在贺兰山的中生代地层中，晚三叠世-中侏罗世地层分布广泛、厚度巨大，中侏罗世延安组为贺兰山的优质含煤层。 |
| 4. | Great many mesozoic basins in which mesozoic sediments had certain depth and early - mid jurassic strata were broadly distributed are found nearby western ordoa basin
盆地西邻中生代盆地发育，各盆地均有一定厚度的中生代沉积，其中以早中侏罗世地层分布最广。 |
| 5. | In this paper , on the basis of detailed outcrop and core observation , as well as the logging and seismic data , the high resolution sequence stratigraphy method has been applied to the west sichuan jurassic strata systematically
本文在详细的野外露头、岩芯观察的基础上，结合测井和地震剖面资料，对川西侏罗系地层进行了较为系统的高分辨率层序地层学研究。 |
| 6. | Researches show there are many types of strata pressure , super pressure in certain depth below the bottom of the jurassic stratum , and also overpressure in the whole jurassic stratum in central and southern of mosuowan salient
研究表明该地区地层压力类型丰富，侏罗系底部及以下地层在凹陷内一定深度以下普遍发育高压，在莫索湾凸起的中南部侏罗系则整体处于超压状态。 |
| 7. | ( oxifordian - kimmeridgian ) , xueshan fm . ( tithonian - berriasian ) . according to field investigation , thin section identification and many other methods of sedimentary petrology , rock types of jurassic strata include carbonates , argillaceous rocks and clastic rocks

| 8. | Kongxi buried hill shows following features in the seismic profiles : the structures are asymmetric . there is flexural syncline on the east side and a monocline on the west side . asymmetric repetition of stratigraphic units is present in the drill wells and the dips of beds and faults are gentle . the permo - carboniferous system of both sides almost lie in the same slope and the events of cambrian or upper proterozoic are continuous from east to west . the phenomenas suggest that kongxi buried hill could be a thrust belt been traced which consists of reverse faults . the imbricate faults mainly effect pre - jurassic strata . there are obvious angular unconformity between jurassic - cretaceous system and paleozoic involved deformation of thrust . the thrust front in some place has cut off the beds of jurassic - cretaceous system . the structural style of the thrust structure changes along the strike of the kongxi buried hill
地震和钻井资料揭露的孔西构造带前第三系潜山的地质特征可以归纳为：构造带总体上不对称构造带内部有地层重复现象石炭二叠系地层的位置明显高于两侧的同一地层的高度。用由34条向东倾斜的逆冲断层组成的叠瓦扇构造模式能够比较合理地解释上述地质特征。该带向东倾斜的逆冲叠瓦状断层组主要影响前侏罗系地层，侏罗白垩系与卷入逆冲构造变形的古生界地层之间有明显的角度不整合。 |
