摘要
在分析青海省哈图地区1∶5万水系沉积物测量19种元素的富集和离散特征基础上,探讨了元素的共生组合、富集规律以及元素异常特征,指出了研究区主要成矿元素为W,Au,Ni,Bi,Sb,Ag,Pb,Mo,Cr,As,Cu;并圈出3个成矿远景区。在找矿远景区内开展简单的查证工作,新发现了多处多金属矿(化)点和矿化信息点,证明了该次水系沉积物测量综合异常的真实存在,为今后在该地区部署找矿工作指明了方向。
Based on analyzing enrichment and dispersion ol 19 kinds ol elements gained from stream sediment sur-vey with the scale ol 1 ：50000 in Hatu area in Qinghai province,the paragenetic association ol elements, enrich-ment regularity and element anomaly have been studied. 1t is pointed out that major ore-forming elements are W , Au, Ni, Bi, Sb, Ag, Pb, Mo,Cr,As and Cu. Three ore-lorming prospecting areas have been circled as w e ll. Simple verilication work has been carried out in prospecting area,many polymetallic mineralization points and in lo r- mation have been newly discovered. 1t is proved that comprehensive anomaly ol stream sediment survey is really ex-isted. The direction ol exploration work in this area has been pointed out .
