Geothermal energy resources of wadi Al-Lith, Saudi Arabia

Lashin, A. and Chandrasekharam, D. and Al Arifi, N. and Al Bassam, A. and Varun, C. (2014) Geothermal energy resources of wadi Al-Lith, Saudi Arabia. Journal of African Earth Sciences, 97. pp. 357-367. ISSN 1464-343X

Abstract

The entire western Arabian shield is the domain of both hydrothermal and enhanced geothermal systems associated with volcanic centres (Harrats) and high heat generating granites. The most prominent sites of hydrothermal systems are located around Al-Lith and Jizan. The hydrothermal system in Al Lith is controlled by high heat generating (~11μW/m 3 ) post orogenic granites. The high heat flow value of >80mW/m 2 across Al-Lith coast is due to such granite intrusives, presence of dike swarms that intrude into the granites as well as position of Moho at shallow level. Although the thermal waters are chloride rich, Red Sea involvement is not observed. Long residence time and water rock interaction with granites are the main processes responsible for chloride enrichment in the thermal waters. Oxygen isotope shift indicates presence of high temperature geothermal system in the area. The tritium values indicate that the circulating waters are >75years old.
