2. tazhong ancient uplift originated from normal fault in paleozoic, hydrocarbon formed in ordovician period, structure reverse made tazhong uplift form from the middle ordovician period to the late ordovician period, and it provided geologic background for the deposit of silurian - devonian stratum. tazhong uplift formed at the end devonian, ancient reservoir was destroyed and asphaltum sandstone formed, structure deformation more destroyed ancient reservoir in early permian, after then the major of structure deformation is regulation
塔中隆起源於早古生代拉張背景下的正斷層,寒武-奧陶紀為其烴源
巖形成的重要時期;早奧陶世末-晚奧陶世末的構造反轉是塔中隆起的主要形成期,同時也為志留系形成地層及復合圈閉提供了古地理背景;志留?泥盆紀塔里木盆地南北緣均轉為活
動大陸邊緣,形成了大量的斷裂和不整合;泥盆紀末塔中鼻狀隆起基本定型,古油藏遭受破壞,形成了瀝青砂

Based on the analysis of thermal contact metamorphic aureoles, granitoid interior structure, quartz axis fabric and strain characters in the different rock unites of yuanshishan granitoid and its wall rocks, the emplacement mechanism of yanshishan granitoid was studied. the magmatic explictite dynamic was advanced in light of regional stress and magma dynamic research. those conclusion was synthesized to ascertain the emplacement mechanism - granitic magma ascended in dikes with the minimum critical width of the magma ascending channels about 2. 213. 88m and located in the core of yindianshan dome with the passive style of dyke explictite ; the later unite is a kind of multiple emplacement mechanism with the character of active emplacement of ballooning
