In this paper, the petrology, mineralogy and geochemistry of basic-ultrabasic volcanic rock, granite and skarn related to the Sn-Cu skarn-type ore and the vein-type ore in Laochang ore field have been researched systematically, some conclusions are summarized as follows:In Gejiu tin-polymetallic district, the middle Triassic volcanic rocks belonging to calc-alkaline basalt-tholeiite serie, mainly consist of pyroxene, hornblende, feldspar, chlorite and phlogopite; All the granites are peraluminous granites related to the Yanshanian collision-orogeny. Laoka granite closely related to the tin-polymetallic deposits emplaced in the post- orogenic.The metal elements show obviously vertical zones with the variety of skarn types in dimensional extension; The occurrence of garnet skarn and diopside skarn alternately developed in the horizontal zones of the contact between granite and carbonatite are mainly related to two factors: one factor is the infiltration metasomatism of post-magmatic hydrothermal solution, the another is the metrical strata of marble and calcic-dolomite developed in country rocks.

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
