摘要
黄土高原早期环境 ,应该同其周边环境大体相似 ,也存在冰期问题 :三套“砂质黄土”是冰期遗物的唯一表象 ,这是因为冰体夹在黄土层中间 ,基本丧失了冰川形成条件 ,故虽有冰期而无冰川 ,自然也就没有山岳冰川所形成的各类遗物 。
This paper suggests that there exists the glacial stage in the Loess Plateau because its early environment may be correspond to its around regional environment.The “Sandy Loess”is only remaining during glacial stage in the Loess Plateau.The glacial bodies between two Loess layers essentially loosed the conditions of glacial formation.Because of the above the glacial stage must exist when glacier and its traces do not exist in the Loess Plateau.
