Jizan area is considered as one of the
most promising geothermal targets which are characterized by the presence of a number of
structural related hot springs with a surface temperature range of 46 to 79 C at the surface. Three main thermal anomalies are recognized (Al Ardah, Al Khouba and Bani Malik), and more closely located to the east, away from the coastal plain in areas of high and complicated topographic nature, and originating from hard crystalline rocks. The general slope decreases notably westward from 45° in the high hill areas to 1° near the sea coast. The studied hot springs are promised and needs to be further investigated and accessed by additional geophysical methodologies. |
