In Zhangbaling Tectonic Belt, two types of mineralizaton, arifous quartz veins and alter-ation halos, can observed within many deposits. The pressure of metallogenesis of auriferous al-teration halos is much bigher than that of quartz vein. The temperatures of metallogeneses of these two types of orebodies are don't the same Geochemistry study indicates that both of them are mi-cro-mesothermal deposits related to Yanshanisn granites The results of proton microprobe analy-sis of sulphides from the gold deposits in the area show that the "invisible"gold in sulphide min-crals within quartz veia is poorer than that from alteration halos. Field observation shows that the structural modality of the fractures controlling the orcbodies of auriferous quartz vein is different from that of the auriferous alterations zones.The fracture controlling the orebodies of auriferous alteration hatos is compress shear fracture. Auriferous quartz vein is controlled the orebodies of auriferous alteration hatos is compress shear fracture aurifcrous quartz vein is controlled by excensive fault. The alteration halos erosscut by auriferous quartz vein. The wallrocks of the former altered strongly and developed alteration xones well. The wallrocks of auriferous quartz vein altered slightly The results of tectonogeochemicsl study shows that the concentration of associated met-allogenesis elements and intensity of alteration are positively correlated with teetonle deformation strength for auriferous alteration halos.It indicates that it is probably a general character for mi-cro-mesothermal gold deosits due to the multisrages of metallogeneses took place.The tectonic environment is the most important fact dctmicing the meehanism of fluid flow and prcciitaion

The H.O. S isotopic geochemical features and the REE gochmical parmetes of some deposits in Xinong’erslan region are dis-cussed. And the cosernt various geological bodies are coafimed.

Based on the concept and theory of geologic body geometric modeling, the essential ways and techniques for building computer system of geometric modeling of geologic bodies were presented. The data structures of geologic body geometric modeling, construction of geologic bodies models, geometric operation and entirety properties analyses of geologic bodies were discussed. In addition, the concrete process for auto- mated ore-delineation and automated generation and plotting of exploration profile maps by using these theories and methods were put forward, and some actual application examples were also given.
