摘要: 黑龙江省龙江县朱家坎附近(大兴安岭东坡)的白土山剖面,曾是东北下更新统地层的模式剖面,早在五十年代初就受到地质、地理工作者的重视。1959年全国地层委员会将白土山的第四纪地层命名为白土山组,其时代为早更新世,其底界为第四纪的下限。此后,白土山组被广泛地引用和对比。白土山组地层在松嫩平原和三江平原为第四纪孔隙水主要含水层之一,所以,研究它不仅具有重大的理论意义,而且具有重要的实践意义。

Abstract: The Bailushan profile near the Zhujiakan towns, Longjiang county,Hei-longjiang province, was a model profile of Lower pleistocene strata in the Northeast China. The profile was named "The Baitushan Formation" in 1959. Afterwards "The Baitushan Ice Age"has been built according to the viewpoint of glacial and fluvial deposit of this strata.In fact, the Baitushan formation strata have characteristics of alluvial and proluvial facies,and constitute a series of fossil alluvial-proluvial fan landforms in the east foot of the Daxinganling mountain range. The components of clay mineral are mainly halloysite, and contain montmorillonite. Spore-pollen assemblage is mainly characterized by xerophyte wormwood, lamb’squarters and so on, thus the paleo-vegetation belongs to grassland landscape. Above mentioned facts indicate that the Baitushan formation strata is sediment of alluvial and proluvial facies under warm and dry climatic environments, but not glacial and fluvioglacial deposit. Therefore, there is not so called "The Baitushan Ice Age".
