计算表明,俯冲带深部主要矿物相的流动强度差异很大。俯冲带矿物流动强度的差异和构造环境复杂性预示着俯冲带深部物质变形是非均匀的,这种非均匀性是控制俯冲带内许多地质、尤其是动力学过程的重要因素之一。通过分析俯冲带构造物理背景和俯冲带深部矿物流变性质变化,研究了俯冲带深部非均匀变形的特征,在此基础之上讨论了板舌变形的几何形态、俯冲带火山活动性、中、深源地震活动性、板舌下插深度和消减过程与俯冲带非均匀变形的相变性。
Calculations show that the flow intensity of the major mineral phases in the deep subduction zone varies greatly. The differences in the flow intensity of the subduction zones and the complexity of the tectonic environment indicate that the deformation of the deep subduction zone is nonuniform. This nonuniformity is one of the important factors that control the many geological, especially dynamic processes in the subduction zone. Based on the analysis of the physical background of subduction zone structure and the change of mineral properties in the deep subduction zone, the characteristics of the deep non-uniform deformation of the subduction zone are studied. Based on the above analysis, the deformation of plate tongues, the volcanic activity of subduction zone, Seismicity of deep source, depth of plunge insertion and phase transformation of subduction zone and nonuniform deformation of subduction zone.
