第四纪地质定年与地质年表

时、空、质(物质)、能(动力)是研究地质过程、环境演变的基本要素，其中时间是关键．任何一个自然事件、任何一个地质过程，都与时间相关联，时间的重要性需要通过年龄的精确测量来体现。本文综述了第四纪定年的基本方法和特点以及近年来年代地层学所获得的进展，提出了中国第四纪的划分简表。     

临沧超大型锗矿床有机质与锗矿化的地球化学特征

临沧锗矿床是一产于第三系含煤岩系中的超大型矿床。矿床的最初锗源与盆地西缘的二云母花岗岩有关。主矿体产于下煤组沉积旋回的早期地层中，每一沉积阶段早期形成的褐煤和碳质泥岩中富含锗，最高含量达１４７０×１０＾－６。褐煤和碳质泥岩在矿化过程中平均富集了１６４－１６９倍。根据锗含量，褐煤和碳质泥岩可分为锗含量小于１２×１０＾－６的低锗煤（泥岩）和大于９０×１０＾－６的高锗煤（泥岩）。高锗煤中有机质富含氧官能     

Study of the liquefaction resistance of a saturated sand reinforced with Geosynthetics

This article presents various tests using a cyclic triaxial instrument, on samples of saturated Hostun RF sand, reinforced with circular sheets of geosynthetic material. Tests performed with different types of geosynthetics of different compressibility, rigidity and roughness characteristics indicate a significant increase in liquefaction resistance for samples reinforced with compressible, non-woven geotextiles. The undrained behaviour of saturated Hostun RF sand reinforced with non-woven geotextiles is analysed on the basis of different test series. This analysis highlights the influence of reinforcement compressibility on interstitial pressure distribution in the sample, thus showing the role of this type of inclusion in the increase in liquefaction resistance.     

Soil-structure interaction analysis of the Hualien containment model

This paper presents results from forced vibration tests, microtremor observations and earthquake response analysis of a nuclear reactor containment model constructed on stiff soil in Hualien, Taiwan. The dynamic behavior of the soil-structure system is simulated successfully with two numerical models: a sway-rocking model, whose soil parameters are evaluated on the basis of the continuum formulation method, and a finite element model, using the program SASSI with the flexible volume substructuring approach. The dependences of the soil parameters of both models on the amplitudes of the different dynamic excitations are investigated in detail. An original numerical simulation of microtremor is performed. Comparison with results of a previous study involving a rigid tower on a soft soil site in Chiba, Japan is offered.

华北地区煤的显微组分结焦性热台试验

为探讨煤的显微组分的结焦性，对不同变质程度煤的镜质组、壳质组和惰性组分别进行了显微镜热台加热试验．在加热过程中，活性组分经历了３个明显不同的变化阶段，即变形阶段、胶质体形成阶段以及固化阶段．随煤变质程度的增加，镜质组的初变温度和胶质体形成时的温度逐渐增大，而固结温度变化规律不明显；壳质组在低变质阶段因受热而挥发掉，但随煤级增高其变形程度减弱；半镜质组在受热过程中也有变形和少量胶质体形成，而惰性组只发生微弱变化．在低变质阶段，活性显微组分形成的焦炭显微结构以各向同性为主；随变质程度的增高，焦炭显微结构中各向异性成分比例增大     

Quantitative Tectonic Markers of Large Coastal Earthquakes in Fujian, Guangdong, Taiwan and Hainan——with a Discussion of Qualitative Indicators

This paper expounds the quantitative tectonic indicators and some qualitative indicators of large earthquakes in the coast areas of Fujian, Guangdong, Taiwan and Hainan. The main quantitative indicators include uplift amplitude of the Moho, Quaternary and Late Holocene coasts. The paper also gives a brief account of the research method on quantitative indicators of surface uplifted zones. Taiwan is a famous neotectonic zone and an area of large earthquakes in the world. There is only one large-earthquake area in each of Fujian, Guangdong and Hainan Provinces. Along the coast large earthquake areas there are certainly many remains of crustal activity. Among these remains, coast activity, taking the sea level as the accurate marker horizon, can determine not only the amplitude of coastal elevation and subsidence in a certain period, but also the cycle and rate of positive or negative movements.

岩浆活动旋回与地球多层对流系统

从地球历史的节律角度讨论岩浆活动旋回。岩浆活动旋回可按时间与空间分出相互对应的不同尺度，进而可与深度尺度不同的地球多层对流系统相互对应，从而给予了岩浆活动旋回的动力学意义。岩浆活动的时间周期愈长，空间尺度亦愈大，需要的维持岩浆源存在的热能、挥发分供给的数量与深度亦愈大。
