| 摘 要： | 详细研究了辽宁丹东五龙矿区石英脉型金矿床中黄铁矿的产状、形态、成分、硫同位素及热电效应等特征, 提取了五龙金矿黄铁矿中重要的成因和找矿信息。首次利用黄铁矿微量元素的三角形图解对矿区深部远景及其外围靶区内矿脉的矿化远景进行了预测, 不仅为五龙金矿的成因研究提供了可信的矿物学依据, 而且对五龙矿区深部及其外围靶区内矿脉的矿化远景进行了有效的评价, 认为五龙金矿系中—浅成岩浆热液成因的金矿床, 矿区深部及其外围的220号脉、38号脉、2号脉的金矿化远景较佳。 |

| Abstract: | Wulong quartz vein type gold deposit is located in Dandong City, Liaoning Province, China It is a magmatic hydrothermal deposit enclosed in mylonite or ultramylonite The deposit is controlled by Jixingou Fault (F 2 ) and No 100 Fault (F 3 ) In this paper the authors studied minutely the occurrences, shapes, compositions and their typomorphic ratios (Fe/(S+As),Co/Ni,S/Se), sulfur isotopes, thermoelectric coefficients of the pyrites in Wulong quartz vein type gold deposit, analyzed the pyrite typomorphic coefficient characteristics, sumed up the pyrite genesis and prospecting typmorphic characteristics, took out the major genesis and prospecting information of the pyrite, prognosticated firstly mineralization perspective of the depth in the ore area and the quartz vein in outer target area by using the triangle illustration of the pyrite composition characteristic,which not only provided reliable mineralogy basis for the genesis of Wulong gold deposit, but also given efficient evaluation for prospecting assessment of the depth in the ore area and the quartz vein in outer target area The authors consider that Wulong gold deposit is mesogene and hypergene magmatic hydrothemal deposit It is very good for prospecting assessment of the depth in Wulong ore area and No 220 vein, No 38 vein, No 2 vein in outer target area |
| Keywords: | typomorphic characteristic pyrite quartz vein type gold deposit Wulong ore area Liaoning |
