Abstract:

黄土地层记录的磁学参数受控因素复杂,全球不同地区黄土磁化率的主要受控因子存在差别。文章在伊犁地区选取两个地层磁化率与成壤作用分别存在较明显正相关和负相关的典型黄土剖面,进行了系统磁性地层学研究。结果表明伊犁地区黄土地层中磁性矿物浓度较大,磁学性质主要受呈现准单畴状态磁铁矿控制,黄土沉积物中磁性矿物主要为原生矿物,后期改造作用弱,地层的磁学特征受物源影响明显。地层的成壤强度与地层中磁性矿物浓度无明显相关关系,与磁性矿物中细粒磁性矿物的含量呈正相关关系。本研究结果暗示伊犁地区黄土沉积物的磁化率增强模式既区别于典型的西伯利亚黄土"风速说"模型,也不同于中国黄土高原"成壤说"模型;当后期改造作用弱时,地层的磁学特征主要受物源影响;随着地层成壤作用的增强,对原生磁性矿物的改造作用逐渐增强,次生磁性矿物含量逐渐增加,磁化率变化规律趋近于"成壤说"模型。
