| 1. | The research result shows that this physical model is useful to determine the locked area along plate boundary faults and further to make the long term and middle term earthquake prediction 研究结果表明,运用该模型方法可利用大地测量数据确定沿板块边界断层带的相对闭锁区,从而进行中长期地震预报。 |
| 2. | 4 ) analyses boundary faults of the cenozoic longmenshan foreland basin , and thinks the basin boundary faults , being active fault , are thrust and dextral strike - slip . so the longmenshan foreland basin is dextral strike - slip foreland basin 4 )通过对新生代龙门山前陆盆地边界断裂的考察分析,认为盆地边界断裂具逆冲推覆及右旋走滑作用特点,为活动断裂。 |
| 3. | The fault at the east boundary of tangyuan fault basin is a basin - controlling fault , and the faults at both the east and the west boundaries of fangzheng fault basin are also a basin - controlling fault , with the west boundary fault at fangzheng being the major one 断层的生长指数分析表明,依舒地堑内部的北西向断裂与边界断裂的活动具有一致的规律性,都起到协调边界断裂演化发展的作用。 |
| 4. | 1 based on the analysis of sedimentary structure and sedimentary energy , the facies model was founded . pucheng oil field is tightly adjacent to the boundary fault of dongpu depress , and it is easy to develop fan - delta and sub - fan on this location . in fact it is easy to find the sediment supply of the studying area is mainly from eastern high through the thickness map and its sand - content map 在研究层段共划分长期旋回1个、中期旋回6个和短期旋回27个(短期旋回规模太小,仅能在岩心上识别) ,通过测井曲线的基准面识别和对比,确定了地层的分布,结合基准面旋回内可容空间的变化,对其沉积演化进行了分析。 |
| 5. | Based on the synchronic seqence stratigraphic framework , through comprehensive investigation of the evaluation of seqence , the type of sedimentary facies and sedimentary system with it ' s area distribution , the domination of paleogeographic structure to paleocurrent and sedimentary system , draw a conclusion : the boundaries of the thickness of sequence was bounded by the boundary faults . the irregularity of sedimentary facies was dominated by base level rise to fall and accommodation 在建立等时层序地层格架的基础上,分析了层序的充填演化规律、沉积相和沉积体系的类型及其平面分布特征、古构造对古水流和沉积体系分布的影响,得出以下认识:层序发育的厚度受边界断层控制,层序内部沉积相的变化规律受基准面和可容纳空间的控制。 |
| 6. | By means of kiba formation , k . ibt " and kibt2 segments analysis on the equivalent time stratigraphic framework , subtle traps will be predicted on stratigraphic traps and lithological traps . the results from the research indicated that : ( 1 ) this paper further indicates the control significance of southern boundary fault displacement component , which downthrown side forms syncline or anticline , and points out that 4 anticlines in south are adjustment zone and are the entering lake position of ancient river 本论文的主要认识和结论如下: ( 1 )进一步认识南缘边界断层位移量对下降盘形成次凹或横向突起的控制意义,认出南缘的4个突起是调节带之所在,也是古河流入湖处。这种格局导致凹陷强烈分割,并以横向搬运为主。 |
| 7. | The hanging wall of sag extended in southeast direction , with the tulage fault being the boundary fault . yinggete - bagemaode metamorphic core complex developed adjacent to northwest of chagan sag , which evolved from late jurassic to cretaceous with three - layer construction style . the kinematics mechanism of metamorphic core complex and chagan sag is a simple shear model , chagan sag extended and faulted as the metamorphic core complex rised 在查干凹陷西北侧发育英格特?巴格毛德变质核杂岩带,可能具有三层结构模式,其形成与演化时代为晚侏罗世末?白垩纪;该变质核杂岩与查干凹陷的运动学机制为统一的简单剪切模式;在变质核杂岩隆升的同时,查干凹陷发生伸展断陷。 |
| 8. | Bachu arch is a large back - thrust uplift . tectonic evolution of its large boundary fault fracture have relation with oil / gas distribution involuntarily . its large boundary fault fracture is basement rift formed in late hercynian period and strongly actived in late himalayan period . oil / gas distribution of bachu - markit have relation with fault interspace distribution . so , this paper also discussed interspace distribution and movement stage of fault 巴楚隆起是一个大型背冲断隆,其边界大断裂的形成演化自然关系到本区的油气分布,隆起的边界大断裂多是海西晚期形成的基底断裂,后在喜山期强烈活动,兼具压扭走滑性质。 |
