Explain Loess
Loess Technical Terms
Loess: Material transported and deposited by wind and consisting predominantly of silt-size particles. Commonly a loess deposit thins and the mean-particle size decreases as distance from the source area increases. Loess sources are dominantly from either glacial meltwaters (i.e. “cold loess”) or from non-glacial, arid environments, such as deserts (i.e. ”hot loess”). [soil survey] Several types of loess deposits can be recognized based on mineralogical composition (calcareous loess, non-calcareous loess). SW & GSST
