摘要
通过区域地质的研究,分析了头滩子地区的土壤金异常晕,该区土壤晕分布与构造展布方向一致,金异常晕对地层的选择性不明显。指出了构造、热液、地层岩性三位一体控制着金的矿化与成矿,特别是断裂构造是金矿化的必要条件。
The regional geology in Toutanzi area of Huixian County is introduced. The soil geochemical survey of scale 1：25 000 determined 11 pieces of gold anomaly of soil, which show that the distribution of soil halos is consistent with the spreading direction of structures, the selectivity of halos to strata is not obvious. The study reveals that the gold mineralization is controlled by the trinity of structures, hydrothermal fluids and stratagraphic lithology, particularly, the fault is necessary.
