Description :
The aim of this study is to delineate and investigate the various forms of yardangs in the Um Al-Rimam depressions in the northern part of Kuwait. On lithological bases, three main types of yardang have been identified: 7 yardangs are sculptured in sandstones of Lower Fars Formation (Lower to Middle Miocene), 23 are carved in calcretic rocks of Ghar Formation (Oligocene to Lower Miocene), and 11 yardangs are developed in Quaternary sediments. It is believed, as indicated from field observation and interpretation of aerial photos, that the majority of yardangs are pre-existing bedrock forms. These forms were developed by paleo-surface hydrological processes which were modified by wind action in latter phase.
