Abstract:

Longtougou gold deposit which is a tectonic-altered rock type occurred in the east section of south Qinling orogenic belt，was found in recent years from the Devonian sandstone.It is mesothermal magmatic deposit controlled by tectonic.In the light of the geological characteristics of the deposit and main ore-controlling conditions，we hypothesized that the main orebodies are controlled by nearly east-west fracture，with its tendency in contrast to that of Devonian sandstone.The deposit morphology and quality are variably controlled by the lithology of surrounding rock，alteration intensity and occurrence elevations.Combined with peripheral progress in recent years，we suggested that future work of ore exploration should be performed around the shear fracture structure，mineralized alteration zone in the area and the periphery of geochemical anomalies，as well as the anticline ore prospecting work in the south.

Key words: ore-controlling conditions, mineralization regularity, tectonic-altered rock type gold deposit, Longtougou gold deposit, South Qinling orogenic belt
