On the basis of a study and elaboration of data, some important conclusions are presented:(1) ruby deposits in marbles occur in the plutonic metamorphic zones of orogens where deep fault structure is developed;(2) ruby-bearing rocks are calcic crystalline marbles, rather than magnesian marbles;(3) amphiboles in ruby-bearing rocks are not tremolites, but silica-poor, alumina-rich and chrome-bearing calcic amphiboles, such as chrome-bearing magnesio-sadanagaites; and (4) the deposits are genetically of thermodynamical metamorphism type, rather than of pneumatolito-hydrothermal type or skarn type.

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

In combination with seismic reflection features and probable gas resource discussion, it is concluded that there probably exist two kinds of reservoir models in the X Block. In the areas where faults or collapse structures develop, the gas resource is probably composed of thermogenic gas, gas hydrate is characterized by multilayer distribution, while in the inactive areas the gas resource is probably composed of biogenic gas, and gas hydrate is characterized by monolayer, which mainly distributes in a narrow zone on the surface of BSR (bottom-simulating seismic reflector).

The outgas types and amount of different gas resource varied with the different geological conditions and evolution processes. There are four outgas models including the model in which inorganic gas directly overflows from mantle matter through lithospheric fracture,the model of heat flow piercement outgas,the model of volcano-magma outgas,and the model of carbonate rock outgas due to heat metamorphism.
