摘要
本文在高梯度磁选法分离红土中氧化铁矿物基础上，运用穆斯堡尔谱学方法对红土中氧化铁矿物进行了系统研究，并建立起红土中氧化铁矿物分析流程和研究方法体系。研究表明，红土中氧化铁矿物主要有针铁矿、赤铁矿和磁赤铁矿。氧化铁矿物沿红土剖面分布的规律性，记录了成土环境和古气候的周期性变化特征，具有重要的环境指示意义。
On basis of high gradient magnetic separation of iron oxide minerals from the laterite developed on carbonate in Guizhou,studies have been made of the iron xoide minerals bymeans of the Mossbauer spectroscopy. These studies show that goethite, hematite andmaghaemite are the main iron oxide minerals in the laterite. The regular variation of the ironoxide minerals associations along the laterite profiles records the changing of the pedogenicenvironment and is'of great environmental significance.
