摘要
通过 1∶2 5万中甸县幅、贡山县幅区调实践 ,初步认为 :造山带及变质岩区填图 ,可采用“构造岩片多重分解综合复原法”。研究途径和技术路线为 :以当代先进的构造变形、变质作用理论为指导 ,从划分构造岩片入手 ,对构造岩片进行多重分解。在分别查明各构造岩片的物质组成、生成时期、形成环境及原始位态的基础上 ,进行构造岩片的逐级组合与综合复原 ,揭示造山带的形成机制及大地构造演化历程。
In the 1∶250000 regional geological mapping of Zhongdian Gongshanregion,the multiple decomposition and comprehensive restoration method has been effectively applied to the orogenic belt and metamorphic region.This mapping approach is as follows.First,to divide and multiplely decompose the tectonic rock flake are carried out according to the current advanced structural deformation and metamorphism theory.Then,on the basis of a study on their constituent,period an environment of formation and original state,the tectonic rock flakes are combined in order and comprehensively restored in order to know the formation mechanism and tectonic evolution of the orogenic belt.
