摘要

我们使用纳米红外、扫描电镜和 TEM 显微镜分析了 JAXA 的隼鸟 2 号任务返回地球的小行星龙宫样本。我们在植硅酸盐基质中发现了多个不同的碳库，并展示了部分碳与不溶性有机物（IOM）的红外光谱亲和性。对龙宫样本的 TEM 研究使我们能够更好地理解植硅酸盐的晶体学取向与碳酸盐、硫化物和磷灰石等次生矿物之间的相互关系。元素的迁移为理解这些相互关系提供了一个统一的主题。

Coevolution of phyllosilicate, carbon, sulfide, and apatite in Ryugu's parent body

We analyzed an asteroid Ryugu sample returned to Earth by JAXA's Hayabusa2 mission using nanoIR, SEM, and TEM microscopy. We identified multiple distinct carbon reservoirs within the phyllosilicate matrix and demonstrate infrared spectral affinities for some of the carbon to insoluble organic matter (IOM). TEM studies of Ryugu samples have allowed us to better understand the interrelationship between the crystallographic orientations of phyllosilicates and the secondary minerals such as carbonate, sulfide, and apatite. Transport of elements provides a unifying theme for understanding these interrelationships.

期刊介绍： First issued in 1953, the journal publishes research articles describing the latest results of new studies, invited reviews of major topics in planetary science, editorials on issues of current interest in the field, and book reviews. The publications are original, not considered for publication elsewhere, and undergo peer-review. The topics include the origin and history of the solar system, planets and natural satellites, interplanetary dust and interstellar medium, lunar samples, meteors, and meteorites, asteroids, comets, craters, and tektites. Our authors and editors are professional scientists representing numerous disciplines, including astronomy, astrophysics, physics, geophysics, chemistry, isotope geochemistry, mineralogy, earth science, geology, and biology. MAPS has subscribers in over 40 countries. Fifty percent of MAPS'' readers are based outside the USA. The journal is available in hard copy and online.
