Abstract
Liba gold deposit is found by examination of lower anomalies.On the basis of introduction of geo-logical setting,ore-controlling factors and other features of deposit,the type of deposite genesis has been studied by comparison with the other gold deposits in went Qinling.The features of ore formation support that the fracture structures and Middle Triassic Series formation bed are key factors,and it has the same feature of geological set-ting and fracture as Lu’erba gold deposit,but obviously different in composition of ore.It is a epithermal gold deposit.
