| 摘 要： | 通过对洞子沟银矿床黄铁矿成分、热电性标型、石英微量元素和热发光特征测试,发现2、3号矿体石英微量化学Co/Ni平均值为0.33,具层控矿化的特点;据矿床地球化学特征推断洞子沟银矿床成因与海相火山无关,认为洞子沟银矿床具备典型沉积改造型层控矿床基本特征.黄铁矿热电性标型为低值N型,石英热发光曲线出现双峰,峰形较正常等显示洞子沟银矿本区深部具较好找矿远景.

| Abstract: | By testing the composition and the thermoelectric mark of pyrite, the trace element composition and thermoluminescene character of quartz, the average Co/Ni value in quartz in No.2, and 3 orebodies of Dongzigou deposit is 0.33. It shows that this deposit has layer-controlled characteristic. According to geochemistry of ores and rocks in the Dongzigou area, it is inferred that the formation of Dongzigou silver deposit has no relations with marine volcanism, and has the basic characters of typical sedimentary-reforming layer-controlled deposit. The pyrite thermoelectric mark is a low level N-type. The quartz thermoluminescene curve has two normal apexes. All evidences manifest that the deep section in the Dongzigou silver deposit has rather better prospecting. |
