Abstract:

Yangshan gold deposit,located in W en country of Gansu province,is a supper large fine—grainted disseminated gold deposit,belongs to the South Subzone of the West Qinling in geotectonics.The ore body occurs in Middle Devonian Sanhekou group epimetamorphic stratum.By analyzing the characteristics of gold content in regional stratUB ,REE,S,H ,0 ,C isotopes,it shows that the ore—forming material source of Yangshan gold deposit are main magmatic fluid,Secondly for devonian stratum and Bikou group stratum.

Key words: Ore—forming material, Fined—graited disseminated type, Yangshan gold deposit, Gansu
