川西可尔因地区1∶5万水系沉积物测量异常评价及找矿预测

Anomaly Evaluation and Prospecting Prediction of 1∶ 50000 Stream Sediment Survey in Keeryin Area,Sichuan Province

以可尔因地区1∶5万水系沉积测量成果为基础,对该地区8种与稀有金属矿床密切相关的元素进行了R型聚类分析、因子分析。结果表明,该地区各元素间的相关性较好,主成矿元素为Li。各元素异常强度高,规模大,套合性好,主要分布在可尔因岩体外接触带。结合地质、物探成果,圈定了8处锂多金属矿找矿靶区。

Based on the results of the 1∶50 000 stream sediment survey in the Keeryin area,western Sichuan,the R-type cluster analysis and factor analysis were carried out for the 8 elements closely related to the rare metal deposits in this area.The study shows that the correlation between the elements is good,the main ore element is Lithium.The anomalies of the elements are high intensity,large scale,good registration,mainly produced in the external contact zone of Keeryin rock body.Combined with geological and geophysical results,8 lithium polymetallic prospecting targets were delineated.
