摘要
综合考虑松辽分水岭东段地区白土山组的地层分布、沉积特征、地貌部位及第四纪以来松辽分水岭的演化过程、松辽水系的变迁，认为其为河流冲积物，形成时代为早更新世早期。
This paper has studied the strata of the Baitushan Formation distributed in the eastern area of the Songliao Divide. According to (1) its distribution, sedimentary characters, geomorphic place, (2) the evolution of the Songliao Divide in the Quaternary Period and (3) the evolution of the Songliao drainage system, we think the genesis of the strata is alluvial sediments, though it used to be regarded as glairo--fluvial sediments, its sedimentary age is the early time of the early Pleistocene (Q1 ), though it used to be regarded as whole Q1.
