| 摘 要： | 在武夷山中段西侧，即赣南于都—宁都一带，发育北北东向中生代逆冲构造系。该逆冲系由南东往北西逆冲，对其进行构造解析发现，是印支期和燕山期构造的叠加。其中印支期逆冲构造表现有构造窗和飞来峰等，显示缓倾角特征，在空间展布上呈叠瓦状，与晚古生代地层的褶皱相伴生，构成一种褶皱逆冲带型式的构造样式，这期构造被燕山期构造强烈破坏。

| Abstract: | On the western side of the middle segment of Wuyi Shan, where it is located at Yudu-Ningdu area in south of Jiangxi Province, the NNE-trending Mesozoic thrusting system is constituted. The thrusting system, verging towards northwest orientation, is superimposed structures developed during the Indosinian and Yanshanian movements. The Indosinian-stage structures are characterized by klippen and windows, show low-angle features and imbricated combination, as well as accompanied with syn-thrust folding, which then represent one of the fold-thrust structural style. The Indosinian-stage structures are intensely destroyed by the Yanshanian-stage struvtures. |
