项目摘要
The proposed research concentrates on developing constraints on the fabric (the scale lengths and shapes of complex structures) in the inner core and lower mantle of the Earth from analysis and forward modeling of seismic waves interacting with these regions. Knowledge of the fabric of the inner core will help in understanding the process of solidification of the solid inner core from the liquid outer core, which is an energy source for maintaining the Earth's magnetic field. Knowledge of the fabric of the lower mantle of the Earth is important to models of mantle convection, deep plume formation, and chemical models of the mantle. Algorithms of forward modeling of the seismic wavefield developed in this research, which involve parallel clustered computing, are important to both resource exploration and to physical science and engineering applications requiring numerical modeling of phenomena described by systems of linear equations containing three-dimensionally varying physical properties.
拟议的研究集中于通过对地震波与这些区域相互作用的分析和正演模拟,发展对地球核心和下地幔的组构(复杂结构的规模、长度和形状)的限制。对内核组构的了解将有助于理解固体内核与液体外核的凝固过程,液体外核是维持地球磁场的能源。对地球下地幔的组构的了解对于地幔对流、深地柱形成和地幔化学模型的建立都很重要。本研究开发的地震波场正演模拟算法涉及并行集群计算,对于资源勘探和需要用包含三维变化物性的线性方程组描述的现象进行数值模拟的物理科学和工程应用都是重要的。
