Eze, P. N., Knight, J., & Evans, M. (2016). Tracing recent environmental changes and pedogenesis using geochemistry and micromorphology of alluvial soils, Sabie-Sand River Basin, South Africa. Geomorphology, 268, 312-321.
In South Africa studies were done to see changes in the enviroment due to chemical weather, by using geochemical proxies. Sabie River was the precise location they did studies at, due to it being the most biological diverse river. The reason they used geochemical proxies was the evaluation of soil, and it was a highly successful way of determining chemical weathering. Results found by the geochemical proxie, was that Silicon Dioxide was the dominant mineral in the soil, and the conclusion from this and the other studies done, was that soils in the Sabie River were weakly developed. Strong evidence was found that there were effects of aggradation-degradation cycles related to how the climate had been, and the foods. Though even with the studies done, and the gathered research time of the environmental changes along the Sabie River is not established.

In Southern Namibia the mine tailings at Rosh Pinah were investigated, the mine being operated for about 47 years. The climate around the area during the summer is from about 30 to 40C, being considerably hot during then and even during the winter at being about 20 to 25C. Soil in the area having a coarse texture and classified as Haplic Regosols, consisting of pH levels in the alkaline range. Results show that the grounds were well neutralized in the mine tailings, due to an abundance of dolomite, and many minerals were found throughout the land as well in the water.
