Abstract

The aims of this study were (1) to determine the influence of loess mineral composition on soil genesis and (2) to determine layer silicate transformations and clay mineral formation in loess soils in relation to soil-forming processes using qualitative and quantitative X-ray diffraction analyses (XRD and QXRD). The obtained results show that the occurrence of carbonate minerals (i.e. calcite) and their influence on chemical properties of soil play a crucial role in the evolution of loess soils. It is highlighted that carbonates and high pH values are the main reasons for slowdown of mineral weathering. In carbonate loess, the dissolution and leaching of carbonates prevail over the weathering of silicates
