AMIS0055 Uraniferous phosphatic sandstone, 3423 ppm U, 21.22% P2O5, Bakouma, CAR

Normal 0 false false false EN-ZA X-NONE X-NONE

Origin of Material:  This material was supplied by Uramin Inc. from their Patricia prospect located 4 km north of the town of Bakouma in the Mbomou district of the Central African Republic, 550 km east of the capital Bangui and 100 km north of the district administrative centre of Bangassou. The mineralisation has been known since the early 1960s and was extensively explored throughout the 1960s and 1970s. It occurs in Late Cretaceous to Eocene Phosphatic kaarst sediments of the M’Patou Formation.  These comprise thick black shales with pyrite and abundant organic matter, overlain by a 20-25 m thick succession with brown, reddish and yellow phosphatic lenses.

Mineral and Chemical Composition: Phosphates occur in the form of microcrystalline, carbonate-substituted fluorapatites that can make up as much as 50% of the rock. The phosphate lenses are highly weathered and contain secondary Al-phosphates.

 

 

The main uraniferous phosphate minerals appear to be autunite and torbernite. Autunite is bright yellow in colour and torbernite is bright green. These minerals have been observed as fracture coatings, and fine-grained disseminations. White indurated masses of crandallite (alumina phosphate), have also been documented.
