云南丽江地区断裂构造岩岩组动力学研究

丽江地区构造岩岩组动力学研究表明，研究区内中更新世末构造主压应力保持在北西至北西西方向变化；晚更新世中期之后构造主压应力方向则以北北东至北东方向为主变化，并有逐渐向近南北向转化的特点。因此玉龙雪山东麓断裂在中更新世末曾有过左旋压扭活动为主的历史，兼有左旋、右旋的活动过程，1996年2月3日丽江M7．0地震的破裂过程继承了晚更新世后期断裂的活动特点。     

Investigating Landslides Caused by Earthquakes – A Historical Review

Post-earthquake field investigations of landslide occurrence have provided a basis for understanding, evaluating, and mapping the hazard and risk associated withearthquake-induced landslides. This paper traces thehistorical development of knowledge derived from these investigations. Before 1783, historical accounts of the occurrence of landslides in earthquakes are typically so incomplete and vague that conclusions based on these accounts are of limited usefulness. For example, the number of landslides triggered by a given event is almost always greatly underestimated. The first formal, scientific post-earthquake investigation that included systematic documentation of the landslides was undertaken in the Calabria region of Italy after the 1783 earthquake swarm. From then until the mid-twentieth century, the best information on earthquake-induced landslides came from a succession ofpost-earthquake investigations largely carried out by formal commissions that undertook extensive ground-based field studies. Beginning in the mid-twentieth century, when the use of aerial photography became widespread, comprehensive inventories of landslide occurrence have been made for several earthquakes in the United States, Peru, Guatemala, Italy, El Salvador, Japan, and Taiwan. Techniques have also been developed for performing ``retrospective' analyses years or decades after an earthquake that attempt to reconstruct the distribution of landslides triggered by the event. The additional use of Geographic Information System (GIS) processing and digital mapping since about 1989 has greatly facilitated the level of analysis that can applied to mapped distributions of landslides. Beginning in 1984, syntheses of worldwide and national data on earthquake-induced landslides have defined their general characteristics and relations between their occurrence and various geologic and seismic parameters. However, the number of comprehensive post-earthquake studies of landslides is still relatively small, and one of the most pressing needs in this area of research is for the complete documentation of landslides triggered by many more earthquakes in a wider variety of environments.

Proglacial Sediment—Landform Associations of a Polythermal Glacier: Storglaciären, Northern Sweden

Mapping and laboratory analysis of the sediment—landform associations in the proglacial area of polythermal Storglaciären, Tarfala, northern Sweden, reveal six distinct lithofacies. Sandy gravel, silty gravel, massive sand and silty sand are interpreted as glaciofluvial in origin. A variable, pervasively deformed to massive clast‐rich sandy diamicton is interpreted as the product of an actively deforming subglacial till layer. Massive block gravels, comprising two distinctive moraine ridges, reflect supraglacial sedimentation and ice‐marginal and subglacial reworking of heterogeneous proglacial sediments during the Little Ice Age and an earlier more extensive advance. Visual estimation of the relative abundance of these lithofacies suggests that the sandy gravel lithofacies is of the most volumetric importance, followed by the diamicton and block gravels. Sedimentological analysis suggests that the role of a deforming basal till layer has been the dominant factor controlling glacier flow throughout the Little Ice Age, punctuated by shorter (warmer and wetter climatic) periods where high water pressures may have played a more important role. These results contribute to the database that facilitates discrimination of past glacier thermal regimes and dynamics in areas that are no longer glacierized, as well as older glaciations in the geological record.     

板块下的构造及地幔动力学

最新的全球地幔地震层析资料揭示了岩石圈板片可以俯冲到核幔边界，超地幔羽可以从核幔边界上升到地壳上部形成热点。在大陆板块汇聚边界，地幔地震层析图像不仅显示了岩石圈板片的超深俯冲，还保存了拆沉的岩石圈“化石”残片的重要信息。从地幔深部所获取的新资料为全地幔“单层对流“的新模式提供了依据。在介绍上述全球构造研究新动向的基础上，本文强调了研究岩石圈板块必须了解板块下的构造，探索岩石圈板块的驱动力应该从“岩石圈动力学”升华到“地幔动力学”，并提出了大陆板块汇聚边界地幔动力学研究的新思考。     

北京城地域沿革及发展思考

位于华北平原北部的北京,东西北三面环山,形如海湾,中间为一小平原,是地质历史演变成的一块风水宝地。自春秋战国时期作为燕都蓟城,经秦、汉、晋、隋、唐、五代、宋(辽、金)等历代变迁,于金贞元年建都,至其后的元、明、清,多作为都城,先后定名为中都、中都永安府、大都、大都路总管府、北平府、北京、京师顺天府。自辽代起北京城范围比今北京大。北京城地域演变是社会经济发展和人们生活需求自然形成的,它应对现今城市规划布局、人才建设具有重要的参考价值。     

层序成因动力学中的构造因素研究

本文以层序－盆地－构造为主线，对层序成因动力学中的构造控制进行了研究。结果表明，层序发育的构造控制主要表现为：1）构造控制盆地边界，进而控制层序充填轮廓；2）构造级次控制层序和层序级别；3)构造属性控制盆地性质，进而控制层序成因格架和界面成因类型；4)随着层序规模和界面级别的增大，构造控制的意义和痕迹越明显；5)同沉积断裂活动控制层序的内部构型；6)构造基底活动形式控制着层序容纳空间和结构型式；7)构造演化控制着盆地演化及性质，进而控制着层序充填样式和组合类型。
