This paper presents new data of electronic microprobe analvses on clinopyroxenes from the layers of picrite and associated basalt in this area. It is shown that the clinopyroxenes from the picrite are exclusively diopside, whereas those from the basalt are diopside and augite, suggesting a continuous variation in composition.

本文对该地区苦橄岩及其共生的玄武岩中单斜辉石的矿物化学成分进行了电子探针分析，结果表明，苦橄岩中的单斜辉石全部为透辉石，玄武岩中的单斜辉石种属有普通辉石和透辉石两类，但玄武岩中的单斜辉石成分呈连续演化关系。

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
