| 摘 要： | 对陕西省11个主要土类50个样本的粘粒进行研究结果表明,发育在黄土母质上的黄绵土、黑垆土、(土娄)土和褐土,粘粒矿物以水云母为主,并含有一定量的绿泥石、高岭石和少量蒙脱石;在红棕色粘黄土母质上发育的黄褐土和水稻土,粘粒矿物仍以水云母为主,但含有较多量的高岭石和蒙脱石;山地黄棕壤、山地棕壤、山地暗棕壤、森林草甸土和亚高山草甸土粘粒普遍富含水云母,蛭石和绿泥石,其主要矿物组合有明显的不同。

| Abstract: | Mineralogical composition of the clay fraction separated from fifty soil samples,representing eleven predominant soil types in Shaanxi province,was investigated,The results showed that the loessial soil,orthoheilu soil,lou soil and cinnamon soil developed on loess contain dominantly hydromicas with certain chlorite,kaolinite and a small quantity of montmorillonite,While the yellow cinnamon soil and paddy soil developed on red-brown clay loess are chiefly of hydromicas with more kaolinite and montmorillonite,Although the mountain yellow brawn earth,mountain brown earth,mountain dark-brown earth,forest and sub alpine meadow soils are rich in hydromicas,vermiculite and chlorite,the mineral proportions are difference signficantly. |
