摘要
闽北武夷山东部地区广泛发育早元古代麻源群,该变质岩系经历了多期次构造叠加改造,变质变形作用十分复杂。通过大量野外调研,查明其经历了5次褶皱变形。本文重点论述其不同时期变形特点及形成机制。
The early Proterozoic strata, Mayuan Group, are widely distributed over the eastern part of Wuyi Mountains in Northern Fujian, which underwent many stages of structural superimposed deformation. The survey and analysis show that the metamorphism and deformation in the strata are complex and there are totally five fold deformations for the strata. The paper focuses on the discussion of the deformation characteristics of early Proterozoic strata in different strata and of the formation mechanism.
