fold basement meaning in English
褶皱基底
Examples
- The tectonism in this area can be divided into three phases , that is the folded basement formation and stable ancient land in pre - mesozoic , ancient land cracking phase in mesozoic , the faulted activity and subsidence phase in cenozoic
本区构造变动划分为三个大的阶段，即：前中生代褶皱基底的形成和稳定古陆发育阶段、中生代古陆裂解阶段、新生代块断活动及整体沉降阶段。 - This thesis studies each structural layer ' s feature : ( 1 ) structural layer of basement : it is a paleozoic folded basement , whose tectonic deformation and magma intrusion is fiercely , and it is affected by the early hercynian tectonic movement and related to the underthrust and closure ( c1 ) of zhungaer ocean basin and the areal pressing of continents ( c2 - 3 ) ; ( 2 ) structural layer of permian : due to the regional extending and fault depression role in mid - hercynian , it occurred to the combinations of structure and magma in santanghu basin and it ' s periphery area , such as a - granite ' s stock , batholiths and diabase ' s dike . there are many fault depressions possible
按照不同构造层，研究了各构造层的构造特征：基底构造层：受早海西期构造作用的影响，与准噶尔洋盆俯冲闭合、而后陆-陆碰撞的区域挤压构造作用有关，为一构造变形和岩浆侵入活动强烈的古生代褶皱基底。二叠系构造层：受中海西区域性伸展断陷作用的影响，盆地及其周缘地区发育与伸展构造有关的构造-岩浆组合，如呈岩株、岩基状侵位的a型花岗岩以及呈岩墙状侵位的辉绿岩等。 - More and more evidences suggest that the fold basement of yangtze block is an integral part of the grenville - aged orogen . the yanbian group , which resulted from post - grenville orogen , outcrops in the panzhihua area , sichuan province . hence , the studies on the geological features and geotectonic implications of the yanbian group can provide some clues to refine the position of yangtze block in rodinia
扬子陆块在rodinia中的位置是近几年来的热点问题，愈来愈多的证据显示它的褶皱基底是grenville期造山带的重要组成部分，盐边群是扬子陆块褶皱基底的组成部分，研究它的地质特征和大地构造属性，可以为研究扬子陆块在rodinia中的位置提供重要的地质线索。 - The basement of the basin is consist of precambrian crystal basement and paleozoic folding basement , while the cover has undergone the evolution of intra - continental rife in permian , down warped basin in triassic - cretaceous period and inter - mountains basin in tertiary . the main sediments are huge - thick volcanic rock , shallow intrusive rock and tuff in early permian , dark mudstone , marl and muddy dolostone in lucaogou formation in middle permian , huge thick volcanic rock , intruder in tiaohu formation in middle permian , miscellaneous sandy gravel , sandstone and gray mudstone in triassic ( the red is under the gray , and huge - thick dark gray , gray sandy gravel , sandstone , mudstone with coal layer in jurassic
盆地基底由前寒武纪结晶基底和古生代褶皱基底组成，盆地盖层则经历了二叠纪的裂谷盆地、三叠纪?白垩纪的坳陷盆地和第三纪后的山间盆地的演化过程。盆地主要沉积了下二叠统巨厚火山岩、浅成侵入岩和凝灰岩；中二叠统芦草沟组的暗色泥岩、泥灰岩、白云质岩石以及条湖组的巨厚层火山岩、侵入岩；三叠系杂色砂砾岩、砂岩及灰色泥岩(下红上灰) ；以及侏罗纪厚层深灰、灰色砂砾岩、砂岩、泥岩夹煤层。
