A good many mico-landblock of the early Neoproterozoic-Cambrian volcanic rock that distribute in the Tianshan orogenic belt and on its both sides, and the Carboniferous-Permian volcanic rocks that widely distribute in the Tianshan and adjacent regions are selected for subject investigating in this paper. Renewing the ocean-land format and ocean-land conversion process of Tianshan orogenic belt in the Paleozoic is the masterstroke for this paper. On the basis of detailed field investigation, many subjects, such asregional lithology、geochemistry、structural geology、volcanic sedimentology geology、sotope geochronology and synthesis analysis study of geophysics data, are adopted as instrumentality in the paper, this study lays emphasis on the formation, evolution and dynamics of early Neoproterozoic-Cambrian and Carboniferous-Permian volcanic rock in the Tianshan and its adjacent regions to find out Carboniferous-Permian volcanic rock property, eruptive sequence, time and space distribution characteristics, to resume and reconstruct evolution process of Carboniferous-Permian volcanic rock, and to explore connection of magmatism process and lithosphere stretching action of neopaleozoic ocean-land transformation in the Tianshan region.

本文选择分布于天山及其两侧的诸多微陆块上新元古代—早寒武世火山岩和天山地区广泛发育的石炭纪—早二叠世火山岩为研究对象，以恢复重建天山造山带古生代洋陆格局和洋陆转换过程为主线，在详细的野外工作基础上，综合运用区域岩石学、地球化学、构造地质学、火山沉积学、同位素地质年代学、区域地球物理资料综合分析研究等多学科手段，重点研究天山及其邻区新元代—早寒武世和石炭—二迭纪火山岩系的形成演化及其动力学，查明天山石炭纪火山岩系的性质、喷发序列、时空分布特点，恢复重建其形成演化过程，探索天山地区晚古生代洋陆转换过程中火山岩浆作用与岩石圈拉伸作用的关系。

But the research on Neopaleozoic petroleum reservoir geology and pool-forming conditions in this area is a weak point all the times, as restricts Neopaleozoic exploration activity in south of North China. Therefore, the research on Neopaleozoic petroleum reservoir geology and pool-forming conditions in south of North China Basin is very important for objectively evaluating exploration prospect and optimizing exploration targets in Neopaleozoic of south of North China.
