- Аннотация: The ungrouped chondrites have attracted a lot of attention recently. This group includes highly reduced chondrites such as Acfer 370 [1] and even more reduced ungrouped chondrite El Médano 301 (EM 301) [2]. Acfer 370, an ungrouped chondrite of petrologic type 3 [1] and NWA 7135, an ungrouped chondrite of petrologic type 3/4 [3], that show affinities with dark chondritic clasts in the Cumberland Falls aubrite (CFC) [4]. Other chondrites, defined as low-FeO ordinary chondrites, have OC whole-rock chemical composition but olivine and pyroxene richer in Mg than OCs [5]. It was suggested that these clasts are the fragments of an otherwise unsampled ‘‘F chondrite” (F for ‘‘Forsterite”) parent body which upon a collision with the aubrite parent body led to the formation of Cumberland Falls polymict breccia [5]. Chondritic clasts inside IIE iron meteorites (also reduced), defined as HH chondrites, with reduced olivine and pyroxene compositions and higher concentration of siderophile elements than OCs, are thought to be fragments of a different parent body than H chondrites [6-8]. Here we report results on investigation of a new ungrouped chondrite from Chile, Chug Chug 086 (CC 086), and discuss its affinities with other reduced ungrouped chondrites.
