江西玉华山地区水系沉积物化探数据处理及找矿靶区划分

摘要

利用GeoExpl软件对江西省玉华山地区1∶50 000水系沉积物地球化学分析数据进行处理分析,运用多元地质统计分析方法对化探数据进行R聚类分析和因子分析,对分析结果制作单元素异常图和综合异常图,确定了元素异常分布及共生关系.在GIS支持下,结合地质背景,构造特点,地表矿化现象和岩体特征,对江西玉华山地区异常信息进行了综合评定,并指导异常区的成矿远景靶区预测.%In this research, software " GeoExpl" is used to process and analyze the data coming from the scale 1 : 50 000 stream sediment of geochemical of Jiangxi Yuhuashan. With the method of multiva-riate geo-statistic analysis, R-cluster analysis and initial factor matrix can be figured out from geochemical data. And the results of analysis can be used to produce single-element and integrated a-nomaly map to fix the elements of abnormal distribution, symbiotic relationship and genetic mechanism. In order to instruct the prediction of metallogenic, with the tool of GIS, and taken the different elements of geological background, the structure characteristics, the surface mineralization and rock mass characteristics into consideration, this research is conducted to make a com-rnprehensive assessment of the anomaly information of Jiangxi Yuhuashan.
