米仓山-龙门山-康滇前震旦纪岛弧系统的确立该带在前震旦纪晋宁期是一个海沟岛弧系统,前人已在该带的部分区段,从不同的角度提出过这个问题.这些研究中,前震旦纪古岛弧的证据还不配套,有的是分段研究的,未对整个带作专门论述.笔者认为有必要根据区域地质和地球物理资料,进一步确立该带作为古板块活动边缘的可靠性,并概要地阐述该带前震旦纪板块运动的模式.
The establishment of the Pre-Sinian island arc system in the Micangshan-Longmenshan-Kangdian region. This zone was a trench island arc system in the Pre-Sinian Jinning Period. The predecessors had already raised this issue from different angles in some sections of the belt In these studies, the evidence of Pre-Sinian paleoclassical arc is not well-matched and some of them are subdivided into studies without specific discussion of the whole belt.I think it is necessary to further establish the belt as an ancient plate according to regional geological and geophysical data The reliability of the active margin, and a summary of the mode of movement of the Pre-Sinian plate.
