| 1. | Microstructures and ages of activity of the reverse faults along the southern margin of the junggar basin 准噶尔盆地南缘断裂带显微构造特征与活动时代 |
| 2. | Structural features and evolution of contemporaneous reversed faults in gas faulted depression in western qaidam basin 柴西地区尕斯断陷同生逆断裂构造特征与形成演化 |
| 3. | The most critical factors in evaluating and predicting such traps sealed by the reverse fault are the analysis of strike closure and the estimation of fault sealing 评价和预测此类圈闭的最关键因素是进行走向闭合分析和断层封闭性的评价。 |
| 4. | Based on the contrast of the comparability , the paper concludes that the footwalls of reverse faults in the front of altun mountain may form effective hydrocarbon traps 通过对比分析两者之间的相似性,认为柴达木盆地阿尔金山前带构造深部发育的逆冲断裂下盘也应该具有形成油气圈闭的条件。 |
| 5. | The research show that the formation of the fault is earlier than these klippen , but it is also a revived reverse fault after the klippen took themselves places from relationship between the fault and klippen , and the esr age determination 据断裂带与飞来峰压覆及切割关系和esr年龄,表明断裂的形成应早于飞来峰的就位,而飞来峰就位后断裂又有过再次的逆冲活动。 |
| 6. | The tectonic style inside the basin is characterized by occurrence of anticlines from the margins to center of the basin , with two limbs mostly starting from reverse faults , developing a tectonic pattern of two faults sandwiching an uplift 盆地内部的构造样式以自盆地边缘至中心以此形成背斜构造为显著特徵,背斜两翼多发育逆断层,构成“两断夹一隆”的构造格局。 |
| 7. | Analyzing the propagation behaviors for open and close crack , the author gain that normal fault is more dangerous to earthquake than reverse fault and glide fault . 3 . appling fracture mechanics to discuss reservoir - induce earthquake mechanism , the author observes the characteristic of surface crack and gains the stress intensity factor induced by the pressure of rock , water and osmosis 针对库区断层为表面裂纹这一特点,研究水库地震的断裂特点,得出地应力作用下的应力强度因子、库水作用下的应力强度因子和渗压作用下的应力强度因子以及它们的应力强度因子之合,并且合理的解释了构造型水库地震的诱发机理。 |
| 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。 |
| 9. | They are paleozoic ~ early mesozoic - fold deformation and the appearance of reversed fault ; mesozoic - the beginning of graben faulting - block period ; early cenozoic - the phase of broke - the forming of block hill ; late cenozoic - the phase of segging - the forming of buried hill . we mark off five kinds of buried hill belts . they include three different kinds of trap on the basis of the cause of trap formation 本次研究在重新认识济阳坳陷区域构造背景的基础上,将济阳坳陷古生界潜山的形成过程分为四个阶段,即古生代早中生代?稳定沉降?隆升?轻微褶皱变形及逆断层发育阶段、中生代?初步断陷阶段?块断期、新生代早期?断拗阶段?块断潜山形成期以及新生代晚期?坳陷阶段?潜山定型期。 |
