Geochemical Multi-element Database for Geotechnical Habitats
Description
This study aims to explore the influence of parent rock mineral weathering on soil weathering processes and its intrinsic relationship with nutrient supply mechanisms through the regulation of soil physicochemical properties. The research indicates that the mineral composition of parent rocks significantly affects soil weathering intensity and nutrient characteristics. Specifically, the higher the ratio of easily weathered to resistant minerals (E/R) in the parent rock, the faster the weathering rate, the greater the soil weathering intensity, and the higher the clay content, leading to increased soil nutrient levels. There is a strong correlation between weathering characteristics and nutrient characteristics, with clay content being a core factor controlling soil nutrient supply.
