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
