Abstract:

Jinlongshan gold ore belt,which is located in Southern Qinling,can be divided into four equi-distance mineralization segement of Jinlongshan,Yaojian,Qiuling and Guloushan from east to west.The orebodies of the gold belt are hosted in the Upper Devonian Nanyangshan Formation and the Lower Carboniferous Yuanjiagou Formation.Compared to the calcium muddy siltstone,silty shale,calcareous shale and other favorable lithology,the formations are just ore cluster place,but the lithology play an important role in ore-controlling.Furthermore, the structure is well developed in this area.The regional faults control the distribution of the entire ore belt,and the secondary faults strike in NE and EW control the distribution of the ore segment and the position of gold ore vein. Thus,the faults and favorable lithology together control the mineralization of Jinlongshan gold ore belt.

Key words: fault, lithological combination, micro-disseminated gold deposit, gold mineralization enrichment zone, Southern Qinling Mountains
