A good many mico-landblock of the early Neoproterozoic-Cambrian volcanic rock that distribute in the Tianshan orogenic belt and on its both sides, and the Carboniferous-Permian volcanic rocks that widely distribute in the Tianshan and adjacent regions are selected for subject investigating in this paper. Renewing the ocean-land format and ocean-land conversion process of Tianshan orogenic belt in the Paleozoic is the masterstroke for this paper. On the basis of detailed field investigation, many subjects, such asregional lithology、geochemistry、structural geology、volcanic sedimentology geology、sotope geochronology and synthesis analysis study of geophysics data, are adopted as instrumentality in the paper, this study lays emphasis on the formation, evolution and dynamics of early Neoproterozoic-Cambrian and Carboniferous-Permian volcanic rock in the Tianshan and its adjacent regions to find out Carboniferous-Permian volcanic rock property, eruptive sequence, time and space distribution characteristics, to resume and reconstruct evolution process of Carboniferous-Permian volcanic rock, and to explore connection of magmatism process and lithosphere stretching action of neopaleozoic ocean-land transformation in the Tianshan region.

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.

Integrated analysis of 7 times heavy rain in Yunnan from July 19 to August 2 based on actual observation weather datum and satellite cloud atlas and Doppler radar image. The results show that: high-low southwest jet stream is important effect system. The maintenance of southwest jet stream provides water vapor, momentum, fast transfer of unstable energy for the lasting heavy rain. The further configuration of plateau shear line and southwest jet stream is necessarily condition about 7 times heavy rain. The lasting heavy rain appeared on big value region of 500hPa vapour flux and vapour flux divergence. The shear cloud band and subtropical high cloud band crossed and confluenced in Yunnan on the satellite cloud atlas. The maintenance and intensification of shear cloud hand and periphery cloud band of subtropical high correspond quite well to heavy rain falling region and cloud band distribution.

应用实测气象资料，结合卫星云图与多普勒雷达图像分析，对2007年7月19日到8月2日云南少有的7次强降水过程进行综合分析，结果表明：高低空的西南急流是重要的影响系统，西南急流的维持为持续性强降水过程提供了水汽、动量和不稳定能量的快速传递，高原切变线与西南急流的有利配置，是7次持续性强降水过程必不可少的条件；持续性强降水出现在500hPa水汽通量大值区和水汽通量散度辐合区；卫星云图上切变云带和副高外围云带在云南汇合，切变云带和副高外围云带维持、加强的过程与强降水落区的时空分布对应较好。

Kalamaili suture zone is an important plate boundary in north Xinjiang, and there are plenty of Neopaleozoic volcanic rocks around itThese volcanic rocks are enriched in LILEs and relatively depleted in HFSEs, and they are also characterized by high Nb, Zr, TiO2 contents and Zr/Y, Nb/Y ratios, and depleted SrNd isotopesThe characteristics of these volcanic rocks suggest that they were produced in postcollisional periodThe postcollisional volcanic rocks around Kalamaili suture zone become younger from west to east, which indicates that this suture zone entered postcollisional period gradually from west to east, and reflects that the Kalamaili Ocean had been closed gradually from west to eastAs to the Kalamaili suture zone in postcollisional period, the lithosphere extended and thinned, and the asthenosphere materials upwelled and melted partially, and intensive mantle convection occurred, leading to a plenty of mantlederived magmas underplating the suture zoneThe lithospheric mantle metasomatized by fluid in subduction period melted partially under decompression and high temperature, the resulting melts contaminated the underplating asthenospheric materials, and the erupted lavas became the Neopaleozoic postcollisional volcanic rocks

卡拉麦里缝合带是北疆的一条重要界线，沿该带广泛发育晚古生代火山岩。这些火山岩具有LILE相对富集、HFSE相对亏损的特征，且具有较高的Nb、Zr、TiO2含量和Zr/Y、Nb/Y比值，SrNd同位素主要表现出亏损的特征。综合分析表明，这些火山岩形成于后碰撞期。对卡拉麦里缝合带而言，从西向东后碰撞火山岩的时代逐渐变新，表明该缝合带从西向东逐渐演化进入后碰撞期，这从侧面反映了卡拉麦里洋盆是从西向东逐渐关闭的。对卡拉麦里缝合带而言，在后碰撞期，岩石圈伸展减薄，软流圈地幔物质上涌并发生部分熔融，加上地幔对流作用强烈，使得缝合带下产生了大规模的幔源岩浆底垫；先前在洋壳消减期被流体交代提取过的岩石圈地幔也在低压高温下发生部分熔融，形成的熔体混染了底垫的软流圈物质并喷发，形成了晚古生代的后碰撞期火山岩。

The flow field construct of meso-β cloud clusters which bring the heavy-hard rainfall in northeast plateau is that the low level cloud cluster is located in the south of converging region, the southern low level influx converged in the cloud cluster and have some affection on the setting up of the rainstorm in the low level. In the middle level, the cloud cluster is lied in near the westerly trough and the southwest airflow ahead of the trough constantly transmits water vapor to the cloud cluster. In the high level, there are a pair of high and low pressure centers around cloud clusters and are obvious divergence airflow, and there is weak ageostrophic high level outflux along pressure force.

产生高原东北部地区大到暴雨天气过程的中—β尺度云团的流场结构特征是：在低层，云团位于辐合区的南部，低层的偏南低空入流在云团内辐合，对大到暴雨的形成有一定的作用；在中层，云团位于西风带低槽附近，槽前的西南气流不断地给云团输送水汽；在高层，云团附近有一对高、低压中心，为明显的辐散气流，沿气压梯度力方向有强度不强的非地转高空出流。
