The history of palaeogeography is over 200 years,and its origin and development are closely related with the development of stratigraphy and sedimentology.

它的发生、发展与沉积学和地层学的发展密切相关。

The studies of sedimentology and sequence stratigraphy are important indispensable aspects.

其中沉积学和层序地层学的研究是其中不可或缺的重要方面。

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。

The rock formation and isochronic sequence stratigraphic correlation framework have been set up which shows the sedimentary sequence in both Luxi and Jiyang depression is similar to each other, being of the same sequence architecture of'duality structure'but a bit differences in sedimentary system.

以多重地层划分及层序地层学理论为指导，运用沉积学、古生物学、地球化学、地球物理学方法和资料对研究区石炭二叠纪陆表海聚煤盆地的沉积层序进行了综合识别分析。

The Taihu Lake is situated in the centre of the dish-like lowlying land south of the Changjiang River, which was resulted from the two dynamic factors, the long-term ground depression at a rate of 0.4 mm/a, calculated from the archaeological data, and the rise of the postglacial sea level that was responsible for the formation of the high coastal plain on the east margin of the dish-like low-lying land.

本文从沉积学、地层学、地貌学、考古学和历史地理学角度，综合分析了太湖的成因和演变。认为地壳沉降与海面上升是构成江南碟形洼地的内外动力，为太湖的形成奠定了基础。全新世海侵最盛时，太湖海湾水深潮急、泻湖、滨海沼泽围绕海湾分布。随南部湾口沙嘴封堵，海湾趋于消失，陆地扩大，遗址增多。3700a来，海面回升，湖面逐渐扩展，形成现代太湖。

The sealing degree was firstly evaluated based on the sealing characteristics of the faults transversally and longitudinally, by means of comprehensive assessment of fuzzy mathematics.
