The geothermal resources of the Kingdom of Saudi Arabia
are mainly located along the western and southwestern
coastal parts. These resources are associated with the main
tectonic activities and elements that are prevailing during
the opening of the Red Sea and Gulf of Suez rift. The Al-
Lith area is one of the most promised geothermal targets,
which is located along the western coast of the Red Sea,
about 180 km south of Jeddah city. Four main hot springs
(Ain A1 Harrah, Bani Hilal, Wadi Markub and Al Darakah)
with a surface temperature range from 41oC to 96 oC, are
encountered this area and originating from deep-seated
highly altered granitic rocks.
