What is the name of the premier agricultural sedimentary sandstone aquifer in northwestern Saudi Arabia, which has historically supplied groundwater for Tabuk and Al-Jawf?
Answer and explanation
Correct answer: B. Saq Sandstone Aquifer
- Step 1: Identify hydrostratigraphic formations: The Saq Formation is a Cambro-Ordovician sandstone extending across northern Saudi Arabia into Jordan (where it is called the Disi aquifer).
- Step 2: The Saq Sandstone Aquifer holds immense volumes of paleo-water, making it the most heavily used fossil aquifer for large-scale pivot irrigation in Tabuk and Al-Qassim.
Answer
Saq Sandstone Aquifer.
Why not the others: 'Wasia' and 'Biyadh' are Cretaceous sandstone aquifers in the eastern and central regions; 'Minjur' is a Triassic sandstone aquifer supplying parts of Riyadh.
