Scientific paper

The carbonaceous matrix of ureilite meteorites (C-bearing olivine-pigeonite achondrites) contain abundant minute phases that emit a multicolored fluorescence under electron bombardment. These include NaCl and KCl, found in all seven ureilites studied, high-Si glass with pyroxene and chlorapatite quench crystals in North Haig, an unidentified high-Ca-Al-Cl phase in Novo Urei, and possibly free SiO2 in Novo Urei and Dingo Pup Donga. The origin of these phases is uncertain but some, especially chlorides and glass, may represent residual postcumulus materials precipitated from a late-stage interstitial liquid during the igneous phase of ureilite history.
