【Abstract】 The expert system is a new branch of artificial intelligence which came into existence only in the last decade.The system can arrange and integrate individual or collective knowledge and experience of the experts, and then simulate by computer the inference process which is traditionally performed by geologists brains. In contrast with inference purely by human brain,the expert system is more logical,rigorous,efficient and effective.To distinguish ore-bearing granites from hundreds of barren granitoids in Nanling area is a rather difficult task.This paper describes an expert system which is based on plenty of geological,geophysical and geochemical data as well as experience of many geologists.The system is designed to discriminate tungsten and tin mineralizations in granitoids of Nanling area.The system consists of three major parts:a knowiedge base which includes 34 inference rules,18 stationary knowledge tables,2 procedure modules and a relationship tree of parameters,an inference machine which can perform positive, inverse and inaccurate inference,and an interpretation module. This system has been used to distinguish granitoids with tungsten and tin mineralizations from the barren ones and the results are quite consistent with the data available.更多还原
