| 中文摘要: |
| 利用DGSInfo软件对湘南坪宝地区1:5万水系沉积物地球化学数据进行元素相关分析、R聚类分析和因子分析，确定元素的共生组合关系；采用原始数据取对数剔除异点使元素含量呈正态分布，以高出背景值的1-2倍标准差为异常下限值，制作出各元素异常图和组合异常图；在GIS支持下，结合区内成矿地质条件对组合异常区进行综合分析，圈定了麦子坪-金子岗-梧桐、禾茂村-马鞍岭两个铅锌多金属矿找矿靶区。 |
| 英文摘要: |
| By use of the DGSInfo software, analysis is conducted to 1:50000 stream sediment geochemistry data in the Pingbao area, southern Hunan Province, involving element correlation, R clustering and factors. The purpose is to determine the combination of symbiosis among elements. By taking?the?logarithm with original data to eliminate singular points and to make the element contents be a normal distribution, this work prepares the anomaly chart and the integrated anomaly chart for every element with the threshold 1-2 times the background value. Supported by GIS, coupled with comprehensive analysis of the combination?anomaly areas to the ore-forming geological conditions in this region, this work determines two prospecting targets of lead-zinc multiple metal deposits, i.e. the Maizi Ping-Jingzigang-Wutong and Hemaochun-Ma’anling areas. |
