增生楔

BSR分布于增生楔部位，受区域构造沉积条件控制明显。

The BSRs are distributed over the accretionary wedge , clearly controlled by tectonic and sedimentation conditions .

北祁连加里东期俯冲-增生楔结构及动力学

Framework of North Qilian Caledonian subduction ? Accretionary wedge and its deformation dynamics

自中中新世以来，南海洋壳开始沿着马尼拉海沟向菲律宾海微板块俯冲，形成增生楔中洋内俯冲增生部分；

Since the middle Miocene , the South China Sea had subducted beneath the Philippine Sea Plate along the Manila Trench , and the subduction prism came into being .

通过对南海973航次在该区域的多道地震剖面的解释，对该增生楔进行了构造单元的划分，并分析了变形特征。

The structural geometry , kinematics and density structure of the Taiwan accretionary prism were studied based on the interpretation of a multi-channel seismic profile obtained during a " 973 " survey .

台湾增生楔位于欧亚板块、菲律宾海微板块和南海的结合部位，是现代弧陆碰撞研究的理想场所。

Taiwan accretionary prism lies in the conjunction area of the Eurasian Plate , the Philippine Sea Plate and the South China Sea , and is characterized by the young age of the arc-continent collision .

经过初步的侵位机制分析，可知这套火山岩经历了海沟增生楔、弧前盆地基底，并接受了盐边群碎屑岩的沉积。

The primitive study on the emplacement mechanism suggests that the volcanic rocks had underwent the stages of the trench accretion and the basement of forearc basin , which received the elastics of the Yanbian Group .

在增生楔部位，地层深部的流体（热液及甲烷气体等），在挤压构造应力及浮力的作用下，沿断层及地层孔隙运移至海底浅层，形成水合物。

Drived by tectonic compressional stress and buoyancy force , deep fluid ( warm liquid , methane and so on ) migrates up along faults and porosity in the sediments , and gas hydrate is formed in the shallow sediments of accretionary wedge .

俯冲&增生型造山带增生楔流体研究进展

Advances on fluid of accretionary wedge in the orogene of subduction - accretion

增生型造山带的基本特征是：①具有很宽的增生楔，增生楔中的复理石基质向着海沟后退方向时代逐渐变新；

The basic characteristics of this type of orogen are : ( 1 ) there is a very wide accretionary wedge , in which the thrust sheets of flysch matrix are younger towards the trench ;
