支承壓力帶 的英文怎麼說
中文拼音 [zhīchéngyālìdài]
支承壓力帶
英文
abutment area-
According to the analysis of the structure deformation variant direction the structure superposition during late period, and the tectonic stress field and deformation variant field, the cover extended nearly sn direction in early stage ( d - c ), maybe changed the direction in pernian ( especial the late permian ), and developed some new half - graben along sn direction except the succession activity at great fault zone. the direction of compression deformation variant, however, was nearly sn direction in indo - chinese epoch, ne - sw direction in early yanshan movement epoch, nne - ssw direction in late yanshan movement epoch, and transformed from ew to sn direction in himalayan movement epoch
根據不同構造層中變形方向及後期構造疊加的分析,對本區的構造應力場及變形場進行了探討,本區蓋層早期階段( d - c )為近南北向的伸展拉張,二疊紀(特別是晚二疊世)的伸展方向可能發生了改變,除在各斷裂帶繼承性活動外,沿南北方向又新生了一些半地塹。而在擠壓變形時,印支期主要為近南北向擠壓,燕山早期為nw - se向擠壓,燕山晚期為nne - ssw向擠壓,而喜山運動可能經歷了從ew向向sn向方向擠壓的轉變。Tectonic analysis controlling gold mine mineralization in taihua group suggest that ductile fractures chang into brittle - ductile ones going with upliftling of xiaoqinling area after in - china orogeny. brittle fractures form on the basis of brittle - ductile ones that develop and inherit the characteristic of the latter stress field. folds and faults analysis in taihua group and its bilateral reveal that yanshanian tectonic evolution of xiaoqinling area undergo at least three phases of deformation
太華群內金礦成礦構造分析表明,印支期碰撞造山後小秦嶺擠壓抬升,控礦韌性剪切帶向脆韌性轉化( 207 148ma ) ,在脆韌性剪切帶基礎上疊加改造形成容礦斷裂,脆性斷裂的發育繼承了韌脆性剪切帶發育時的應力場特徵。
