对淮北变性土和长江下游变性型新成土的粘土矿物半定量研究表明,变性土胶粒和粘拉以蒙皂石占优势,粘料中蒙皂石占41.1％～56.5％,次为水化云母、高岭石。新成土胶拉以蒙皂石为多,粘粒则以水化云母为主,占43.6％～51.0％,次为高岭石,尚存蒙皂石及混层矿物。二地区土壤粘拉中含蛭石,但均未发现绿泥石。粉砂中矿物类型甚多,但几无蒙皂石。作者认为大量膨胀性粘土矿物存在,是土壤产生变性诊断特征的物质基础,因而是变性土鉴定主要依据之一。文中对上述土壤作了土属的系统分类和命名。
Quantitative semi-quantitative analysis of clayey minerals in the denatured soil in the north of Huaibei and the newly formed denuded soil in the lower reaches of the Yangtze River show that smectite and glucan are dominated by smectite, accounting for 41.1% -56.5% of smectite, Mica, kaolinite. The new geotextile with smectite as much clay is the main hydrated mica, accounting for 43.6% ~ 51.0%, followed by kaolinite, the remaining smectite and mixed layer minerals. Two regions of the soil stick to vermiculite, but did not find chlorite. There are many types of minerals in the silt, but few smectite. The authors believe that the presence of a large amount of expansive clay minerals is the material basis for the diagnostic character of soil degeneration and is therefore one of the major bases for the identification of denatured soils. The article made a systematic classification and naming of the above-mentioned soil.
