Yes, it is also often reffered to as 'sulphospurrite' which is rather imprecise. It
forms extensive solid solution with silicocarnotite and also with the apatite-
ellestadite series.
See Pliego-Cuervo, Y. and Glasser, F. P. (1978): "Phase relations and crystal
chemistry of apatite and silicocarnotite solid solutions", Cement and Concrete
Research, vol. 8, 519-524.
