This page is currently not sponsored. Click here to sponsor this page.
Formula:
(Gd,Ce,Ca,La,U)4ZrTi2O12
Formerly "Unnamed (Gd-Zr-Ti Oxide II)".

From lunar regolith, Luna 24 landing site, Mare Crisium, as micron-sized particle.

One of few Gd-dominant oxide phases from the Moon. Chemistry similar to that of 'UM2004-28-O:GdTiZr' (also lunar phase). Also compare other lunar phases: 'UM2004-18-O:AlCaGdThTlZr' and 'UM2004-20-O:AlGdLaThTiZr'.
