Abstract | ||||
The present work deals with mapping the radioactive heat production from rocks in Gabal (G.) Umm Anab - G. El Dob area at the central Eastern Desert of Egypt, using the airborne spectrometric gamma-ray survey data. The results show that, the radioactive heat production in the areas ranges from 0.14 μWm-3 to 5.50 μWm-3. In the granites, metagabbro to metadiorite in the western part of Gabal Umm Anab has abnormally high radioactive heat production values varying from 2.10 μWm-3 to 4.19 μWm-3. Meanwhile, the higher averages of radioactive heat production of these rock units change from 1.20 μWm-3 to 1.50 μWm-3. The intermediate averages of heat production of Hammamat sediments, metavolcanics, intrusive metagabbro, and Dokhane volcanics have values ranging from 0.80 μWm-3 to 1.20 μWm-3. The lowest average values of heat production less than 0.80 μWm-3 and are found in the Quaternary deposits, metavolcanics, sedimentary rocks, meta sediments, gabbroic rocks (fresh olivine gabbro and troctolite). Umm Mahara Formation, melanocritic medium-to high-grade metamorphic rocks and Taref Formation. | ||||
