| 摘 要： | 对小石人金矿区进行的实验性地质测量剖面显示, 土壤地球化学法、电阻率法、激发极化法和能谱测量法等能指示矿化蚀变分带。土壤地球化学测量中: Au、Ag、As、Cu、Pb、Zn、Co、Ni、Bi、 Hg和V等元素的地球化学浓集趋势有效指示出矿化集中区和蚀变带, Mn元素还可做为金矿化区的边界指示元素。地球物理测量结果显示两种信息模式: ① 高阻、高极化、相对低磁、低K和低总计数率在空间上对应硅化蚀变带地段; ②低阻、低极化、相对高磁、高K和高总计数率对应于石英斑岩侵入体地段。综合信息推断出硅化蚀变带出现在石英斑岩侵入体两侧, 经过工程控制在石英斑岩南北两侧发现两条矿带, 证实找矿模型正确, 并发现金矿脉两条, 计算储量为5.2 t。

| Abstract: | The measurements of experimental profiles in Xiaoshiren gold area show that the methods of soil geochemitry, resistivity, induced polarization and energy spectrometry have the ability to direct the alterative zones of mineralization. By soil geochemicalmethed, the elements of Au, Ag, As, Cu, Pb, Zn, Co, Ni, B i, Hg and V can indicate mineralization concentration and alterative zones effectively, and Mn can also act as the indicator for showing the border of gold deposit. Geophysical method displays two information models: ① high resistivity, high polarization, low K, relative low magnetism and low total counts, which correspond to silicic alterative zones; ② low resistivity, low polarization, high K, relative high magnetism and high total counts, which correspond to quartz porphyry intrusive body. Based on synthetic information, the authors infer the silicic alterative zones locate in both sides of quartz porphyry intrusive body. Two gold deposit veins have been found through engineering test in both northern and southern sides of quartz porphyry intrusive body, which accords with the inference, and the estimation of ore reserves is about 5.2 t. |
