Résumé
Denman 002 is a new Australian carbonaceous chondrite. A single stone of
30 g was recovered in 1991 May near Fisher Station on the Trans
Australian Railway, Nullarbor Plain, South Australia (30-degrees-36'S,
130-degrees-04'E). Texture, mineral and chemical composition indicate
that it is a CV3 chondrite of oxidised subgroup with several
similarities to Allende. It is composed of sharply defined chondrules,
Ca-Al rich inclusions up to 3.5 mm across, olivine aggregates and
fine-grained, nearly opaque matrix (40 vol%). Silicates are
compositionally highly heterogeneous (olivine Fa: 0.2-45.6 mol%, PMD:
109.7). Denman 002 shows shock effects of stage S1 and weathering of
category A
