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

Analyzing the model, especially the activity of Taihang Mountain piedmont fault, we got such main conclusion:1. Based on sequence stratigraphy, the strata is divided from the selected drills. And the Quaternary stratigraphic framework of Handan city is established, dividing the Quaternary strata into four parts- Qh, Qp3O , Qp2Y and Qp1G.2. With all the selected drill data of Handan city, a drill database is established. A quaternary strata 3D model of Handan city is imitated by GOCAD and ArcGIS, and so are the bottom structural map of each horizon.3. Analyzing the 3D model and the contradistinction section of drills, we got: the stratum of Qh and Qp3 is smooth and flat, with a feature of a higher west, little difference between south and north and undistinctness of faults; there are several depocenters along S-N and N-W in the stratum of Qp2, and the evolution of the stratum is controlled by a couple of ruptures, which means the tectonic movement is active in this period of time.4. Since quaternary, main tectonic movements happened in Qp2 and have been stable in Qp3 and Qh.
