Western Makhtesh Ramon: features of relief structure and palaeogeographic reconstructions

The western part of the Makhtesh Ramon (Qarnei Ramon Area) is distinct from its central part in morphostratigraphy and sedimentary characteristics. These differences in morphostratigraphy and sedimentology between the two parts reflect a different history of their development related to the presence of thick and hard volcanic rocks in the Qarnei Ramon area. It is suggested that this hard unit preserved the underlying layers from erosion. After this cover was cut through, the development of this part was subordinated to a common base level. Abundant loess deposition during wetter periods is considered to account for the differences in alluvium composition. -from Author
