Pretreatment methods and their influences on grain-size measurement of aeolian "red clay" in North China 前处理步骤与方法对风成红粘土粒度测量的影响
Aeolian red clay and loess; 风尘红黏土-黄土;
It is considered that the paleo-weathering crust in the mountainous regions in Central Asia is possibly an important source of aeolian deposits, especially is one of the important sources of Cenozoic red clay. 认为亚洲中部山地古风化壳可能是中国北方早期风尘沉积,尤其是第三纪红粘土的重要物源之一;
Aeolian red clay and loess deposited in northern China since late Neogene is an ideal palaeoclimate recorder. 中国北方黄土高原地区堆积了晚新近纪以来厚达上百米的风成红粘土-黄土序列,是古环境、古气候信息的良好载体。
