We obtain P-and S-wave velocity tomography and V p/V S perturbation images at different depths beneath the Changbaishan Tianchi volcanic region by three-dimensional velocity structure inversion.
利用三维地震透射观测系统所获得的莫霍界面反射波对长白山天池火山区下方上地壳的三维速度细结构进行了反演计算 ,得到了研究区下方地壳内不同深度的P、S波速度层析成像和VP VS 扰动分布图像 ,结果表明 ,天池火山区及其周边速度结构所呈现出的非均匀性变化与该区的地质构造和岩浆系统的存在有着密切的关系 ,异常变化比较明显的低P波速度异常体分布和高VP VS 扰动体意味这些介质体处在“软化高温”的状态 ,这与该地区广泛分布的地热异常和低Q值结构的研究结果是一致的 。
