Phosphate minerals from Albian phosphorites in Bulgaria
Geologica Balcanica, 2002 Results from X-ray diffraction analyses of Albian phosphorites from deposits Sanadinovo, Dekoy and Brushlen indicate presence mainly of fluorapatite and partly of chlorapatite and carbonate fluorapatite (francolite). The microprobe analyses of phosphate grains, coatings, cements, ammonite, wood, and shark tooth determined the following contents (in ...
