| 摘 要： | 流褶层与韧变带是地壳拉伸变形，顺层固态流变作用下的产物。流褶层是以原始层理为变形面或再经递进变形的褶皱变形岩层或岩石共生组合层位。韧变带具明显的层控性，受岩石成分和应变程度控制，不同环境和不同成分岩石的韧变带具有相异的组合型式和变形机制，井具有一定的递变规律。流褶层和韧变带可分属不同层位，但流褶层可实现向韧变带的转化。

| Abstract: | Rheological fold layers and ductile-metamorphic belts are products of stretching defor-mation in the crust under the effect of bedding solid-rheological behaviours. The former isfolded strata or rock association strata evoluted from original bedding or their progressive de-formation;the latter has obvious stratabound characteristics with a regular progressive pat-tern,and their assemblage styles and deformation mechanism are controlled by rock composi-tion and degree of strain. Rheological fold layers and ductile- metamorphic belts probably oc-curred in different stratohorizon and it is also possible for the former to transformed into thelatter. |
