摘要
为解决大兴安岭塔源地区寻找隐伏矿问题,在矿区内开展地电化学找矿研究。对地电提取的Cu、Pb、Zn、Ag、Au等15种元素的数据进行因子分析,并利用异常衬度法对主成矿元素及因子分析所提取的四类因子组合(即F1-Cr、Mo、Ag、Pb、Bi;F2-W、Hg、Au;F3-Cu、Zn;F4-Li、Co、Ni、As、Sb)所形成的新数据集进行数据处理,结果表明:F3因子组合为主成矿因子,为勘查区有利成矿地段。根据异常衬值:KCu>1.36、KZn>1.64、F1>8.33、F2>5.79、F3>1.92、F4>7.01划分异常区,并结合地电提取主成矿元素及因子组合异常特征,圈出3处具有找矿前景的靶区,认为Ⅰ-1靶区成矿潜力较大。
Geoelectrochemical prospecting and prediction research was carried out in prospecting and prediction for concealed deposit in Tayuan area of Da Hinggan Mountains. The geoelectrochemical data of 15 elements including Cu、Pb、Zn、Ag、Au etc are analyzed by factor analysis. Anomaly contrast method is used to process the new data sets formed by the main metallogenic elements and four kinds of factor combinations(F1-Cr, Mo, Ag, Pb, Bi;F2-W, Hg, Au;F3-Cu, Zn;F4-Li, Co, Ni, As, Sb)extracted from factor analysis. The results show that the combination of F3 factors is the main metallogenic factor and the favorable metallogenic area. According to the abnormal contrast values: KCu>1.36, KZn> 1.64, F1> 8.33, F2> 5.79, F3> 1.92, F4> 7.01, the abnormal regions are divided. Combined with the anomaly characteristics of main ore-forming elements by geoelectrochemistry and factor combination,three target areas with prospecting prospects are delineated.It is considered that the metallogenic potential of I-1 target area is prospecting.
