Based on relatively comprehensive survey, mapping and statistic analysis, the authors have reached the conclusion that the cleavable zone is distributed in the discontinuous banded form, with its scale in relation to the river slope scale, so there exist large-sized zones along the Jinsha River and the Lancang River, and that the cleavable zone is in connection with the local micro-landform. In addition, the “cleavage” in the zone is characterized by steep dip angle and uneven interval, with its strike usually paralleled to the local river orientation. The zone was generated by the interaction between the endokinetic process and the exogenous process. This means that the cleavable zone could be generated by the endokinetic process, and that on the basis of the endokinetic process, the cleavable zone along rivers could also be formed by the exogenous process.
