与大褶皱同时形成的次一级中、小褶皱称为从属褶皱(subordinte folds)。从属褶皱的研究对恢复大褶皱的产状和形成机制,以及指导找矿勘探均有一定的理论和实际意义。因此,国内外地质学家都比较重视对它的观察和研究。T.N.戴尔(Dale)于1896年提出从属褶皱八十余年来一直存在两种不同的观点:一种认为同时形成的大小褶皱在 Subfamilies, small folds, formed simultaneously with large folds are called subordinate folds. The study of subordinate folds has certain theoretical and practical significance for the recovery of the occurrence and formation mechanism of large folds and for the exploration of prospecting and exploration. Therefore, geologists at home and abroad pay more attention to its observation and research. T.N. Dale Subordinate Creases in 1896 There have been two different perspectives for more than eight decades: one is that size folds, which are thought to form simultaneously
