中国东部第四纪冰期之我见——庐山更新世冰川发育“有限性”初探

THE QUATERNARY ICE AGE IN EASTERN CHINA—A PRELIMINARY STUDY OF THE "LIMITATION" OF THE PLEISTOCENE GLACIATION IN MOUNT LUSHAN

中国东部(含庐山)第四纪冰期之争,表现在地貌、沉积与冰川发生条件三个方面。笔者认为:庐山冰川仅发生在早更新世,并建立了金锭山冰期。中晚更新世没有冰川发生,前人提及的某些冰川作用证据需要重新认识。庐山晚新生代地层分为18个层组,含11级阶地,只有一个可靠的冰碛层,其他为非冰碛层或似冰碛层。

The disputes about the Quaternary Ice Age in eastern China (including Mount Lushan) involve three aspects, i. e. topography, sedimentation and conditions of glaciation. The author holds that the glaciation in Mount Lushan took place in the Early Pleistocene. According to this view, the Jindinshan Ice Age has been set up. No glaciation happened in the middle Late Pleistocene. The evidence of glaciation put forwards by predecessors requires reconsideration. Late Cenozoic sediments in Mount Lushan may be divided into 18 formations and 11 levels of terraces, including one drift sheet and two dubious drift sheets; while others are non-glacial deposits.
