Abstract: | The Kiselyovka-Manoma accretionary complex, formed at the end of the Early Cretaceous, is a part of the Early Cretaceous Khingan-Okhotsk active continental margin. It is located at the front of the Amur accretionary complex and is composed of Jurassic-Lower Cretaceous oceanic volcanic-siliceous deposits. The structural study of this complex in the Lower Amur region hSas made it possible to clarify its overall structure and to subdivide the folds with different morphologies and orientations into five types. The analyzed folding sequence is compared to the folds of the Amur accretionary complex. The fold kinematics indicates various senses of motions that do not reveal systematic kinematic patterns of stacking of the accreted tectonic slices. |
