Their petrological and lithogeochemical characteristics show of typical shoshonites.

岩石学和岩石化学特征显示典型的钾玄岩特征。

The actual chemical make-up of rocks is complex, so the conventions of petrological analysis pretend that these metals are present in basalt as their oxides.

然而构成这种岩石的化学元素十分的复杂，因此根据常规的岩石分析得出出现在玄武岩里的金属都是其氧化产物。

On the basis of P-T estimated results and geophysical data, the petrological zoning model of Mesozoic lithospheric mantle in eastern North China block is set up in the thesis.

依据深源岩石包体的P-T条件估算结果，结合地球物理测深资料，本文建立了华北地块东部中生代岩石圈地幔的岩石学分带模型。

A detailed geological, isotope chronological, petrological and geochemicalstudy combined with collection and sorting out of relevant data has been carried out on thegranitoids.

本文系统收集和整理了相关地质资料，并对区内中生代花岗岩类进行了较详细的地质学、年代学、岩石学和岩石地球化学研究。

The ultra-high pressure metamorphic rocks distributed in the southern Dabie Shan have different rocks types including eclogites, garnet pyroxenite and garnet peridotite, quartz jadeitite, acid gneiss, phengite- quartz schist and marble.

分布于大别山南部的超高压变质岩具有丰富的岩石组合，主要岩石类型有榴辉岩、石榴辉石岩和石榴橄榄岩、石英硬玉岩、酸性片麻岩、多硅白云母石英片岩及大理岩等。

Based on this review, authors indicate that the readjustment of mineralogical and chemical compositions and volume changes are the main research areas of the fluid action in ductile shear zone. The study on the fluid action in ductile shear zone will be carried out in the following aspects: evolution history of tectonicfluid, tectonic physicochemistry, and the strain model and its features.

本文在综合评价现有研究成果的基础上认为，岩石的成分变异和体积变化是韧性前切带内流体作用研究的主要内容，韧性剪切带内构造－流体演化历史，构造物理化学、岩石应变模式及其特征的研究是今后韧性剪切带内流体作用研究的发展方向和前沿领域。

本文在综合评价现有研究成果的基础上认为，岩石的成分变异和体积变化是韧性剪切带内流体作用研究的主要内容，韧性剪切带内构造-流体演化历史、构造物理化学、岩石应变模式及其特征的研究是今后韧性剪切带内流体作用研究的发展方向和前沿领域。

Finally, the GPSE strength criterion for rock is verified by polyaxial test data of brittle rocks. The strength criterion for rock can be widely used to brittle rocks and allows for a good description of the several effects of stresses mentioned above, nonlinear characteristics of strength and marked difference for tensile strength and compression strength.

最后，通过对不同种类岩石多轴试验结果的验证分析，表明该准则能够较为合理地描述上述4种效应，而且能够反映非线性强度特征和拉压强度的显著区别，可广泛地适用于各种性岩石。

porphyritic granite ; the uniaxial compressive strength ; scale effect ; stability test

而岩石单轴抗压强度试验，人们认为这是最简单、最常规的岩石力学测试项目之一，但就试

The comparison of petrology, lithofacies, petro-geochemistry and tectonic environment of the rapakivi granite both from Qinling-Kunlun and world shows that the rapakivi granite has same or consistent characteristics: rapakivi structure, sub-aluminous, high-potassic, alkali-rich magma, two-peak magma assemblage and formed in post-collision environment. However, there are some certain differences in some geochemical index, forming age of magma, and geotectonic position of outcropping.

通过秦岭－昆仑造山带中的环斑花岗岩同世界元古宙环斑花岗岩的岩石学、岩相学、岩石地球化学和构造环境等方面的对比研究发现，二者具有相同或一致的特征：具环斑结构，属准铝、高钾、富碱岩浆，具双峰式岩浆组合，形成于后碰撞环境，但其地球化学的某些指标、岩浆形成时代和出露的大地构造位置等有一定差异。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
