Composition of phosphate containing sediments and phosphatic grains from the Namibian shelf

Recent phosphatic grains from diatomaceous oozes, as well as Pliocene grains from phosphatic sands of the Namibian shelf were studied by a scanning electron microscopy coupled with microprobe analysis. Lithification of the grains occurred together with changes in their composition and structure resu...
