In order to solve the important and basic problem of the petrogenesis of "Tiantangzhai migmatitic granite" in the core of Dabie orogenic belt, the detailed 1∶50000 regional geological surveying and the big scale dissection of important region (metamorphic rocks, granites and structure), were operated in about 900km〓 area near Tiantangzhai peak. On the bases of the petrology, mineral chemistry, geochemistry of rare earth element and microelement, isotope geochemistry and chronology, physicochemistry, magmatic dynamics, geodynamics, diagenetic simulation, and regional geophysical data, the theory of cooling age and historical geochemistry and the viewpoint of tectonic evolution are applied to study the petrogenesis of Yanshan epoch granites of this region. On the bases of above studies, the process of tectonomagmatic dynamics after indo-Chinese epoch in Dabie orogenic belt is discussed. The important conclusions are gotten

During the 1∶200 000 regional geological survey of the Songleng and Zhuwagen Sheets, Tibet, the author studied the geological mineral deposit, petrological, mineralogical, geochemical characteristics of serpentinic jade in the Guiyala area, Zogang county, which indicates that serpentinic jade was formed by the action of magmatic hydrothermal solutions on the Xiongen Co Formation dolomite.

在西藏1∶20万松冷幅、竹瓦根幅区域地质调查中，对左贡县桂亚拉地区发现的岫玉矿的地质特征、矿床特征、岩石、矿物和地球化学特征研究表明，雄恩错组的白云岩受岩浆热液作用形成的岫玉，为研究西藏非金属矿床成矿规律和构造演化及寻找玉石提供了新的基础资料。

Based on the field deposit-geological investigations, structural analysis and petrochemistry studies, this paper presents a Miocene intraplate thermo-upwelling extensional metallogenic model of the Zhunuo porphyry copper deposit which is tectonically controlled by the nearly east-west and north-south extensive faults related to lower crustal flow. The ore-bearing porphyries have the characteristics of typical adakitic rock.
