摘要:

金龙山金矿床处于南秦岭印支褶皱带,区内上泥盆统南羊山组是金矿化体的赋矿地层,下石炭统袁家沟组是重要的锑矿化体赋矿层位。控矿构造主要由EW向剪切褶皱带、NE向左行走滑断裂和NW向右行走滑断裂组成,主断裂与次级断裂均起控矿作用。构造地球化学研究显示,Au元素沿NE向呈串珠状分布,线状平行排列的特点也非常明显,与NWW向断裂带交会形成了元素富集区。构造地球物理(EH4)测量显示,金龙山矿段EW向构造为复式褶皱带,叠加后期NE、NW向断裂带。金龙山金矿NE向矿脉以106号脉体群为代表,106号脉体群呈带状展布,由几条近平行的脉体组合而成。通过总结该区赋矿规律,为下一步找矿提供了新的理论依据。

Abstract:

Jinlongshan gold deposit located at indosinian fold belt of the south Qinling Mountains,the Nanyangshan Group on the devonian series belonged to gold mineralization body of ore formation,and the carboniferous Yuanjiagou Group was an important assignment of antimony mineralization body seam.Ore-controlling structure was primary composed with northwest to the shear fold belt,northeast left strike-slip faults and northwest strike-slip fault to the right.Moreover,tectonic geochemical study showed that the Au element arranged as a string of beads along the north-east distribution,the characteristics of linear parallel arrangement was extremely obvious as well,which can form the enrichment region combined with the north-west fault zone.Additionally,tectonic geophysical (EH4) measurement displayed that the Jinlongshan ore block was overall east west to the structure of double fold belt,late superposition of north east and north west faults.The Jinlongshan gold deposit can be represented by 106 pulse volume group,and the group presented the zonal distribution and was composed with several nearly parallel vein bodies.By summarizing the law of ore,we provide a new theory basis for the next step prospecting in the future.

Key words: micro-disseminated type gold deposit, law of ore, tectonic geochemistry, tectonic geophysical, Jinlongshan gold deposit
