中文拼音 [bēixíngnáoqū]
背形撓曲
英文
antiformal flexure-
Due to the multi - period tectonic movement and evolution of mechanical mechanism, syndeposition structures occur extensively in jiyang sag, the base of the sag subsided alternatively during the fault depression, which resulted in sinking of top bending and complicated block structure accordingly, reconstructed the syndeposition intensively, and produced the special structural landscape in combination with all levels of faults and sedimentary formations within it
摘要濟陽坳陷由於受到多期構造運動的影響，在前第三系古地形高點背景上廣泛發育同沉積背斜構造，然而由於坳陷在斷陷期基底滾動式沉降，造成撓曲頂部的塌陷，形成復雜的塊斷結構，使本區同沉積構造發生強烈改造，往往與各次級斷層或沉積地層相復合，表現出獨特的構造景觀。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
在印度板塊向歐亞板塊俯沖的大背景下，巴楚前緣斷隆受西南坳陷和阿瓦提凹陷的影響，新生代時構造體制發生反轉，邊界向南北遷移。根據其發育過程特徵，作者用復合前緣隆起兩端遷移模式對復合前緣隆起獨特的構造發育史進行了解釋：即三疊紀以來巖石圈各圈層同步撓曲變形。隨著擠壓應力場的增大，巴楚隆起在撓曲基礎上不斷抬升，形成幾條大型斷裂帶。
