The principal contents of the symposia on stratigraphy in the 31st International Geological Congress comprise the following aspects:geologic time scale, biostratigraphy, event stratigraphy, sequence stratigraphy, magnetostratigraphy, isotopic stratigraphy, integrated stratigraphy, sedimentary facies and palaeogeography, palaeobiogeography, and tectono-palaeogeography.

介绍了第 3 1届国际地质大会有关地层学学术讨论的主要内容，包括地质年代表、生物地层学、事件地层学、层序地层学、磁性地层学、同位素地层学、综合地层学、沉积相与沉积古地理、生物古地理、构造古地理 10个方面。

Palaeogeography is a branch of geosciences, which studies natural geographical features in the geological history. The research targets are the evolution history of oceans and continents, and the distribution and characteristics of the internal palaeogeographic units.

古地理学是研究地质历史时期自然地理特征的地质科学，其研究目标是海洋和陆地的变迁历史及其内部古地理单元的分布和特征。

Most of Xinjiang is young geologically, having been formed from the collision of the Indian plate with the Eurasian plate, forming the Tian Shan, Kunlun Shan, and Pamir mountain ranges.

相对年老的地质层组主要分布在遥远的北部和东部，北部的准噶尔盆地的某个区域从地质学上说隶属哈萨克斯坦，而东部的地质层组则属于华北克拉通。

With the development of underground structures in Shanghai, the ground freezing method is more and more widely used in tunnel construction (such as the soil reinforcement of the passway and pumping house of tunnels).

冻结法施工在上海隧道建设中（如隧道旁通道、地下泵房等的设计与施工）得到广泛应用，也曾引发过严重的地质灾害（如上海地铁4号线外滩段的地质灾害）。

Mr.Zhang Renjian was a famons patriotist geologist,who was a pioneer in the development of mining industry of north western part of China in the 1920s and a pathbreaker,organizer and leader from the 1930s to the 1940s in the geological work in Henan Province;he was also a meritorious worker in the establishment of Xuanhua School of Geology in the 1950s.

张人鉴先生是爱国的有贡献的老一辈地质学家。他是 2 0世纪 2 0年代开发大西北矿业的先驱；30年代至 40年代河南地质工作的开拓者、组织者及领导人；50年代创建宣化地质学校的功臣

There are a lot of complex and well-regulated petroliferous geologic bodies distributed widely during the sedimentary and structural evolution of plates.

块体的沉积构造演化控制了数量众多、分布广泛、复杂而有序的含油气地质体的形成，而油气地质体又决定了油气的有序分布。

So, the integrative exploration should be made according to the development and distribution laws of the petroliferous geologic body.

根据油气地质特征、构造背景等差异，将中国大陆划分为23个主要的油气地质块体。

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

本文针对大别造山带核部&天堂寨混合花岗岩&成因这一重大基础地质问题，在天堂寨一带近900km〓的面积上进行了详细的1∶5万区域地质调查和大比例尺重点区解剖，通过对区内燕山期花岗岩进行岩石学、矿物化学、稀土微量元素地球化学、同位素地球化学和年代学、物理化学、岩浆动力学、地球动力学和成岩计算机模拟等研究的基础上，结合区域地球物理学资料，应用冷却年龄、历史地球化学理论和构造演化观，阐明区内燕山期花岗岩成因，并以此为基础进一步讨论了大别造山带自印支期以来的构造—岩浆动力学过程，取得了如下的重要认识

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.
