虽然普遍认为混杂堆积来自于俯冲带,但与那种具有特殊混杂外貌的混杂岩形成机制大不相同。对这个问题的争论,集中在刮落或底侵作用发生过程中沿内海沟斜坡的重力下滑作用和沿冲断裂产生剪切作用的效果上。尽管出露在大陆上的某些混杂沉积,虽适合于一种滑 Although it is generally accepted that the melanges are derived from the subduction zone, it is quite different from the formation mechanism of that melange that has a particular hybrid appearance. The debate on this issue has focused on the effects of gravitational sliding along the inner trench along the slope of the inner trench and the shearing effect of the thrust along the bluff. Although some of the mixed sediments exposed on the mainland, although suitable for a slippery
