鄂西北南化塘地区所进行的１∶５万区域地质填图表明，武当地块北缘滑脱构造经历了顺层伸展滑脱和收缩褶皱变形两个重要阶段。前者形成以３～４个主滑脱面为骨架的顶部由南向北的伸展滑脱系统，后者使这个结构系统褶皱复杂化，但仍继承早阶段由南向北的运动学规律。滑脱构造形成时代为晚海西—印支期，是与秦岭造山带主造山期时代一致的同碰撞伸展构造 The 1: 50000 regional geological mapping carried out in the South Huabutang area in northwestern Hubei Province shows that the northern part of the Wudang block has undergone two major stages of slippage and shrinkage in the extensional layer. The former forms a top-down slipping and slipping system with 3 to 4 main slippage as the skeleton, while the latter complicates this structural system folds, but still inherits the kinematic law from south to north in early stage. The slip-forming tectonic age is Late Hercynian-Indosinian, which is a co-strike extension structure consistent with the main orogenic age of the Qinling orogenic belt
