摘要
本文介绍笔者在1：5万大水厂幅区调中，对元古界武当山岩群杨坪岩组褶皱特征及叠加现象的认识以及褶皱叠加样式的建立过程。杨坪岩组为一套浅变质的海相碎屑沉积岩类，岩石变形弱、变分层理（So）保留较好，褶皱现象易于识别且不同期次的褶皱特征明显，各自型式截然不同。笔者据J.G.兰姆赛提出的褶皱叠加型式，结合测区实际情况，建立起测区褶皱叠加样式。
Based on the results of the 1:50000 regional geological survey for Damuchang sheet, this paper deals with the suprimposed folds in Yangping rock formation of Wudang rock group distributed in the surveyed area. Yangping rock formation is composed of a series of epimetamorphic marine clastic sedimentary rocks with weak deformation and well preserved blastobedding structure(S。), in which the folds formed in different stages are easy to be distinguished with obvious features and completely different styles. Finally, the superimposed style of the folds in the surveyed area has been established according to the superimPOsed fold style proposed by J.G. Ramsy.
