Journal Article: Geothermal Gradients And Heat Flow Trends In Morocco

The paper presents a map of the main trends of heat flow density in Morocco. The average thermal gradients are also drawn for each major geological unit. The highest anomaly is observed in north-eastern Morocco, with a gradient of 30-40°C km-1 and a HFD of 70-110 mW m-2. In the south, the Atlantic margin presents a gradient of 23-34°C km-1 and a HFD of 65-85 mW m-2. The Saharan coastal basins show a gradient of 20-30°C km-1 and a HFD of 60-90 mW m-2, finally, in the Tindouf basin, the average gradient and HFD are, respectively, 20-34°C km-1 and 70-100 mW m-2. Two main axes of HFD anomaly may be identified on both sides of the South Atlasic fault. In the north a NE-SW axis extends from the Middle Atlas, Eastern Rif to the Alboran sea and SE Spain: this direction also corresponds to an intensive Plio-Quaternary volcanic and neotectonic activity. In the south an E-W thermal feature extending from the Canary Islands to Tindouf basin continues in the Algerian Southern Sahara.
