Geology of the Al Hamra 1:100 000 map sheet, 100-14, United Arab Emirates

This Sheet Description describes the Quaternary geology of the Al Hamra 1:100 000 scale geological map. About 70 observation points were made throughout the Al Hamra district, which covers 2500 km2 of country in the south-east corner of the UAE. No pre-Quaternary bedrock exposures were identified in the district, which contains a variety of active, aeolian sand deposits in different morphological forms, including fields of high barchans, sand sheets and low dunes. High dune ridges separated by elongate sabkha pans extend a few kilometres westwards across the eastern boundary of the sheet. Madinat Zayed Formation (MZ) aeolianites crop-out within small, deep interdune hollows within the extensive sand sea that dominates most of the district. The area has no known economic mineral deposits.
