| 摘 要： | 重新厘定的武当山岩群（包括三个岩组）,经历了三期构造变形。前印支期以近南北向水平分层韧性剪切及顺层掩卧褶皱为特征;印支主期为北西向倒转同斜褶皱及伴随的推覆型或走滑型韧性剪切带;晚印支期以北西西向—近东西向开阔褶皱及脆韧性推覆构造为特征。由此铸造了武当山岩群现今北西—近东西向复式倒转背向斜间到（局部似“穹盆”）及脆韧性剪切带分割拼贴的构造格局。

| Abstract: | Re-determined Wudangshan group complex consisting of three rock associationshas undergone three ages of structural deformatinn characterized by nearly S-N strike horizontalslicing ductile shear zone and bedding hidden fold in early Indosinian, nearly N-W strike overturned-isoclinal fold with napping or strike-slip ductile shear zone in major Indosinian andNWW to nearly EW strike broad fold and brittle-ductile nappe structures in late Indosinianwhich form a present tectonic framework of Wudangshan group complex that is NW tO nearly EWstrike multiple overturned anticline alternating with syncline partly like "domal basin", dismembered or matched by brittle-ductile shear zone. |
