Resumen:
Cell dimensions of five apatite-group minerals from the Velasco Pegmatitic District, La Rioja Province (Argentina), were refined from X-ray diffraction data. The results are: a = 9.3546 9.371 Å and c = 6.8524 6.880 Å. Based on this, it is inferred that F is an important anion (besides oxygen) and some Mn is substituting for Ca.
