青海哈图地区水系沉积物地球化学特征及找矿方

Prospecting Direction and Geochemical Characteristics of Stream Sediments in Hatu Area in Qinghai Province

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。

Abstract:

Based on analyzing enrichment and dispersion of 19 kinds of elements gained from stream sediment survey with the scale of 1∶50000 in Hatu area in Qinghai province, the paragenetic association of elements, enrichment regularity and element anomaly have been studied. It is pointed out that major ore-forming elements are W, Au, Ni, Bi, Sb, Ag, Pb, Mo, Cr, As and Cu. Three ore-forming prospecting areas have been circled as well. Simple verification work has been carried out in prospecting area, many polymetallic mineralization points and information have been newly discovered. It is proved that comprehensive anomaly of stream sediment survey is really existed. The direction of exploration work in this area has been pointed out .
