Abstract

A field experiment was conducted to study the initial stages of chloritization (aluminization) of smectite (fraction <1 μm) with various composition of interlayers in the AELoa horizon of the podzolic soil in the course of current pedogenesis. Application of XRD analysis coupled with the simulation of experimental diffraction patterns led us to a conclusion that during one-year incubation in the soil, Na-smectite was chloritized, and the degree of Na–Al-smectite chloritization increased. Smectite chloritization results in the formation of a disordered mixed-layer mineral comprising smectite layers and layers with interlayer spaces partially filled with aluminum polyhydroxycations and Ca²⁺ cations. A discrete phase of soil chlorite has not been formed during one year of the experiment.

模型田间实验中坡地土壤腐殖质-坡度范围内蒙脱石绿泥化的初始阶段

摘要

进行了野外实验，研究了在当前成岩过程中，绿豆（分数<1μm）具有不同中间层夹层的蒙脱石的氯化（铝化）的初始阶段。X射线衍射分析的应用以及对实验衍射图样的模拟得出了一个结论，即在土壤中培养1年后，蒙脱石被氯化了，Na-Al蒙脱石的氯化度增加了。蒙脱石的氯化作用导致形成包括蒙脱石层和层间空间部分填充有铝多羟基阳离子和Ca ²⁺阳离子的层的无序混合层矿物。在实验的一年中，没有形成离散的亚氯酸盐相。
