1968年,我分队在伟大的无产阶级文化大革命的推动下,在收集分析前人资料的基础上,利用化探次生晕对太平铅锌矿点进行了评价,取得了较好的效果.根据实地踏勘和成矿地质条件分析,开展了2.4平方公里(测网100×20米)的次生晕工作,圈出两个铅异常.在其中的一个低值异常区经过井探验证,发现了铅锌矿体.现将化探次生晕找广效果概述如下.一、地质-地球化学特征(图1)1.地质概况本区处于尖峰岭穹窿、九嶷山穹窿和香花蛉穹窿之间的挤压脆弱带中,属新-嘉-兰锑汞铅锌矿带的南端,南北断裂带与北西西断裂带的交叉部位.区内生露地层见表1,未见火成岩活动,褶皱、断裂构造亦不发育.本区见两组断裂:一组为逆断层或逆掩断层,走向北西-南东,倾向北东,向南东收敛,
In 1968, under the impetus of the great Great Proletarian Cultural Revolution, our unit collected and analyzed the data of the predecessors and used the secondary halo of geochemical exploration to evaluate the lead-zinc mine in Taiping and achieved good results. According to Field reconnaissance and analysis of metallogenic geological conditions, carried out a secondary halo work of 2.4 square kilometers (measuring 100 × 20 meters), ringing two lead anomalies.One of the low anomalous regions after well exploration proved that Pb-Zn ore bodies. Now the second generation of geophysical exploration results are summarized as follows. First, the geochemical - geochemical characteristics (1) 1. Geological Overview This area is located in Jianfengling dome, between the Jiuyishan dome and Fragrant dome , The southern part of the Xin-Jia-Lan-stibumite-Pb-Zn ore belt and the intersection of the North-South fault zone and the North-West Xishan fault zone are shown in Table 1. There are no igneous activities, folds, There are two sets of faults in this area: one is reverse fault or reverse overthrust, heading northwest-south eastward, easterly eastward and converging to the south east,
