Abundant peridotitic xenoliths had been found in the Dashihe Cenozoic basalts in Jiaohe of Jilin Province, northeastern China.

吉林省蛟河市境内大石河新生代玄武岩中含有丰富的地幔橄榄岩包体，详细的岩石学与矿物学研究显示，这些包体的主要岩石类型为尖晶石二辉橄榄岩-方辉橄榄岩，未发现石榴石橄榄岩。

Sanidinite (some have transformed to perthite) and quartz inclusions with radial cracks are often seen in the garnet of eclogite. The geothermal gradient of ＜10℃/km is recorded in the early stage mineral assemblage of high-pressure metapelitic rocks with relict aragonite. these features imply a possibility that there may be ultra-high-pressure rocks existed in Altun.

根据榴辉岩中石榴石常见透长石和石英包体，并有放射状裂纹的特征，以及高压变泥质岩石早期矿物组合温压条件记录的地温梯度小于10℃/km和残存文石等特征，不排除区内有超高压变质岩石存在的可能性。

Love, which seems the realest thing, is really nothing at all;a simple gray rock is a thousand times more tangible than love is; and the earth is such a rock, and love only a breeze that dreams over its surface, weightless and traceless.

爱，似乎是最真实的东西，但实际上根本什么也不是；一块素朴的灰色岩石也要比爱实际一千倍；尘世如同岩石，而爱仅仅是掠过它表面的一阵清风，没有重量、了无踪迹。

The purpose of paper is to describe the petrology character of outcrop sandstones and core sandstones and judge their roke type, compare the similarities and differences of autogenetic mineral、diagenesis types、intergrowth sequence、diagenetic facies、diagenetic phase of outcrop sandstones and core sandstones, provide academic precondition condition for studying better reservoir in studied region.

本次论文的研究目的是描述露头砂岩和岩芯砂岩岩石学特征并判断其岩石类型，比较露头砂岩与岩芯砂岩在自生矿物、成岩作用类型、共生序列、成岩相、成岩阶段以及成岩流体演化方面的异同，为研究区有利储层的研究提供理论前提条件。

The sand body of channel in the middle sublacustrine fan has good porosity and is favorable reservoir.

利用东濮凹陷桥口地区的地质、测井和化验分析资料，从沉积微相、成岩作用、岩石结构等多方面入手，对其储层物性特征和控制因素进行了研究，指出桥口深层气藏湖底扇中扇辫状水道砂体物性较好，为有利储集层；该储层孔隙类型以次生溶蚀粒间孔隙为主，岩石粒度较细、分选中—差、以点—线接触为主；片状或弯片状喉道所占份额较大，造成储层低孔低渗；受溶蚀和交代作用的影响，部分层位次生孔隙发育，深层中也存在物性较好的储层。

Evolution of rock joints into transfixion is described by the time series from strain-stress curves,and the state of joint system in sandstone is chaotic before its ultimate state.

形成岩石全应力应变曲线的时间序列反映了岩石内部节理裂隙趋向贯通的演化进程，砂岩节理裂隙系统在峰前阶段处于不同程度的混沌状态。

Field geological investigation, petrology and geochemistry study showed that three oil shale groups in Kazuo basin were developed in Member 1,2,3 of the Jiufotang Formation of Lower Cretaceous, the third oil shale group located in 3rd member have the greatest industrial significance. Oil shale always has the accompanying relationship with overlying sedimentary tuff or other tuffaceous strata.

野外地质调查和岩石学、地球化学研究表明：喀左盆地3个油页岩层群分别发育于下白垩统九佛堂组的一、二、三段，以位于三段的第三油页岩层群的工业意义最大；油页岩常与上覆沉凝灰岩或其它凝灰质岩石呈伴生关系。

Also, tropical rocks tend to experience deep weathering, rarely poking above the ground as outcrops.

而且，热带区域的岩石往往要承受更为严重的风化作用，很少有类似岩石露头的情况发生。

Petrological and geochemical characteristics of alkali-rich porphyries suggest that magmas might not be generated from subducted oceanic slab, but likely from the base of thickened crust, corresponding to eclogite-facies.

富碱斑岩产出的地质背景及岩石学和地球化学特征表明，富碱斑岩并非起源于俯冲的大洋板片，而是源于加厚地壳的底部，源区为榴辉岩相岩石。

According to this scheme, the Longmaxi Formation is only referred to as the black siliceous and carbonaceous shales at the base of the Silurian strata. All the carbonate rocks above it have been redelineated and redivided into new lithostratigraphic units.

新方案除对志留系底的黑色硅质碳质页岩沿用龙马溪组这一岩石地层单位名称外，其上的碳酸盐岩均重新划分和建立了新的岩石地层单位，并确定其涵义和时限标准。

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。
