岩石学

The rutile-hosted rocks are metamorphic rocks with amphibolite facie, but more work should be done to discuss features of their protolith.

The main fruits of study are as follows:(1) A complete stratigraphic framework of Middle-Upper Jurassic series is set up through systematic stratigraphic study of Middle-Upper Jurassic by the analysis of lithostratigraphy , biostratigraphy and chronostratigraphy on five groups of Middle-Upper Jurassic series in the studied area.

主要成果表现在以下五个方面：(1)通过对研究区中—上侏罗统五个组进行岩石地层、生物地层和年代地层分析，系统进行中—上侏罗统地层学研究，建立了研究区中—上侏罗统完整的地层格架。

Based on the theory of Sequence Stratigraphy and the systematically analysis of strata which was closely focused on Lithostratigraphy, Biostratigraphy, Paleoecology Event Stratigraphy and Sequence Stratigraphy, four long-term base-level cycles can be recognized in the Mesozoic, each long-term base-level cycles can be further divided into intermediate-term to short-term base-level cycle. Eight intermediate-term base-level cycles are recognized in Mesozoic; Cenozoic can be divided into two structural base-level cycles, and can be further divided into seven long-term baselevel cycles.

应用层序地层学理论，在详细的岩石地层、生物地层、生态地层、事件地层和层序地层为核心的综合地层研究基础上，将中生界划分为四个长期基准面旋回，每个长期基准面旋回内部又可进一步识别出更次一级的旋回，侏罗系内部共可识别出8个次级旋回；根据钻井层序地层与地震地层划分结果，将北缘地区新生界划分为两个构造基准面旋回，其内部又可进一步划分为7个长期基准面旋回。

定量化火成岩结构分析将传统的定性或半定量化的岩相学研究，提高到了与岩石地球化学分析相比拟的定量化程度，实现了诸如晶体粒度分布、晶体空间分布、晶体定向程度分析和二面角测量等方面的定量化研究。

Synthetic material data and physical model analysis as well as experimental deformation contrast have demonstrated that the deformed gravel underwent the prolonged and simultaneous multi-boundary external force condition and the equilibrant system characterized by intensiveness and scattering.

中文摘要：经过多年的区域地质调查和第四纪环境演变的分析，对庐山芦林盆地大校场谷口剖面松散沉积物中变形砾石进行岩石显微构造学的研究。

Owing to the monotonic mapping of fuzzy structured element established the homeomorphic property between fuzzy number space and the family of standard bounded monotone function, so, we can transform the study of any properties in fuzzy number space to the corresponding one in the family of standard bounded monotone function, e.g.

本项目针对矿井下采空区岩石陷落形成的多孔隙介质空间的极度不规则性，建立一种以模糊值函数分析学为基础的、更接近于刻划采空区内气体流动实际状况的模糊微分方程及各种边值问题，进而得出解算复杂采场气体模糊渗流问题的数学方法。

By integrating the multi-discipline methods of petroleum geochemistry, sedimentology, hydrogeology, petroleum geology and experimental geochemistry, the thesis has carried out experiments of microcline dissolution in solutions with organic acids, crude oil, brines with high total dissolved solids , and has dealt with Al distribution between the crude oil and the brines after the experiments.

Charlotte Mehrtens, head of geology at the University of Vermont, has studied other portions of it from Newfoundland to Tennessee, but said Isle La Motte is the only place where so much of it is visible.

佛蒙特大学地质学系负责人梅尔腾正在研究这片巨型岩从纽芬兰岛到天纳西州的部分，但他指出，莫特岛地段的岩石是暴露在地面最多的部分。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
