On the base of large quantitative test, using coal petrography and organic geochemical data, the source of oil and gas in the coal-measures is analyzed. And it is concluded that the area's Yan'an group coal-bed has a low potential of oil production, and the oil and gas contained in the coal-measures and superjacent strata comes from underlying Upper Triassic Yanchang group strata. After a series of parameters of coal seam and surrounding rocks are tested, gas formation, storage, preservation, permeability of the coal-rock seam are analyzed and evaluated.

Based on the above research, we analyzed regional metallogenic conditions from geology, geophysics and geochemistry. Considering regional strata, some source beds with ore-bearing strata controlled apparently metallogenesis. The strata contained hydrothermal siliceous rock or siliceous albitite ether formed some favorable source beds and established substantial foundation for later diplogenetic metallogenesis e.g.

从区域地层上来看，含特殊层位的矿源层对成矿有明显的控制作用，其中含热水沉积成因的硅质岩或硅质钠长质岩的地层或形成有利的矿源岩，为后期叠生成矿奠定物质基础，或直接形成工业矿床；另外，区内黑色页岩（包括碳质板岩、碳质泥岩、碳质页岩和含碳钙质板岩等）也是很好的矿源层。

According to the research of the paper, the "migmatite" of the Sizishan Formation, Xingdong Group distributed in northern Xiao Hinggan Mountains should be a suit of gneissic quartz monzonitegranite intrusions. Their whole rockmineral Rb-Sr isochronic dating is (482±19) Ma, indicating that an Caledonian magmatic events existed in the giant granitic belt of the Xiao Hinggan Mountains.
