劈理

P65 Cleavage: It is related with deformation and metamorphism, and developed in rock layers or rock bodies.

劈理：与变形变质作用相关，发育在岩层或岩体中，表征密集排列的微破裂或潜在的面状构造。

It is, in fact, concerned with foliation, flow surface, schistosity

实际涉及面理、流面、片理、片麻理、劈理和各种破裂面等类型。

Because slack has changed the underground water condition which led to the gathering of underground water at the mudstone cleavage zone, and has decreased the resistance, of which the synthetic 〓 is about 13°, it has made the rock mass about the cleavage slide slsde in the western direction.

从边坡岩体地质力学调查分析、岩体结构分析和采煤对滑坡的影响分析，得出滑坡形成的机理，采煤使P〓岩层中沿NW10°~20°/W15°劈理带贯通而移动，由于松弛改变了地下水条件，使地下水向之集中，该泥质劈理带在过水下摩阻力降低，其综合φ为13°左右，使上覆岩体沿之向西滑动。

For giving an explaintion of strong transmogrification but feebleness metamorphism of and their corresponding relation of the Triassic stratum in Songpan-Ganzi area and opening out the temperature and stress condition, this paper summarized study production of predecessors, and put forward 5 conclusions about Songpan-Ganzi area Triassic main lithology(slate, sandrock,and blastopsammitic) through field geological investigation , actual measurement section plane study and combining indoor slice identification , electron probing and fluid enclosure testing analysis:1.Field outcrop strongly transmogrification, and often developed same cleavages(S1) erection or approximately erection 'B'fold and symmetry similituded fold. 2.The metamorphosed mineral combination is simple, and the typical metamorphosed mineral combination is Al+Chl+Ser+Cc+Q, etc. The metamorphosed mineral develops mainly along the cleavages of the territorial cleavages faces(S1), bearing territorial dynamic metamorphism character and belonging to the lawsonite-albite-chlorite face of slightly metamorphism. 3.Territorial metamorphism P-T change focus on T:180～200oC, P:1～2kbar

为了对松潘-甘孜地区三叠系强变形浅变质的特征及变质与变形的对应关系作出解释，揭示变质与变形的温-压条件，本论文总结前人研究成果，通过野外地质调查和实测剖面研究，结合室内薄片鉴定、电子探针和流体包裹体测试分析，对松潘-甘孜地区三叠系主体岩性(板岩、砂板岩、变质砂岩及千枚岩)的变质作用得出5 个认识结论：1、整个松潘-甘孜地区经受了自北向南的强大挤压；2、变质矿物组合简单，除雏晶黑云母外，典型的变质矿物组合为Al+Chl+Ser+Cc+Q等，变质矿物主要沿区域性劈理面(S1)的劈理域发育，具有区域动力变质作用特征，属于低级变质作用中的硬柱石-钠长石-绿泥石相；3、区域变质作用P-T 变化集中在T：180～200oC，P：1～2kbar

Particularly in strongly deformed areas, various typesof cleavages often exist in large scale folds, faults and ductile shear zones.

在变形强烈的地区，各种劈理往往产出于更大规模的褶皱，断层和韧性剪切带中。

The stress field analysis showed that the cleavages formed under horizontal, S-N trending compressive stress.

应力场的分析表明，劈理构造由近南北向的地壳水平挤压应力作用形成。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
