新疆的黄土,中外学者曾经做过不同程度的研究。但是至今,几乎所有研究成果都未能涉及黄土的分层问题。近年来,新疆地质局第一水文地质工程地质大队对天山北麓和伊犁谷地黄土进行了研究,他们根据黄土的地质特征,所处的地貌部位和河流阶地的分析对比,古土壤的层次和颜色,所含化石和古人类遗址,同时进行了区域性层位对比,在此基础上明确将天山北麓的黄土划分为现代黄土、晚更新世黄土、中更新世黄土和早更新世黄土四层,并且将后三层黄土分别命名为“沙湾黄土”、“石场黄土”
Xinjiang loess, Chinese and foreign scholars have done different degrees of research. But so far, almost all the research results have failed to address the issue of loess stratification. In recent years, the First Hydrogeological and Engineering Geological Brigade of the Xinjiang Bureau of Geology has studied the northern foot of the Tianshan Mountains and the loess valley in the Yili Valley. Based on the analysis of the geological characteristics of the loess, the geomorphologic parts of the loess area and the terraces of rivers, the paleo-soil layers and colors , Including the fossils and ancient human sites, at the same time the regional comparison of the horizons, on the basis of the clear division of the northern foot of Tianshan loess into modern loess, late Pleistocene loess, the Middle Pleistocene loess and early Pleistocene loess four , And the latter three layers of loess were named as “Sandy Loess”, “Rocky Loess”
