The Yangbajing Geothermal Field is one of non-volcanic high-temperature geothermal fields. The Yangbajing convective system consists of two reservoirs at different depth. The shallow reservoir is constitued of loose alluvium of Quanternary and altered granite of Himalaya. Temperature inside the shallow reservoir is in the range of 150〜165℃ at the depth of 180〜280 m. Shallow thermal water is of sodium chlorite type and mixture of deep hot water and cold groundwater. The deep reservoir is in a slip-fault zone of the core complex. It is a veinor zone-shape reservoir. The deep reservoir can be divided into two parts. The upper parts of temperature 251℃ is at depths ranging from 950m to 1350 m. The lower part is below 1850 m , in which the measured temperature is as high as 329℃ . The deep thermal water is of sodium chlorite type, too. Carbon dioxide-is a major non-condensate gas in the shallow and deep reservoir.

The theory on small intrusions forming large deposits put forward by academician Zhongli Tang was a recapitulative summary by Long-term studying of magmatic Ni-Cu sulfide deposits which related to mafic-ultramafic intrusions. And this theory got a common response by exploration industry in the world. Many mineral exploration practices have effectively illustrated that the hypabyssal and small intrusion could always form the larger ore deposits. Our study is about the mineralization of Ni-Cu sulfide deposits which related to mafic-ultramafic intrusions in the northwestern of China. In this paper,we have discussed the theory of small intrusions forming large deposits,considering that mantle magma deep part liquation and injection is the main mechanism of this theory. And another theory of magma conduit systems,may cause the local enrichment of mineral,and like that theory of small intrusions forming large deposits. After summarizes the prospecting fact of magmatic Ni-Cu sulfide deposits in the northwestern of China,we expand the scientific connotation of the theory on small intrusions forming large deposits,and make it more realistic meaningful in guiding prospecting.
