摘 要: | 对杭州附近由第四纪红土、泥岩、石灰岩和花岗岩发育的红壤中磁性矿物进行了研究 .由X -衍射和矿物磁测技术证明四种红壤中的磁性矿物是磁赤铁矿 (γ -Fe2 O3) ,它是红壤磁性的主要贡献者 ,且磁赤铁矿以稳定单畴和超顺磁性颗粒态存在

Separation and diagnosis of magnetic minerals in red earth |
| |
Abstract: | The X-ray diffraction patterns of soils and iron oxides extracted with magnetic separation suggested that magnetic minerals could be extracted effectively from red earth for further studies. Mineral magnetic measurements and X-ray diffraction patterns of soils developed on Quaternary red clay, mudstone, limestone, and granite indicated that the soil magnetism is attributed mainly to maghemite (γFe 2O 3). |

Keywords: | Red earth X-ray diffraction Mineral magnetic measurement Maghemite |
