Comparison between refinement results of apatites from Celia mine (Murcia, Spain) using X-ray diffraction powder and single-crystal data

Abstract

The results of crystal structure refinement of apatites, Ca5(PO4)3(OH,F,Cl), found in Celia mine (Murcia, Spain) using X-ray powder diffraction single crystal data are compared. According chemical and X-ray results these apatites are fluorapatites. Finally this study shows that the X-ray powder diffraction technique can be successfully applied in mineralogy to crystal structure studies with a precision probably sufficient for most purposes.
