deposits,provide the basis for the study of the regional metallogenic conditions and metallogenic background.
