extensional stress meaning in English
张应力
Examples
- According to most theories , the prevailing forces in the sicilian crust are similar to those in rift zones ? extensional stresses that cause thinning of the crust and upwelling of the underlying mantle
根据大多数的理论，西西里岛所在的地壳，主要遭受到的应力与张裂带类似：张力使地壳变薄、下方地函上涌。 - The meso - cenozoic evolution of bachu fault - uplift is closely related to its south and north subsiding foredeep . under the background of indian plate subducting under asia - europe plate , bachu forebulge was greatly affected by the development of southwest depression and awati depression . almost all of its structure reversed , and as a result of it , both of its south and north boundary migrated . according to its evolution history and its feature , the authors tentatively use both - side migration model to interpret the evolution of compound forebulge . since triassic , almost all the spheres above lithosphere synchronously became flexure . because transpressional stress field became increasingly strong , bachu forebulge continued uplifting and big faults formed . then , bachu uplift , as a whole , slipped upward along those big faults and showed migrating toward thrust zone in plane . in tectonic tranquility , the lithosphere bounded back and in consequence of it , bachu uplift slipped down and showed migration toward craton , at that moment negative inversion structures developed . while the forebulge migrated toward its south and north foredeep , it was very possible that locally extensional stress appeared in the forebulge
在印度板块向欧亚板块俯冲的大背景下，巴楚前缘断隆受西南坳陷和阿瓦提凹陷的影响，新生代时构造体制发生反转，边界向南北迁移。根据其发育过程特征，作者用复合前缘隆起两端迁移模式对复合前缘隆起独特的构造发育史进行了解释：即三叠纪以来岩石圈各圈层同步挠曲变形。随着挤压应力场的增大，巴楚隆起在挠曲基础上不断抬升，形成几条大型断裂带。 - The qiongzhong and danxian granites are belong to the kcg - type ( k - rich calc - alkaline ) granitoids according to the tectonic nomenclature by barbarin ( 1999 ) . these foliated kcg - type granites with original orientated structure are the results generated in a changing geodynamic orogenic environment with alternating compressional to extensional stress field . this suggests that hainan island has been a part of south china since latest permian , and been major in extrusion environment of the tethys tectonic system
根据barbarin ( 1999 )分类，琼中和儋县岩基花岗岩属于高k及含钾长石斑晶的钙碱性花岗岩，同时它们具有原生定向构造，是挤压?松弛?挤压的构造演化过程的产物，表明海南岛从二叠纪末期开始已经是华南大陆的一部分，主要受到了特提斯构造域的影响。
