This is a slightly calcareous, ferruginous matrix with some angular and sub-angular quartz silt, possibly aeolian in origin. Within the silt fraction are accessory minerals including plagioclase, hornblende, and zircon. Non plastic inclusions are rare and may comprise rounded to angular quartz grains, chalk balls, ferruginous clay nodules, and shell fragments. 

This lithology can be attributed to the loess soils of the Northern Negev or the Shephelah. The lack of distinctive coarse inclusions makes it impossible to tighten the area of provenance.
