Fig. 3

Correlation of the Ca and P intensities for apatite phases obtained at 15 kV using the Mini-SEM. The data of the reference materials, SAp and MAp, show constant and straight lines. The slope of the trend line from BAp indicates lower Ca/P compared to SAp and MAp. FAp shows certain data points distributed outside the line, which suggests the presence of Ca-rich minerals other than apatite, such as calcite (CaCO3)
