采用X射线衍射分析方法,对辽宁地区第四纪松散沉积物发育古红土的黏土矿物特性进行了研究。结果表明:辽宁各种母质发育的古红土的黏土矿物中都含有伊利石、1.4nm过渡矿物和高岭石,朝阳地区古红土中含有少量的蒙脱石,大连地区则含有一定量蛭石;辽宁古红土黏土矿物的组成反映了不同于现代成土环境的占环境特征,现代的环境条件对占红土的某些性质也已产生影响。
This paper analysized the clay mineral characteristics of Paleosol derived from Quaternary aqueoglacial deposition through the X-ray diffraction method. The results show that, clay mineral composition of Paleosol all contain llite, 1.4 nm transi- tional minerals and Chlorite in Liaoning area, but Paleosol in Chaoyang also contains some Smectite and Paleosol in Dalian contains some Vermiculite. Clay mineral composition of Paleosol in Liaoning reflects the Paleoenvironmental characteristics which is very different from the modern time which showed that the modern environment has some impacts on some natures of Paleosol.
