Crystallographic information files (CIFs) of omphacite in lawsonite eclogite xenolith from the Colorado Plateau, southwestern USA

This dataset includes single-crystal X-ray diffraction data of 3 omphacite crystals separated from a lawsonite (pseudomorph) eclogite xenolith at Garnet Ridge in the Colorado Plateau. The X-ray diffraction data were collected by using an Oxford Diffraction Xcalibur 2 diffractometer. The system included a CCD detector and graphite-monochromatized Mo-Kɑ radiation operated at 50 kV and 40 mA.
