Primary minerals of the parent material undergo weathering during the formation of terrestrial soils to varying extent. As a result, secondary minerals develop, which comprise, among many others, hydroxy‐interlayered minerals (HIMs). These minerals have formed by interlayering of hydroxy‐metal complexes (especially of Al³⁺, also Mg²⁺, Fe^2+/3+) into micas, expansible 2:1 phyllosilicates and forming oligomers, or by weathering of primary chlorite. The degree of interlayer filling and the stability of these fillings affect several physico‐chemical soil properties, for instance the cation exchange capacity. Although many studies have been conducted on formation, occurrence, and properties of HIMs in soil during the last decades, several challenges still exist. These challenges include analytical identification and quantification of HIMs in soil, the nature of the interlayer filling and the identification of favorable conditions in soil for the formation of HIMs. In order to deepen the understanding of formation, properties, and fate of HIMs in soil, we critically reviewed the available literature. Based on the review, we recommend using a new structural model that enables quantification of hydroxy‐interlayered smectite in soil by X‐ray diffractometry, laboratory experiments on the formation and preservation of different types of interlayers and considering the temporal and spatial dimension of the formation of HIMs in soil in more detail.

评论文章。土壤中的羟基夹层矿物（HIM）的性质和形成条件是什么？

母体材料的主要矿物在陆地土壤形成过程中经历了不同程度的风化。结果，形成了次生矿物，其中包括羟基中间层矿物（HIM）。这些矿物质已经通过羟基金属络合物的interlayering（尤其是铝的形成³⁺，也镁²⁺，铁^{2 + / 3 +}）变成云母，可膨胀的2：1层状硅酸盐并形成低聚物，或通过风化原始亚氯酸盐。层间填充的程度和这些填充物的稳定性会影响一些物理化学土壤特性，例如阳离子交换能力。尽管在过去的几十年中对土壤中HIM的形成，发生和性质进行了许多研究，但仍然存在一些挑战。这些挑战包括对土壤中HIM的分析鉴定和定量，层间填充的性质以及在土壤中形成HIM的有利条件的鉴定。为了加深对土壤中HIM的形成，性质和归宿的了解，我们严格审查了现有文献。根据评论，
