辽宁虎山-永甸地区水系沉积物测量异常特征及成矿预测

CHARACTERISTICS OF ANOMALY BY STREAM SEDIMENT SURVEY AND METALLOGENIC ANALYSIS OF HUSHAN-YONGDIAN AREA IN LIAONING PROVINCE

摘要: 对虎山-永甸地区1：5万水系沉积物资料处理结果显示：元素富集程度较高，Au、As、Bi变异系数较大.根据各元素的地球化学特征圈定了Au、Ag、Cu、Pb、Zn、Mo、As、Sb、Bi等单元素异常及7处多元素综合异常，揭示了区内异常的分布特征，评价了异常的找矿意义.进一步依据综合异常特征和地质信息划分出最佳成矿预测区4处，即太平湾-长甸河口预测区、古楼子-金坑预测区、车道岭-南碑沟预测区和长甸-李家沟预测区.

Abstract: The 1:50000 stream sediment survey in Hushan-Yongdian area, Liaoning Province, reveals that the anomalous elements are highly concentrated, of which Au, As and Bi show large variation coefficients. Based on the geochemical characteristics of each element, the authors delineate the single element anomalies of Au, Ag, Cu, Pb, Zn, Mo, As, Sb and Bi, as well as seven integrated anomalies of multi-elements. With the distribution characteristics of anomalies in this area, the prospecting significance of the anomalies are evaluated. Furthermore, four best metallogenic forecasted areas are delineated.
