Qinglonggou gold deposit is located in the northern margin of Qaidam Basin and sourthern Qilian o- rogenic belt�� The deposit is controlled by northwest trending layer slip fault of Qinglonggou anticline fold and be- longs to altered rock type of ore�� According to mineral combination and interspersed relationship��the mineraliza- tion process could be divided into three stages: non- ore quartz veins stage (stage ��)��quartz -pyrite sulphides stage (stage ��) and quartz carbonate stage (stage��)�� Petrographic and microthermometric study of fluid inclu- sions indicate that the fluid inclusions of different stages in quartz are mainly gas- liquid two- phase inclusions��and appear pure liquid in the quartz carbonate stage�� The homogenization temperatures are successively concentrated in 200�� ��240�棬 170�� ��210�� and 130�� ��160�棬correspondingly ore- forming pressure are 24. 39 MPa��17. 30 MPa and 11. 84 MPa while ore- forming depth are 2. 4 km�� 1. 7 km and 1. 2 km during the mineralization stages �� �򣬢� On the basis of fluid features and the geological characteristics��the Qinglonggou gold deposit is defined as an epizonal orogenic in genetic type��
