Analysis of phosphate deposit “disturbances” using the horizontal-gradient responses of resistivity data (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 8...
