本项目拟在中蒙边界以南和鄂尔多斯以北的阴山-燕山造山带地区布设20余套宽频带流动地震仪，与中国地震局地球物理研究所承担的国家科技部国际合作项目在蒙古国中南部地区布设的60套宽频带地震观测台阵、以及美国国家自然科学基金项目在蒙古国杭爱山脉地区布设的60套宽频带地震观测台阵，形成一个覆盖中亚造山带中南部地区的台阵观测系统，进行为期两年的天然地震观测，开展接收函数、SKS分裂、噪声和面波层析成像、以及体波层析成像研究，揭示研究区的深部地球物理结构特征，重点揭示研究区壳幔的垂向分层结构和横向分块结构，为中亚造山带形成与演化研究提供深部地球物理证据。

We plan to deploy about 20 passive broadband seismometers between the Sino-Mongolian border and the Yingshan-Yanshan Orogeny, such a seismic arry will join the Sino-Mogogolian Seismic array and Mongolian-US seismic arryary and constitute a larger passive seismic array to cover the southern and central region of Central Asian Orogeny Belt (CAOB), which will provide us a good opportunity to invert 3-D velocity structure of the crustal and mantle, derive deep deformation features of this region. We will gather 2 years passive seismic data to carry out study on receiving functions, SKS splitting, ambient seismic noise and surface wave tomography, and travel time tomography, exploring the vertical or lateral variations of deep structure with high resolution, proving the reliable geophysics evidence for the deformation and evolution of Central Asian orogen.
