| 中文摘要: |
| 阿尔泰造山带主要形成于晚泥盆世至早二叠世的主造山期，为一冲断—推覆—滑脱的造山作用、综合考虑多因素和多过程的非线性耦合与反馈作用对阿尔泰地区的造山与变形作用过程进行了数值模拟，模拟结果表明，该区造山变形作用是一个非线性动力学过程．在造山期的应力和变形演化是非线性的，并表现为应力的空间非均匀分布和进一步的变形强度的空间差异、变形岩石的变质作用是非线性的并导致变质岩石的空间非均匀分布．岩浆的侵入对造山变形有重要影响，同时也是导致区域非线性变形的重要地质过程和因素。 |
| 英文摘要: |
| The Altay orogenic belt,in Xinjiang,China was formed mainly during late Devonian to early Permian and was mainly a thrust-nappe-detachment orogenesis.The orogenesis and deformation in Altay area is simulated based on comprehensively considering the nonlinear coupling and feedback among many factors and processes.The results show that the orogenesis and deformation was a nonlinear dynamic process.The evolution of stress and deformation was a nonlinear which behaved as the nonuniform distribution of stress and different deforming intensity in space.The metamorphism of deformed rocks was a nonlinear which caused the nonuniform distribution of metamorphic rock in space.The intrusion of magma affected the orogenesis and deformation and it is an important geological process and factor leading nonlinear deformation. |
