| 摘 要： | 通过对黑龙江省新林-塔源地区1∶5万水系沉积物测量数据的统计分析,结合多学科知识,对研究区Au、Ag、As、Sb、Bi、Cu、Pb、Zn、Mo、W、Cr、Ni、Hg 13种元素的平均值、标准离差、变异系数、相关性和元素空间分布情况等各项地球化学参数特征进行因子分析及聚类分析,总结出各元素的地球化学分布特征及地质意义。通过对研究区典型矿床的综合研究,总结出区域成矿地质和地球化学条件,结合单元素异常和组合异常的解释评价,最终认为矿集区北部有找到表生铅锌多金属矿的可能,而南部是寻找隐伏铅锌多金属矿的有利地段。

| Abstract: | Through statistical analysis of the 1∶50 000 stream sediment survey data of Xinlin-Tayuan area, and using multidisciplinary knowledge, the authors did factor analysis and dustering analysis of the average value, standard deviation, variation coefficient, correlation of geochemical parameters and elements spatial distribution characteristics of Au, Ag, As, Sb, Bi, Cu, Pb, Zn, Mo, W, Cr, Ni, Hg. The geochemical distribution of the elements and geological significance were summarized. Via comprehensive research on typical deposit of the study area, the authors also summarized the regional metallogenic geological and geochemical conditions. Combined with the interpretation of single-element anomalies and combination anomalies, the authors supposed that it was possible to find supergene lead-zinc polymetallic ore deposits in the northern part of the ore gathering area, while the southern part was a favorable area for concealed lead-zinc polymetallic ore. |
