The paper divided turbidite fan in deep water from long source into braided channel microfacies , inter - braided channel microfacies , medium fan over - belt microfacies , and external fan subfacies , and divided slump turbidite which related with delta into medium fan subfacies and external fan subfacies , and summed up 15 kinds of marking of subfacies and microfacies classification . at the same time , it formed a series of effective technology of analyzing turbidite source at the base of studying region geological which combined with analyzing the content change of terrigenous debris , with the found of logging facies , and with the ancient terrestrial magnetism test and other technology means under the guidance of three - dimensional model of turbidite which has been founded already and the flat surface feature of microfacies 将远源深水浊积扇划分为辫状水道微相、辫状水道间微相、中扇过渡带微相和外扇亚相；将与三角洲有关的滑塌浊积扇划分为中扇和外扇两个亚相，并总结了浊积岩沉积划分各种亚相、微相类型的十四种标志，分别为:岩石类型、层理类型、砂岩单层厚度、粒度结构特征(粒度中值、分选性、概率曲线) 、生物化石、储层物性(孔隙度、渗透率) 、泥岩隔层特征(泥岩单层厚度、层数、颜色) 、鲍玛层序组合和自然电位曲线特征。
However geological information is fully recorded in the remote sensing image , which made it possible for the choosing of this area as a dissection point to extract complex structural information of orogenic belt in west china . taking fully advantage of multi - band image richly bearing concealed geological information in combination with remote sensing analysis and structure analysis , to anatomy the supracrustal composition and structure of orogenic belt with the regional linear structures and their partitioned block and schistous geological masses as the macro - frame ( in corresponding to structure units and structure segments ) and with the rock masses , structure - rock assemblages , line - featured and belt - featured structures as well as penetrative and non - penetrative foliation ( primary stratum and trans position layering ) and folds as the texture and structure elements . the methods of how to distinguish granulite > ductile - shear zone , imposed fold , different deformed belts - 因而，本文选择这一地区作为我国西部地区从遥感图像上提取造山带复杂结构构造信息的解剖区，充分利用遥感图像多波段反映物质属性的特点和图像处理提取隐含信息的优势，采用遥感解析?构造解析相结合的研究方法，以区域线状构造及由它划分的块状、片状地质体为宏观骨架(对应于构造解析划分的构造单元、构造均匀区段) ，以地质体中的岩石岩体、构造岩石组合，线状、带状构造，透入性、非透入性面状(原始层理、新生面理)和褶皱等构造作为用于解析的结构构造要素，进行造山带表壳组成和结构构造解析研究。
Furthermore , sorting of the sandstones in the braided river is better compared with that of in the meandering river system . in the same subfacies , grain size is larger and sorting is better in the channel sandstones which developed with large - scale cross - beddings such as trough cross - bedding , compared with sandstones in the flood microfacies . in the same microfacies , better sorting and coarser grained sandstones are distributed in the middle and lower part of the unit 与曲流河亚相相比，辫状河亚相砂岩的粒度较粗，分选性较好，砂体多次叠置而规模更大；相同河流亚相的河道微相与泛滥平原微相相比，前者的砂岩粒度较粗、分选性较好，发育槽状交错层理等大型层理构造；在同一微相内，处于中下部的流体单元其粒度较粗，分选较好。
At first it analyzes the bedding rock slope ' s bedded rock and its incontinuity face , and studies the stress , strain , stability ' s condition of the bedding rock slope , fully considering the cohesive force of rock layer and incontinuity face . geologic mechanics models of two types of bedding rock slope are set up , the instability coefficient of bedding rock slope under different mechanical parameters is computed , and the conclusion that the stability of bedding rock slope is relation to rock layerer , cohesive force of incontinuity face , inner friction angle and rock layer obliquity has been gotten . based on the above discussion , the thesis comes down the influence of rock layer and the incontinuity face on the bedding rock slope to incontinuity face ' s influence factors , and discusses other factors that influence the bedding rock slope ' s stability , so gains the evaluating and forecasting index marks 本文首先对顺层边坡的层状岩体及其中的层理面和不连续面进行了分析，对其应力应变进行了研究，得出了顺层边坡的稳定性不仅与岩体中岩石的强度有关，还与岩体中层理面及不连续面的内聚力、内摩擦角及其倾角有关；论文建立了层理面和节理面的地质力学模型，讨论了其力学参数变化对边坡稳定性的影响，并在此基础上将层理面和节理面归纳为顺层边坡稳定性的结构面影响因素，同时讨论了影响顺层边坡稳定性的其他因素，从而得出顺层边坡稳定性的评价预测指标。
