地质学

The use of remote sensing technique in tectonics is a successful domain in geosciences applications.

遥感在构造地质学中的应用是遥感地学应用的比较成功的领域之一。

It is also used to investigation of the Paleo-Tethys tectonics in SE of Yunnan Province.

地球化学数据的计算机处理在地质学研究，尤其是大地构造学研究中也越来越彰显出其优越性。

The theory of uniformitarianism became the "time" foundation for the Theory of Evolution and the "Origin of the Species" book by Charles Darwin, which further discredited the Bible.

在1800年前后，当地质学作为充满活力的科学出现后，关于地球变化的另一种观点—"均变论"开始得到了发展。

The target function's optimal velocity is high, so it can boost learning efficiency of feedforward neural networks.

1引言定量地质学研究的基本要求之一，是在解决各种地质问题时，给出基于地质准则的数学准则。

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 John Walther, a professor of geology at Southern Methodist University, Lagos grew by 4,761 percent between 1950 and today.

据约翰沃尔瑟，地质学教授在南方卫理公会大学，拉各斯增长了4761和1950年之间的百分之今天。

To show that there had been enough time for natural selection to work slowly, he again cited Principles of Geology and other observations based on sedimentation and erosion, including an estimate that erosion of The Weald had taken 300 million years.

为了表明有足够的时间让自然选择慢慢地进行，他再次引用《地质学原理》和其它基于沉积和侵蚀的观察资料，包括对威尔德原野侵蚀为三亿年的估计。

China Fantastic Black" is a special type of granite, geologically in petrology, it mainly contains "ankaramite, if polished or water-washed, its slab presents background in dark black with big crystals in ingotism structure. It reveal itself a special optical effect of reflecting both golden and blue colors with interreaction in change which can only be seen from some precious stones ___ fresh and novel to eyes.

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
