UM1972-08-O:CaFeNdTiYZr

This page is currently not sponsored. Click here to sponsor this page.
Formula:
(Fe,Ca,Y,REE)(Ti,Zr)O5
(Fe,Y,REE,Ca)(Ti,Zr)2O5 according to the original paper
"Phase Y" from the Apollo 15 landing site, The Moon (a basaltic rock). Possibly an Fe analogue of armalcolite? Associated with baddeleyite, whitlockite, K-Ba feldspar, and rhyolitic glass.

Very similar to "Phase X" ('Unnamed (Fe-Ti-(Zr) oxide I)') from Apollo 14 rock.

Occurrence, crystal habit and optical properties similar to that of tranquillityite. Also similar to zirconolite.

Crystals, 12-40 microns in size; rectangular or sheaf-like grains.
