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。

I read Claus Sendlinger's editorial in Choupana Hills, a Design Hotel in Madeira that makes no special claim to greenness, though its light bulbs are low-energy, its toiletries come in recycled packaging and its decor involves products from the island: basalt and wickerwork from the nearby village of Camacha, one of the many local industries tangentially dependent on tourism.
森德林格的一篇社评Choupana Hills酒店是Design Hotels酒店在马德拉群岛的成员酒店,并没有刻意标榜绿色环保,尽管安装有低能耗照明灯,卫生用品使用的是再循环包装,装饰材料产品也都来自岛上:玄武岩制品和柳条制品来自附近的Camacha村当地许多行业都多少要依赖旅游业

The sharp difference suggests that they have different origins: the former comes from allochthonous sapropel-type organisms of the lower strata and is the remains of crude oil, and the latter is autochthonous humic-type organic matter of sedimentary rocks between the basalt layers.
玄武岩中铜矿石沥青的δ13CV-PDB为-27.3‰~-33.2‰,平均-31.97‰,沉积岩中铜矿石碳质的δ13Cv-PDB为-20.2‰~-23.2‰,平均-22.11‰,表明二者无明显成因联系,前者属腐泥型,为石油的遗迹,来自下部地层;后者为腐植型,来自原地沉积的陆生高等植物。

In addition, the features of elemental geochemistry of all samples suggest that (1) the EarlyTriassic andesitic rocks, characterized by characteristic natures of island arc volcanics, likely erupted in the subduction setting; that (2) the generation of LateTriassic rhyolites with an affinity of Alike granite and synchronously main body granites in the Lincang batholith displaying similar geochemical features, is closely related with the postcollision or latecollision setting; that (3) although the LateTriassic basic rocks partly show island arc volcanics such as highAl contents and NbTa depletion, some of them possessing highMg contents and mostly having traceelement ratios similar to intraplate basalt, which indicates that they erupted in the postcollision rift environment.
元素地球化学特征表明,早三叠世火山岩具有典型的岛弧火山岩的特征,暗示其很可能形成于俯冲的构造环境;中三叠世晚期的流纹岩与临沧花岗岩基主体具有非常相似的地球化学特征,结合其流纹岩具有A型花岗岩属性,表明该区中三叠世火成岩形成于碰撞后的构造背景;而晚三叠世基性火山岩虽然在地球化学特征上显示出与岛弧火山岩相似的高铝和NbTa的亏损,但其中部分火山岩具有高镁和板内玄武岩的微量元素比值特征,说明这些火山岩可能形成于碰撞后裂谷环境。
