造山期 meaning in English
mountain-building period
mp
orogenic epoch
orogenic phase
Examples
- Apo orogenic intrusion
造山期后侵入作用 - Yinggete - bagemaode metamorphic core complex belt with three - layer construction is put forward , which evolved from late jurassic to cretaceous . the extensional simple shear model of the chagan fault depression is established . the tectonic evolution and the dynamics character of chagan fault depression and its adjacent mesozoic - cenozoic basins are discussed : at the end of triassic continental orogeny increased crust thickness crust uplift and denudation were happened ; jurassic was a period of local partly extensional collapse of erogenic belt and cretaceous was a period of widely extensional collapse of postorogenic erogenic belt ; cenozoic was a period of the development of stable intracontinental depression with the character of long distant collision response and weaked compression flexure
讨论了查干凹陷及邻区中-新生代盆地构造演化及其地球动力学特征，三叠纪(印支期)为陆内造山作用与地壳增厚、隆升剥蚀阶段；侏罗纪(燕山早期)为造山后造山带的局部伸展垮塌阶段；白垩纪(燕山晚期)为造山期后大规模伸展垮塌作用与伸展盆地的发育阶段；新生代(喜山期)为远距离碰撞效应与弱挤压挠曲性质的稳定大陆内坳陷的发育阶段。 - Chagan sag is a secondary tectonic unit in chagandelesu depression , northeastern yingen - eji ' naqi basin , and the basement of the basin is a paleozoic fold belt of continental margin or island arc at the connection region of north china plate * tarim plate and kazakstan plate , with the character of erogenic belt . in working area and its adjacent area , the forming tectonic setting of indosinian intrusion was that orogenic belt pressed strongly , intracontinental subduction ; that of early yanshan movement epoch was the stress field transferred from compression to extension meanwhile the incrassate crust of orogenic zone turned to extensional collapse ; and that of early cretaceous volcanics was that the area structure extensional collapse further more during the post period of orogenic phase
查干凹陷属于银根?额济纳旗盆地东北端查干德勒苏坳陷内的一个次级构造单元，其盆地基底为古生代时期华北板块、哈萨克斯坦板块和塔里木板块交接部位形成的陆缘或岛弧褶皱带，具有古生代造山带的性质。研究区及邻区印支期侵入岩形成于造山带强烈挤压陆内俯冲的构造环境；燕山早期侵入岩形成于由挤压转向拉伸、造山带的增厚陆壳开始发生伸展垮塌的构造环境；早白垩世火山岩形成于造山期后进一步发生伸展垮塌的区域构造环境。 - Geological , geophysical and geochemical research indicate that ore deposits space distribution present belt in nw direction and strip in ne direction is controlled by the lengthwise structure and transversal structure . in the fold - thrust belt , those ore deposits formed in pre - intracontinental - orogenic stage , such as dingqinnong ag - cu polymetal ore deposit , have the character of one orebody beneath one , so it is optimistic to search new orebodys in deep
地质、地球物理、地球化学研究表明江达构造带矿床在空间上呈现北西成带、北东成条规律分布受纵向构造与横向构造的双重控制；在褶皱?冲断带，陆内造山期之前形成的矿床(如丁钦弄银铜多金属矿床) ，常出现矿体多层叠置、矿下有矿的现象，深部找矿前景乐观。 - And the generalized homothetic composite action of metallogenic subsystems mentioned above formed the multiple - composite metallogenic system of the jiangda tectonic belt . the typical ore deposits of jiangda tectonic belt , such as dingqinnong , jiaduoling , renda etc , are contact metasomatic type deposits formed intracontinental rifting stage , and the tectonic - magmatic - hydrotherm of intracontinental orogenic stage superposed and rebuilt some preexistent ore body . their space distribution is controlled by composite intrusive rock belt of ne direction
对丁钦弄、加多岭、仁达等典型矿床的研究表明，它们均为形成于陆内裂谷作用阶段的接触交代型矿床，陆内造山期的构造?岩浆?热液作用叠加改造了先成矿体，矿床空间分布受北东向复合侵入岩带控制。
