Geomorphic Chrolondogy Based on the Climatic Changes for the Eastern Part of Chugoku Mts. during the Middle-late Pleistocene.

我们讨论了位于冈山县最北部的Chugoku山脉中心的Gorinbara高地的细池沼泽及其周围地形的沉积物。沉积物由砂质、粉质、粘土、沼泽土和泥质组成。采用三种取样器作为测试样品，对样品的粒度、密度、密度进行了分析。并对樟子树的樟子树和花粉进行了分析。在周边地区，由光滑表面、块流、崩坡、扇和岩崩等冰缘地貌组成。我们研究了这些地形，并讨论了沉积物与地形的关系。

We discussed on the deposits of the Hosoike moor and their surrounding land forms at the Gorinbara Highland in the center of the Chugoku mts, situated in Northern most Okayama Prefecture. The deposits composed of sandy-, silty-, clayey materials, bog soil and the tephras. We tack these materials by means of three kinds of samplers as testing samples and practiced on the grain size analysis, deusity, intoisity of those samples. also we anlayed on the tephras and the pollen.Of the surrounding area, there composed of the periglacial features, such as the smoothed surfaces, the Block stream, the colluvial slopes, the fans and the rock falls. We researched these topographies and discussed the relationship between the deposits and the land forms.
