On the basis of detailed studies on the geological setting,ore-forming pro-cess and ore-bearing fissure systems of the Jinduicheng porphyry molybdenumdeposit,Shaanxi Province,the geological conceptual model and distribution pat-tern of permeability have been established for the Jinduicheng deposits,Accor- ding to the law of conservation of mass, momentum and energy,a set of gover-ning differential equations representing transport phenomena of heat and fluid during the ore-forming process have been proposed,The distribution patternsof stream function and temperature are obtained through the numerical solutionto these equations by using the finite element method,and Darcy velocity andheat flux can be further calculated. The results of the study show:(1)The hydrothermal system has a temperature gradient as high as 100℃to 120℃per kilometer,The heat anomaly may last over n ×10 ̄5 years,which is comparable with the active geothermal system in the modern volcanic areas. (2)As porphyry stocks connect with a batholith at depth, the tempperature field is controlled mainly by the batholith. (3)The distribution patterns of stream function and Darcy velocity are dependent on the permeability of wall rocks, and the orebodies are located in the rea which has the largest velocity and the highest density of stream function. (4 )The distribution patterns of Darcy velocity and stream function are related to the shape and mode of occurrence of the intrusive body,In the vicinity of the orebodies,the Darcy velocity changed obviously during the ore- forming process,This mainly resulted from the variation in permeabilities of rocks. In comparison with the previous similar work,this study has the following features:(1)The geological model and the distribution pattern are established onthe basis of the studies on large quantities of geological data. (2)The selection of parameters and the calculation results have been eXamined by the observation data of modern active geothermal systems. (3)For the simulation of heat and fluid transport,the variation in perme- ability in space and time and the disparity in physical features of rocks have been considered. (4)The Ritz and Galerkin methods have been applied in the finite ele- ment analysis. The computational programs are easily understandable and are also ready to be modified and enlarged.In addition,the structure of the programs is very clear,All the computer results are output in the way of contour diagrams,including streamline map,isomermal map and Darcy velocity distribution map.
