摘要
庐山东约300 km的浙西千里岗山,海拔1 523 m,高于庐山1 474 m,山顶出露岩层为夹粉砂质泥岩的岩屑石英砂岩的志留系上统唐家坞组,岩性软弱。以赣北庐山为代表的中国东部第四纪冰川问题,是我国地质、地理学界争议最大、认识最分歧的重大问题,"庐山第四纪冰川"认识分歧的重要原因是山地侵蚀地貌形态和相应堆积物的多解性。依据地貌垂直地带性理论,软弱岩层的分布高程,不可能超过冰川地貌带上限,也就是说,没有达到冰川地貌带的高度。为此,通过"跳出庐山看庐山",判别庐山第四纪冰川的有无。认为,千里岗山与包括庐山在内的邻近地区的同高程山地的高度无第四纪冰川发育。
Quaternary glaciation in the low mountain-hill regions of East China, represented by Lushan Mountain North Jiangxi, is one of the most controversy and divergent issues in geology and geography in China, because multiple explanations of the erosive landforms and the relative deposits. The issue on the quaternary glaciation in the Lushan Mountain is discriminated by using a way of ＂Out of Mount Lu to see Mount Lu＂. Qianligang Mountain in West Zhejiang, 300 km east to the Lusha Mountain, has an elevation of 1 523 m, which is higher than 1 474 m of the later. Clastic rocks of the Tangjiawu Group of Upper Silurian, such as sandstone, sihstone and mudstones are bution elevation of those types don＇t reach to the elevation of lar or less elevations including to vertical geomorphology zone theory, the highest distil- of soft rocks is limited to the upper elevation of the perglacial zone, in other words, the glacial zone. Therefore, Qianligang Mountain and the other mountains with simi- Lushan Mountain have no glaciations.
