| 1. | The formation and evolution of liaohe meso - cenozoic basin were controlled by the variation of different regional stress field
摘要中新生代辽河盆地的形成和发展受控于多期区域应力场变化。 |
| 2. | The inversion confirms that plate boundary actions are main factors controlling the regional stress field , and spreading forces of mountains and seashores are another important factor
同时显示了板块在垂直载荷下的弯曲对局部水平应力场造成相当的影响。 |
| 3. | According to guibin - zhang et . recent research hi this aspect , we propose a model in which the mountain root and lithoshpheric root may contribute more to the regional stress system in collision mountain ranges
Bott 、高锐和张贵宾等一批学者已经从理论或数值模拟方面对岩石圈根进行了研究，在这些研究的基础上，本文明确提出岩石圈根拖曳模式。 |
| 4. | The variation of regional stress field can be genetically interpreted by the rotation speed variation of the earth and its impact on the movement of lithosphere plate and deep processes of the earth , it is also related to the earlier structural feature and boundary of the basin
区域应力场变化可以用地球自转速度变化引起的岩石圈板块活动及触发的深部过程来解释，亦与先期构造形迹和盆地边界条件有关。 |
| 5. | The surface loading of the mountains and the associated root of thickened crust produce horizontal deviatoric tension in the strong upper crust . in contrast , the deep , dense lithospheric root and its associated downflexing of the surface produce horizontal compressive deviatoric stress in the strong near - surface layer . the actual state of stress in the strong layer of the upper crust is the combined effect of these two opposite stress systems together with bending and other local and regional stresses such as due to ridge push
模拟结果表明：由于均衡机制，造山带下部的低密度山根促使地壳隆升、造山，山根是地壳刚性层中张性构造应力的主要力源；与此相反，冷的高密度岩石圈向软流圈插入、拆离、下沉，从而形成岩石圈根，它引起挤压造山和岩石圈地幔物质的重新调整，也是地壳刚性层中挤压性构造应力的主要力源。 |
| 6. | In the process of same one regional stress field , the tectonic evolution and oil and gas geologic condition of kuqa foreland thrusting belt and the southern margin of junggar basin all show much similar characteristics , both of them developed multi - set mature source rocks , and formed multi - set high - quality reservoir - cover combinations , and developed various traps
天山造山带的形成与演化对于其两侧盆地的展布、基底性质、沉积盖层的规模、盆地整体结构特征、后期破坏等具有重要的影响和控制作用。 |
| 7. | Based on the analysis of thermal contact metamorphic aureoles , granitoid interior structure , quartz axis fabric and strain characters in the different rock unites of yuanshishan granitoid and its wall rocks , the emplacement mechanism of yanshishan granitoid was studied . the magmatic explictite dynamic was advanced in light of regional stress and magma dynamic research . those conclusion was synthesized to ascertain the emplacement mechanism - granitic magma ascended in dikes with the minimum critical width of the magma ascending channels about 2 . 213 . 88m and located in the core of yindianshan dome with the passive style of dyke explictite ; the later unite is a kind of multiple emplacement mechanism with the character of active emplacement of ballooning
同时运用岩浆动力学原理从另一个角度探讨其侵位驱动力。综上指出：经分凝后的活动性岩浆在深部侧向挤压和浮力的联合驱动下，沿深大断裂以最小临界宽度为2 . 213 . 88m的裂隙脉动上侵，整体以岩墙扩展的方式被动定位于银殿山穹窿的核部，但后期屋面前单元具有主动侵位的特点应为一种复合定位机制。 |
