混合层粘土矿物是由两种或两种以上不同类型的粘土矿物晶层按不同比例、沿(001)基面平行地、相互重迭地组成规则或不规则结构的一种过渡型矿物。它是从一种粘土矿物向另一种粘土矿物转变的中间产物。自格鲁那(J.W.Gruner)于1934年在研究蛭石的过程中首次发现混合层矿物以来,相继有许多学者陆续报道了混合层矿物。经大量研究证明,混合层矿物分布极为广泛。在各种地质环境中,如风化壳、土壤、现代和古代的 Mixed-layer clay minerals are transitional minerals composed of two or more different types of clay mineral layers in different proportions, with regular or irregular structures overlapping each other in parallel along the (001) base. It is an intermediate from one clay mineral to another clay mineral. Since the first discovery of mixed-layer minerals by J. W. Gruner in 1934 in the study of vermiculite, many scholars successively reported mixed-layer minerals. After a large number of studies have shown that the mixed layer of minerals is extremely wide distribution. In a variety of geological environments, such as weathered shells, soil, modern and ancient
