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

From about 206 Ma there occurred arc-continent collision accompanied by compressional contraction and shearing deformation of the arc crust and development of syn-collision granites. In the late Yanshanian epoch (138-73 Ma) post-orogenic extension came into action and resulted in the generation of A-type granites. During the Himalayan (65-15 Ma) intra-continental orogenic movement a large-scale strike-slip thrusting induced the intrusion of granites and development of pull-apart basins.

By studying the deformation and evolutionary sequences around the Panshan granitic pluton, east-central Yanshan orogenic belt, and 40 Ar/ 39 Ar thermochronological test and analysis,we present the structural evolutionary process of the overlying strata before pluton intruded as well as it was intruding. The sequences of regional deformation are as follows: before the intrusion of Panshan granitic pluton, the N-S trend contraction in the east-central Yanshan orogenic belt took place, which resulted in the regional EW-trending Malanyu multi-fold and Jixian thrust fault; then Panshan granitic pluton intruded into the south limb of the Malanyu multi-fold and cut-through the Jixian thrust fault; later, the reactivity of the Jixian thrust fault cut off the synclines around thePans han granitic pluton.
