2010年12月1日 · In a recently published Pb isotopic study of a CAI from CV chondrite NWA 2364, Bouvier and Wadhwa (2010) proposed to use the Th/U or Nd/U ratios as proxies to U isotopic variations on the basis of correlations between 238 U/ 235 U and 232 Th/ 238 U or 144 Nd/ 238 U ratios in CAIs reported by Brennecka et al. (2010a) that have been attributed to ...
We recently described a cm-sized lithic inclusion (LI) in the NWA 2364 CV3OxA chon-drite that shows significant evidence of secondary al-teration and metasomatism [7,8]. In this study, we have used trace element analyses by LA-ICP-MS and syn-chrotron-based XANES of Cr, Ti and V valences to understand the complex alteration of the LI more fully.

陨石中发现太阳系最古老物质 - 科学网
2010年8月26日 · 2004年,科学家在摩洛哥发现了一块重达3磅(约合1.5公斤)的地外陨石,给其编号为NWA 2364。 经过最初的分析,科学家原本以为这块陨石来自于火星和木星之间的一个小行星带。 然而,最新测试结果表明,陨石内残留的矿物块(称为钙铝内含物)形成于小行星带存在之前。 它们可能是在部分星际气体和尘云或星云崩溃形成太阳之后才形成的,这一结论与一种太阳形成理论的说法相吻合。 美国亚利桑那州立大学陨石研究中心助理研究员奥德丽·布维 …
Here we describe the structure, mineralogy and petrology of a very large, deformed Ca-, Al-rich inclusion in a new CV3 chondrite, NWA 2364 (CV3) AMNH 5035. This remarkable CAI is 18mm in largest apparent diameter, appears cup-shaped (hence “the crucible”), and envelops a portion of the host chondrite.
