Extract

During the course of recent work on minyulite (KAl2(PO4)2 (OH,F).4H2O) X-ray, optical, and density data were obtained for several hydrous K-Al phosphate minerals. These included one specimen of a soft white compact mineral labelled by P. Pallary as minervite from Sebdou, Orau, Algeria, which was presented in 1940 to the Trustees of the British Museum by Major M. Connolly. Minervite was originally described and analysed in 1895 by A. Carnot from Minerva grotto, Fauzan, dép. Hérault, France. In the same year Carnot also described the same species from Tour-Combes grotto, Misserghin, Oran. Sebdou is some 80 miles SSW. of Oran and geological maps show there a patch of Pliocene on late Jurassic. No doubts were entertained that the specimen under discussion belonged to the same species as minervite from Misserghin, since the geological formations of both localities are closely related.
