New analyses of Cr2O3 contents of olivines from type II chondrules in unequilibrated chondrites (UOC) from four dense collections are reported here. This survey of petrologic type 3 UOCs was undertaken to identify primitive chondrites that may have been overlooked, and to address possible pairing errors. We have identified 23 primitive UOCs (≤3.10) (only five identified previously, for a total of 28 overall), and also recommend other revisions to prior classifications and pairings.

南极四个密集收集区非平衡普通球粒陨石的鉴定和配对重新评估

此处报告了对来自四个密集集合的未平衡球粒陨石 (UOC) 中 II 型球粒橄榄石的 Cr 2 O 3含量的新分析。对岩石学类型 3 UOC 进行的这项调查旨在识别可能被忽视的原始球粒陨石,并解决可能的配对错误。我们已经确定了 23 个原始 UOC(≤3.10)(之前仅确定了 5 个,总共 28 个),并且还建议对先前的分类和配对进行其他修订。
