【摘要】 民和黄土处于黄土高原与青藏高原东北部的交合处 ,对气候反映较为敏感 ,有比其它黄土更高的气候分辨率 .将民和黄土各粒径组分含量变化与磁化率曲线对比 ,并利用相关分析方法发现 :青藏高原东北缘黄土 >3 0 μm的粗颗粒组分可以作为较敏感的东亚冬季风代用指标更多还原

【Abstract】 Comparing the different grain size fraction from the Minhe loess with the magnetic susceptilibility curve,and using the methods of relative analysis,we find that >30μm size fraction from the Loess in the northeast of Qinghai-Tibet Platean can be regarded as an indication of the changing strength of the East Asian winter monsoon.更多还原
