CA,AL-RICH INCLUSIONS, AMOEBOID OLIVINE AGGREGATES, AND AL-RICH CHONDRULES FROM THE UNIQUE CARBONACEOUS CHONDRITE ACFER 094: I. MINERALOGY AND PETROLOGY

Krot A.N.; Keil K.; Fagan T.J.; Yurimoto H.; McKeegan K.D.; Sahijpal S.; Hutcheon I.D.; Petaev M.I. (2004)

Based on their mineralogy and petrography, ~200 refractory inclusions studied in the unique carbonaceous chondrite, Acfer 094, can be divided into corundum-rich (0.5%), hibonite-rich (1.1%), grossite-rich (8.5%), compact ...
ORIGIN OF LOW-CA PYROXENE IN AMOEBOID OLIVINE AGGREGATES: EVIDENCE FROM OXYGEN ISOTOPIC COMPOSITIONS

Krot A.N.; Fagan T.J.; Nagashima K.; Yurimoto H.; Petaev M.I. (2005)

Amoeboid olivine aggregates (AOAs) in primitive carbonaceous chondrites consist of forsterite (Fa<2), Fe,Ni-metal, spinel, Al-diopside, anorthite, and rare gehlenitic melilite (Åk<15). ~10% of AOAs contain low-Ca pyroxene ...
OXYGEN ISOTOPIC EVOLUTION OF AMOEBOID OLIVINE AGGREGATES IN THE REDUCED CV3 CHONDRITES EFREMOVKA, VIGARANO, AND LEOVILLE

Fagan T.J.; Yurimoto H.; Krot A.N.; Keil K. (2004)

Amoeboid olivine aggregates (AOAs) from the reduced CV chondrites Efremovka, Vigarano, and Leoville consist of forsteritic olivine, FeNi-metal and a refractory component composed of spinel, Aldiopside, anorthite. Secondary ...
