地质学的

Our project is based on Cenozoic volcanic rocks and deep seated xenoliths in it to reconstruct the source composition and ctructure. We did field investigation, collection of samples, determination of age and composition characteristics of selected samples. The new achievements are following. 1 recognized a potassic metasomatic source of the Cenozoic volcanic rocks through an integrated research of volcanic rocks and their sources. 2 analysis of TM images suggests the Tuoyun basin is a basin with a volcano group instead of a simple volcano-tectonic basin. We found several volcanic craters and cone, and detected three such craters. 3 systematic reseach of volcanic sections and collection of samples both of volcanic rocks and xenoliths, the later includes peridotite, granulite, gneiss and variety of megacrysts. This is propitious to our further research at this rigion. We would like to point that we collected some peridotite large than 20cm in diameter. It could used to variety of analysis and end the history without mantle chemistry records in the region. 4 we got a U-Pb SHRIMP age of 3.87 Ma for the Kangxiwa basalt.It is the youngest record of U-Pb SHRIMP age in China and provide a chronology restriction for last uplifting of Tibet plateau. 5 the investigation of alkali syenite-synogranite in Taxkogan suggests that the origin of Parmir syntex is related to the Cenozoic magmatism.

本项目立足于从火山岩属性和深源捕掳体反演源区成分与结构两个途径，利用火山岩综合研究成果对地幔源区进行了初步反演，提出源区经受过强烈钾质交代的观点；对重点工作区TM图像进行了初步解译，新发现若干了火山口，并对其中三个火山口作了实地查验，为进一步全面深入开展该区的火山地质学及相关科学问题打下了良好基础，认为托云盆地是一个火山群，而不是一个单一的火山构造盆地；系统测制了火山岩剖面，新采集了一批重要的火山岩和深源岩石捕虏体样品，为下一步工作打下基础，特别是采集到了直径打20cm的幔源橄榄岩包体，可用于各种测试，将可以结束西部造山带没有地幔岩化学分析结果的历史；对康西瓦玄武岩进行了测年分析，取得了我国目前最年轻的锆石U-Pb SHRIMP年龄，对青藏高原挽近地质时期的隆升提供了年代学约束；对帕米尔东缘塔什库尔干碱性岩体的动力学意义进行了探讨，提出青藏高原西部构造结的形成与岩浆活动有关的观点。

First, some seismotectonic belts in southeast and northeast Qinghai-Tibet Plateau which have similar geodynamic background are selected.

本文从地震地质学角度出发，充分利用地震学和岩石力学等学科中的相关研究理论和方法，将地震活动与具体的地震构造相结合，探讨了包含多个孕震区或断裂带的大陆板内地区的地震复发规律，提出了大陆板内地震的准周期丛集复发模式，并系统、全面的研究和讨论了不同断裂之间的相互作用及其对活动断裂地震危险性的影响，从机理上揭示了大陆板内地震准周期丛集复发行为的内在物理基础。

Strontium isotope stratigraphy relies on the fundamental principle that the marine strontium is isotopically homogenous world-wide at any time and the 87Sr/86Sr ratio of strontium in seawater of geological history has varied through time. By means of the 87Sr/86Sr ratio of marine carbonate which should record the original composition of sea water, we can date the marine sediments, research global events, such as history of basin subside, sea level change, orogenic events and palaeoclimate variation.

锶同位素地层学根据地质历史中的任何时间全球范围内海水的德同位素组成都是均一的、海水87Sr/86Sr比值随时间变化这一基本原理，利用代表原始海水的海相碳酸盐的87Sr/86Sr比值确定海相地层的年代，研究海平面变化、造山运动、古气候等全球事件，在地层学、沉积学、石油地质学和矿床学等领域中有着广泛的应用前景。

Lingnan first hurdle"- mei Guan, Zhang Jiuling for granted since the Tang Dynasty were excavated yidao phase, after the Central Plains of the arteries leading to Lingnan, the older generation of proletarian revolutionaries of Chen Yi's immortal poem,"Meiling three chapters of" also was born in This; well-known at home and abroad Abas Lane was once the southern border of the colony to expand the Chinese nation and the many people and Haiwaichizi Guangfu the birthplace of its unique cultural history, the Lingnan exerted a far-reaching economic and cultural impacts; in the urban areas of the three Shadow Guta in Guangdong Province, may be the only absolute test of the Song era tower, still majestic still existent; an area of 1800 square kilometers of "Nanxiong red layer, is the world's rare, one of the standard layer, where dinosaurs and other palaeontological is extremely rich in fossils, geology and paleontology of the research has important scientific value; being implemented to develop, with Danxia geomorphological features, Cang Shizhaishan natural scenery tourist area and scenic setting.

岭南第一关&——梅关，自唐代名相张九龄奉旨开凿驿道后，成为岭南通往中原之要道，老一辈无产阶级革命家陈毅的不朽诗篇《梅岭三章》也诞生于此；闻名海内外的珠玑巷一度是中华民族拓展南疆的聚居地和众多广府人及海外赤子的发祥地，其独特的人文历史，对岭南经济文化产生过深远影响；位于市区的三影古塔是广东省唯一有绝对年代可考的宋塔，至今雄姿犹存；面积达 1800 平方公里的&南雄红层，是世界上不可多得的标准层之一，其中恐龙等古生物化石极为丰富，对地质学和古生物学的研究具有相当重要的科学价值；正实施开发、具有丹霞地貌特征的苍石寨自然风光旅游区，景色怡人。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
