铝铁

Soils dominated by 2:1 clays(montmorillonite, vermiculite, illite), more frequently found in temperate zones, but also present in tropical and subtropical areas; behave different from the typical tropical red soils (Ultisols and Oxisols dominated by Fe and Al oxides and kaolinite) and from the soils developed from volcanic ash (Andisols dominated by allophane, imogolite, and humus-Al complexes) that are widely spread over the world.

我们常在温带地区发现的2：1型粘土矿物为主的土壤，也出现在热带和亚热带地区。这些土壤不同于世界范围内广泛分布的典型的热带红壤(以铁铝氧化物和高岭石为优势粘土矿物的老成土和氧化土)，也不同于由火山灰（以水铝萤石、伊利缟石和腐殖质-Al复合体为优势粘土矿物的火山灰土）发育的土壤。
