A resistivity survey of phosphate deposits containing hardpan pockets in Oulad Abdoun, Morocco
In the great Oulad Abdoun Basin exploitation of a new phosphate deposit was begun after the Grand Daoui horizon was exhausted. Inclusions of sterile hardpan—so-called “disturbances” —are hard to detect and interfere with phosphate extraction. Their resistivity is above 200 Ω-m as against 80 to 150 Ω...
