摘要
武当山推覆体中段存在六期叠加褶皱(B_1～B_6),其中B_1,B_2,B_3为推覆期前褶皱,B_4,B_5为推覆期褶皱,B_6为推覆期后褶皱。以六期叠加褶皱为基础,再结合区内存在的反转盆地等拉张性构造,将区内的构造演化序列划分为七个变形幕。
During the study of geological work on the middle segment of Wudang Mountain Nappes the author of this paper discovered six stages of superimposed folds (B_1~B_6). Among them, B_1, B_2, B_3 are folded before the napping, B_4, B_5 are folded during the napping, B_6 is folded after the napping. Based on this six stages of superimposed folds and acompanied with the apperance of extensional structures, e. g. inverse basin, the tectonic evolutionary sequence of this region can be divided into seven deformation episodes.
