The loess sediments from selected localities were divided into four sub-groups based on the characteristics of their heavy mineral fractions. Material of the first sub-group was deflated solely from the weathering horizons of nearby magmatic or metamorphic rocks to the west. The material of the other loess sub-areas was predominantly deflated from sedimentary rocks to the west, southwest, and northwest of their present sites. The sediments with a predominant fine-grained fraction contain exceedingly minimum quartz grains lacking distinctive transport evidence. Nonetheless, it has been possible to use other methods in determining their source rocks.
