Unit cell parameters, compositions and 2V measurements of selected lunar plagioclases

  • 19 Accesses

Abstract

Unit cell parameters of 12 selected lunar plagioclase specimens have been obtained using least-squares refinement of X-ray powder diffraction data. Compositions of splits of 11 of these plagioclase specimens were determined using the electron microprobe. Optical axial angles were measured on analyzed spots for nine of the probed specimens. Analyses cluster about An 96.5 ± 1.0 and unit cell parameters and 2V x fit the values for this composition obtained in other studies.
