1) detachment
[英][dɪ'tætʃmənt] [美][dɪ'tætʃmənt]
拆离
1.
In the process of intraplate convergence of continental lithosphere, parallel-layer detachments commonly occur during the subduction of continental crust, owing to the multi-layer and multi-interface characteristics of the subcontinental lithosphere.
与洋陆俯冲关系不同,在板内汇聚过程中,大陆岩石圈固有的多圈层、多界面结构的特点,使得地块的俯冲变形伴有多圈层顺层拆离解耦的行为,使变形结构复杂化。
2) basement decoupling
基底拆离
1.
The basement decoupling structure is the reaction in continent plate when the margin of continent plate is subducted,subdued,extruded and shortened.
基底拆离式构造是大陆板块边缘受到俯冲、消减、挤压和缩短作用时,在大陆板块内部的反应,即地壳内部受到水平挤压作用时,沿壳内“低速带”、“高导层”等软弱带产生多层次的拆离。
2.
The authors think that it is neither “thick-skinned structure” of an orogenic belt nor “thin-skinned structure” of sedimentary cover folds but belongs to “transitional basement decoupling structure”.
讨论了江南-雪峰山“隆起带”的性质问题,它既不是造山带的“厚皮构造”,也不属于沉积盖层褶皱的“薄皮构造”,而是“过渡型的基底拆离式”的构造。
3.
The basement decoupling structure is the reaction in the continent plate when the marginal of continent plate subducted、subdued、extruding and shorten.
基底拆离式构造是大陆板块边缘受到俯冲、消减、挤压和缩短作用时,在大陆板块内部的反应。
3) detachment fault
拆离断层
1.
The structural altered rock type gold deposit is hosted in steep dipping fracturing zones near the detachment fault.
构造蚀变岩型金矿产于拆离断层附近陡倾斜破碎带中 ,矿体定位明显受控于拆离断层。
2.
The gliding nappe consists of the detachment faults, the half graben faults and the metaphor'phic core complex.
甘肃安西县新金厂金矿床受区域性伸展运动形成的滑覆构造控制，由拆离断层、半地堑断层和变质核杂岩组成。
3.
The metamorphic cores consist of metamorphic complex rocks of the Lhagoi Kangri Group-complex and granites intruded therein;multi-layer,layering-parallel detachment faults are distributed around the metamorphic cores.
变质核由拉轨岗日岩群变质杂岩及侵入其中的花岗岩组成,围绕变质核发育多层顺层拆离断层,盖层主要为晚古生代和中生代浅变质岩石。
4) main detachment zone
主拆离带
1.
The main detachment zone system between metamorphic magmatic complex uplift and cover of the periphery of the mantle branch is good for ore-forming and ore-controlling structures.
幔枝构造是地幔热柱多级演化的第三级构造单元 ,其核部变质—岩浆杂岩隆起与外围盖层之间的主拆离带体系是很好的成矿控矿构造。
6) detachment structure
拆离构造
1.
Different shapes of detachment structure provides the transport channels and enriched spaces of ore-forming fluid.
成矿流体由地幔流体交代演化而来，成矿物质主要来自上地幔和下地壳，成矿时代为晚燕山期，不同形式的拆离构造为成矿流体提供了运移通道和富集空间，其成因类型为幔源中高温热液金矿床。
