DISCOVERY OF METEORITIC LAKARGIITE (CaZrO3), A NEW ULTRAREFRCTORY MINERAL FROM THE ACFER 094 CARBONACEOUS CHONDRITE

Introduction: During a nano-mineralogy investigation of the Acfer 094 carbonaceous chondrite, lakargiite (CaZrO3) was identified as submicrometer inclusions in an isolated hibonite grain in section USNM 7233-1. The hibonite grain is described in Simon and Grossman [1]. Lakargiite is a recently found perovskite-group mineral from hightemperature skarns in ignimbrites of the Upper-Chegem volcanic...
