| 摘 要： | 本文对北亚热带地区七个白浆化土壤的原生矿物和次生矿物的特性进行了研究。重，轻矿物含量表明土壤继承了母质的特性，粘淀层与漂白层的母质沉积是间断的，前者风化强度大于后者。石英颗粒表现特征显示漂白层物来来源于黄土物质再堆积，粘土矿物以水云母为主，其结晶度较差，氧化铁类型以针铁矿和赤铁矿为主，也有非晶质氧化铁和硅酸盐中的Ｆｅ＾２＋，其形成条件与现代化成土条件一致。

| Abstract: | This paper deals with the primary and secondary mineralogical properties of seven pedons of albic soils from the northern subtropical region of China. The contents of heavy and light minerals show that the soils inherit the parent material properties, the parent material between albic E horizon and argillic horizons are lithologically uncountinous, and the former horizons are weathered strongly than latter ones. The surface of the arenaceous quartz shows albic E horizons result from the loess reaccumulation. Hydromica dominates the clay fraction of albic soils, the kaolinite formation and clay mineral crystallinity show the desilicification and depotassication, the clay minerals can collapse to some extent. The dominant iron oxides are hematite and geothite, these iron oxides are proved to have formed under the conditions consistent with present ones. |
