| 摘 要： | 对大量磁测和化学分析资料的统计分析结果表明,所有红壤的磁性均与弱晶质氧化铁矿物的含量有密切的关系,而强磁性矿物Fe_3O_4,r-Fe_2O_3则在磁性较强的红壤中有明显的作用.据此,提出了各种氧化铁矿物在数量上的积累和结晶程度的变化,是红壤磁性演变的基本原因的观点.

| Abstract: | Data correlation analysis shows that general weak crystal iron oxide minerals play an important role in soil magnetism of all kinds of red soils, and the effect of Fe3O4 r-Fe2O3 must be included only for the relatively strong magnetic red soils. The basic result of this article is that the change of red soil magnetism is related with the content and state of iron oxide minerals. |
