本项目拟以虎林-额尔古纳宽频带地震剖面观测资料为基础，以兴蒙造山带诺敏河-奎勒河火山群为中心，用30余套宽频带地震仪布设一个二维地震台阵，跨越大兴安岭重力梯度带，进行为期两年的地震观测，并结合周边的固定地震台站资料，开展接收函数和体波层析成像研究，获取诺敏河-奎勒河火山及其邻区的岩石圈底界面埋深以及上地幔三维速度结构，为钾质火山岩的成因研究提供深部地球物理证据。

Based on the passive broadband seismic array data along the Hulin-Argun profile, we schedule to deploy about 30 broadband seismometers to focus on the Nuominhe-Kuilehe Volcano and pass through the Daxinganling Gravity Gradient Zone, and plan to carry out 2-year passive seismic observation to obtain continuous seismic data to investigate the deep structure around the Nuominhe-Kuilehe Volcano. We will conduct study on receive function and body wave travel time tomography, to reveal the depth of lithosphere- asthenosphere boundary and 3D velocity structure of the upper mantle, and to provide the reliable geophysics evidence for the origin of the potassic Nuominhe-Kuilehe Volcano.
