摘要: 黄龙场构造具有复杂的演化史,构造的形成演化经历了五个大的发展阶段,受到了川东高陡构造和大巴山构造带的影响;其中主要构造形成于喜马拉雅构造运动中期和晚期,喜马拉雅构造运动中期形成了黄龙场北东向的构造体系,喜马拉雅构造运动晚期是黄龙场主要构造的形成时期。该期形成的构造加强或改造了黄龙场早期的构造形态,最终使黄龙场构造定形为现今的构造体系。Abstract: Huangliongchang structure has complicated evolution history,its formation and evolution has undergone five major stages of development which is affected by east Sichuang steeply- folded structure and Dabashang structure,the main structure formed in the mid- and late of the Himalayan tectonic movement.The north-east of the tectonic system of Huanglongchang formed in the mid-Himalayan tectonic movement.The late Himalayan tectonic movement is the main stage that Huanglongchang structure formed.The north - west of the tectonic system that formed in late Himalayan tectonic movement strengthened or modified the earlier structure then formed the current tectonic system finally.
