| 摘 要： | 地球化学测量成果被广泛而成熟地运用在矿产勘查工作中,为明确张家口崇礼区北部成矿、找矿的地球化学指示信息,对该区水系沉积物测量及异常查证成果进行了综合分析。通过计算元素富集系数和变异系数、开展R型聚类分析、统计化探异常区岩石的地质年代、对比该区化探异常及已知矿床与典型矿床的成矿要素,从而推断了该区找矿主攻元素为Ag、Pb、Zn、Mo、Cd,且Ag、Pb、Zn和Mo、W 2组元素分别具有共伴生关系,指出该区化探异常主要受燕山期岩浆热液控制。综合分析认为,本区找矿模型为蔡家营式次火山-热液型多金属矿床,具有寻找次火山-热液型Ag、Pb、Zn、Mo多金属矿床的潜力。

| Abstract: | Geochemical survey results have been used widely and maturely in mineral exploration work. In order to ascertain the geochemical indication information of mineralization and prospecting in the north of Chongli, the authors made a comprehensive analysis of the stream sediment survey and the anomaly verification results in this area. Through calculating element enrichment coefficient and variation coefficient, analyzing R-type cluster, counting the rocks geological ages in the geochemical prospecting anomaly area, and comparing the mineralization factors of geochemical prospecting anomaly, the deposits known and the typical deposits, the authors deduced that the main prospecting elements in this area are Ag, Pb, Zn, Mo and Cd, and the two element groups (Ag, Pb, Zn and Mo, W) have co-associated relationship respectively. And they pointed out that the geochemical prospecting anomaly in the area is mainly controlled by magmatic hydrothermal fluid of Yanshanian. After comprehensive analysis, the authors considered that the prospecting model in this area is the sub-volcanic-hydrothermal polymetallic deposit as Caijiaying deposit, and there is potential to find sub-volcanic-hydrothermal Ag, Pb, Zn, Mo polymetallic deposits in this area. |
