五香坡粘土是由石英钠长斑岩风化而成的一种粘土。该粘土主要由高岭石、蒙脱石和伊利石组成,而且伴生了少量的混合层粘土矿物。混合层粘土矿物通过用乙二醇处理与加热至520℃(1.5h)后的X射线衍射鉴定,它们是伊利石-蒙脱石规则混合层矿物和伊利石/蒙脱石不规则混合层矿物。在粘土中发现了混合层粘土矿物,这为伊利石和蒙脱石之间的转变提供了依据。 Spiced slope clay is a kind of clay weathered by the quartzite porphyry. The clay is mainly composed of kaolinite, montmorillonite and illite, with a small amount of mixed-layer clay minerals associated. Mixed-layer clay minerals were identified by X-ray diffraction after treatment with ethylene glycol and heating to 520 ° C. (1.5 h), which are illite-smectite regular mixed-layer minerals and illite / smectite irregularly mixed layer minerals . A mixed layer of clay minerals was found in the clay, which provided the basis for the transition between illite and montmorillonite.
