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。

According to metamophic core complexes, syn-tectonic intrusive rock and its isotope dating data, divide Songliao basin evolution history into three stages: 1 orogenic period land-land collision; 2 post orogenic period mantle delamination, metamophic core complexes uplift and collapse extension; 3 weak extend stable depression in continent.

Occurrence of tectonic heat event on late-Mesozoic in Ordos basin result from intensive thermal mobility of deep lithosphere on the late-Mesozoic,Thermal mobility of deep lithosphere in sourth region is stronger than in north region. Mantle occur underplating and thickness of lithosphere reduce, magma invasion and eruption occur on late-Mesozoic. Ordos basin be in weak extension environment on late-Mesozoic.

鄂尔多斯盆地中生代晚期构造热事件发生的根本原因在于中生代晚期岩石圈深部的热活动增强，盆地南部岩石圈深部热活动性更强，早白垩世鄂尔多斯盆地处于一种弱拉张的构造环境，地幔发生底侵作用，岩石圈减薄，发生岩浆侵入和喷发。

It has the metamorphic rock sight—"the Inartificial Gallery" which is black and white, devious and whirlabout and likes the reversal cloud-mist and rising sun, the granite vein injecting along the bedding of gneiss crossing the river-gorge—"the White Dragon Crossing River", nine veins apposing on the rock wall—"the Nine-dragon Wall","the Inartificial Wall " formed by the paragenesis of the level joint and the vertical joint, and the small and exquisite undercutting cave which is the wonder of the new tectonic movement.
