文章通过分析区域地质背景、简述锑矿地质特征,总结了口子下地区锑矿成矿地球化学特征,指出矿床赋存于中三叠统第三岩性段钙质砂岩、砂质板岩、粉砂岩中,矿体受地层、构造、热液蚀变控制明显,具有西秦岭区典型的低温热液成矿特征,锑土壤异常受近EW向及NW向构造复合部位控制,是勘查找矿的直接标志。
This paper summarizes the geochemical characteristics of the antimony ore mineralization in the area under the mouth through the analysis of the regional geological background, the geological features of the antimony ore, and points out that the ore deposit exists in the calcareous sandstone and sandy slate in the third lithologic section of the Middle Triassic. In siltstone, the orebodies are obviously controlled by the strata, tectonics and hydrothermal alteration, and have typical low-temperature hydrothermal mineralization features in West Qinling. The anomalies of antimony are controlled by the composite structures near EW and NW, Direct sign.
