Table 10 Characteristics of silty clay in different climatic regions.
From: The geological origins and soil properties of loess-like silty clay: a case study in the jinan area
| Â | Loess-like silty clay | Grey silty clay | Red silty clay |
|---|---|---|---|
Characteristic | 1. Exhibits a higher sand content, with an appearance that ranges from yellow–brown to yellowish-brown 2. Rich in quartz and feldspar, contains a significant amount of montmorillonite, with considerable calcite and minor amounts of amphibole; kaolinite is less common | 1. Typically has a color spectrum ranging from grey to greyish-brown 2.Abundant in illite and kaolinite, with montmorillonite being relatively scarce | 1. Coloration generally spans from red to reddish-brown 2. Enriched in kaolinite, with minimal montmorillonite content, and a certain presence of gibbsite and goethite |
