片岩的

There are much discontinuities in rockmass, they have different, different character, different dimension and different orient. For example, bedding plane, unconformity, schistosity, fault, fissure,etc.

岩体中总是存在着各种成因不同，性质不同，大小不同和产状不同的结构面，如层面、不整合面、片理面、断层、裂隙等。

The morphology, occurrence and components of dawsonite were described, and the paragenetic sequence of sandstone and origin of CO2 forming dawsonite were investigated by polarization microscope, scanning electron microscope, Xray diffraction and MAT251 stable isotope mass spectrometer.

利用偏光显微镜、扫描电镜、X射线衍射分析仪和MAT251稳定同位素质谱仪，详细描述了片钠铝石的形貌、产状和成分，确定了含片钠铝石砂岩的成岩共生序列和形成片钠铝石的CO2的成因。

Dawsonite is an orthorhombic, hydrated sodium aluminium carbonate appearing as radial, bunchy, trichoid platy collective and so on, filling in the pores among the grains, or as replacement of feldspar and detritus partly or on the whole, dawsonite is a kind of authigenic mineral which formed latest.

片钠铝石是一种斜方晶系、含水、钠和铝的碳酸盐矿物，砂岩中的片钠铝石是最晚形成的自生矿物之一，一般以放射状、束状、毛发状、板状等分布于砂岩的孔隙中或交代长石和岩屑等。

Dawsonite in the shapes of foliated columnar, cluster, radial, chrysanthemum or random hair mainly filled in the intergranular pores as cements and a few replaced grains such as feldspar and quartz.

其中，片钠铝石呈板柱状、束状、放射状、菊花状、杂乱毛发状集合体，主要作为胶结物产于碎屑岩碎屑颗粒间的孔隙中，少量交代长石、石英等碎屑。

I think the foliation is resulted from deformation . The original composition of the foliated rock is granite.

我认为岩石中的这些片理是由于岩石变形造成的，片理化岩石的原岩就是花岗岩。

I think the foliation is resulted from deformation.

我认为岩石中的这些片理是由于岩石变形造成的，片理化岩石的原岩就是花岗岩。

"One scientist called it a time capsule of reef building," said Linda Fitch of the Isle La Motte Preservation Trust.

莫特岛地质保护信托基金会负责人琳达·菲奇说：一位科学家将这片巨型岩称作是一座存放时代特征物品的岩石建筑。

I think the foliated rocks within the belt are mostly mylonite.

我认为在这个片理化带中的大多数岩石都是糜棱岩。

Combined with the project of'Technology of ground pressure control under high crustal stress and the mining plan research in Yinshan Mine', the stability of schistosity structural stope is studied.

主要研究内容和结论如下：(1)在现场调查的基础上，进行了工程地质岩组划分，查明了保护墩及采场片帮、冒顶的主要原因，得出了片理结构是影响采场稳定性主要因素的结论。

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。

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。
