中文摘要:
      陕西省勉阳何家垭研究区位于秦岭山脉中段,处于勉略构造带、青川-阳平关断裂带、岷山-虎牙断裂带三者之间,区内地质作用复杂构造发育,区域成矿潜力巨大,为此在该区已知矿化点上进行了土壤热释汞可行性实验研究工作。采用了常规土壤吸附相态汞方法对土壤中的汞元素进行分析,利用由已知推测未知的实验原则确定出最佳实验温度为280℃,并根据最佳实验温度下所得实验结果结合地质背景条件,在研究区内圈定出有利的找矿靶区2个。其中1#靶区内发现有已知矿化点,并发育北东向断裂,并且发现黄铜矿化、镍黄铁矿化、磁铁矿化。2#靶区位于研究区西北侧,发现有钛铁矿、磁铁矿矿化带,矿化带走向为北东向,为下一步找矿工作提供方向。
英文摘要:
      The Hejiaya research area in Mianyang, Shaanxi Province is located in the middle section of the Qinling Mountains, between the Mianlue structural belt, the Qingchuan-Yangpingguan fault zone, and the Minshan-Huya fault zone. There are complex geological processes in the area and the regional mineralization potential Huge, for this reason, the feasibility study of soil thermal mercury release was carried out on the known mineralization points in this area. The conventional soil adsorption phase mercury method was used to analyze the mercury element in the soil, and the best experimental temperature was determined to be 280° based on the experimental principle of known speculation and unknown, and the experimental results obtained at the best experimental temperature combined with the geological background Conditions, delineate 2 favorable prospecting target areas in the study area. Among them, known mineralization points are found in the 1# target area, and north-east-trending faults are developed, and chalcopyrite mineralization, pyrite mineralization, and magnetite mineralization are found. The 2# target area is located on the northwest side of the study area. A titanium magnetite mineralization zone is found. The mineralization zone is north-eastward with ilmenite and magnetite, followed by limonite and other mineralization discoveries. Provide direction for future prospecting work.
