AbstractElectrical resistivity survey has been carried out in (unit 200) in the phosphate complex in Qa'eem western Iraq .33 stations have been occupied, to determine location, depth and lateral extension of caves and solution channels in the unit.
The study revealed four geological zones, with varying resistivity and thickness, the relativity high resistivity at shallow depth in the vicinity near the main control room related to hard soil, while low resistivity values reflect of acid solution to subsurface material.
The apparent resistivity maps and psudosections, probably reflects the presence of longitudinal subsurface cave, located in the mid parallel to main channels. Joints and cracks on the ground surface and inside drainage channels, help it to form continuously.
