The deposit is limited by the Ha’il arch complex in the east, Wadi Sirhan, Quraymiz area in the South, and Iraqi and Jordanian borders in the north and the west.

In the Al Khabra area, the Arqah Phosphorite member is repeatedly exposed by the set of northwest trending faults. The member varies in thickness from 1.3 metres to 5.6 metres and averages 3.09 metres. The phosphates layers comprise an original succession of carbonate-cemented sub-cycles, now represented by friable, semi-friable and residual carbonate-cemented phosphorite. Graded bedding is ubiquitous; with the pelletal grain size decreasing upwards in successive sub-cycles (fining upwards). Occasional barren limestone and chert interbeds are documented within the phosphorite sequence.
