Abstract Details

2012, Master of Science, Miami University, Geology and Environmental Earth Science.
The Franklin and Sterling Hill deposit is unusual in its wide variety of apatite group minerals. Those in the Ca-(As,P)-(OH,F,Cl) system are of interest to mineralogists for several reasons including their potential use in environmental remediation. The chemistries of 29 samples from this deposit were determined using electron microprobe analysis (EMP), and the structures of 17 of these were determined using single crystal X-ray diffraction (XRD). The samples range in percentage of arsenic occupying the tetrahedral site of the apatite structure from 0.052% to 99.116%. As the amount of arsenic increases, most atomic bond distances within the structures expand, but the Ca1-O1 bond length decreases as a result of steric constraints placed on the oxygen atoms surrounding the Ca1 site by the bonded arrangement of tetrahedron to them. Raman spectra revealed continuous changes in peak positions and intensities associated with vibrational modes of the tetrahedral site along this solid solution.
