| 摘 要： | 通过粘粒矿物的定量分析,研究了我国东部花岗岩发育的红壤和黄壤的粘粒矿物组成。赤红壤、红壤和黄红壤的粘粒(<2μm)中高岭石含量分别为54%、42%和35%,这与该土壤的年均气温之间有明显的正相关(r=0.998,n=3),然而这三个土壤粘粒的风化淋溶系数与年均气温呈良好的负相关(r=1.000,n=3)。黄壤与红壤的粘粒矿物组成有明显的差异,黄壤中含有较多的三水铝石和2:1型粘土矿物,而高岭石较少;红壤中三水铝石很少,在安徽的黄红壤中虽有不少非晶质氧化铝,但未见有三水铝石存在。

| Abstract: | In this paper the clay mineral composition of red earths and yellow earths derived from granites in Guangdong, Jiangxi and Anhui Provinces were studied by using a quantttatwe analysis approach. It will he helpful for explaining mineralogical properties of red earths and yellow earths in different zones of the eastern China are also given in it. |
