The main characteristics of the skarn are as follows:(1)occurring as bedded,para-bedded in the contact zone between carbonate and microclastic rock,and its occurrence being accordance to the strata;(2)cut by later vein rock,so having no relation with the magmatic rock on genesis;(3)metasomatic skarn having replacement remnant texture,pseudobreccia structure,while depositional skarn,particulate crystall...

Large condensate gas pools are developed in the Ordovician and Carboniferous in the Lunnan low salient. Geochemical study shows that the Ro of gas condensate in these gas pools is in the range of 0.8% 1.0%(far below the threshold of R o＝1.3％ for thermal cracking), and the condensate gas is overmature dry gas (with R o＞2.0%). Moreover, the crude oil and dry gas in the study area were charged in different stages, indicating that the genesis of the condensate gas was not thermal cracking.

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

Combining the available regional geological and geophysical research, the petrogenesis of the magmatism was studied. As a response and absorption to the IndiaAsia collision, the northeastward flow of the asthenosphere beneath the Tibetan Plateau along the 400 km depth interface was blocked by the North China craton, and caused a systemic sequences in West Qinling Region, including the strikeslip fault systems and pullapart basins in the shallow crust and the origin of the twotype magmatism in this work in deep lithosphere. This explanation is consistent with the lithology and plumelike geochemical features of the kamafugite and potassic trachybasalt, which are significantly different from the potassic magmatism within the plateau and its adjacent regions.
