亚洲中东部岩浆岩网络状分布与塑性流动网络

亚洲中东部的岩浆岩分布具有明显的网络状特征，共轭相交的岩浆岩带构成了晚古生代、中生代和新生代不同的岩浆岩网络系统。岩浆岩网络受岩石圈下层塑性流动网络的控制，是塑性流动带剪切变形、摩擦热效应及带内介质弱化、轻化，以至促成地幔上隆和岩浆上涌的结果。根据“塑性流动－岩浆岩”网络，推测了不同地质时期大陆构造变形的驱动边界、驱动力方向和古构造应力场，并探讨了网络构造的演变等问题

NETLIKE DISTRIBUTION OF MAGMATITE AND PLASTIC FLOW NETWORKS IN CENTRAL AND EASTERN ASIA

The distribution of magmatite is characterized obviously by a netlike feature that magmatic belts intersect conjugately, forming a series of the late Paleozoic, Mesozoic and Cenozoic magmatic network systems. Magmatic networks are probably controlled by the plastic flow networks in the lower lithosphere, which result in upwelling of magma owing to shear deformation and friction thermal effect of plastic flow belts and the weakening and lightening of the intrabelt media.
