小行星与陨石的光谱联系（英文）

A Guide to Asteroid-Meteorite Spectral Links

Bus-DeMeo光谱分类系统中有24种小行星光谱类型以及约27种陨石矿物学类型。小行星和陨石之间的光谱联系在质量和可靠性上差异很大原因主要是某些矿物学中缺乏诊断特征和空间风化作用。将回顾从可见光和近红外光谱中远程获取的小行星矿物学信息,讨论如何从地质学家的角度理解小行星的光谱辨识。

There are 24 asteroid spectral types in the Bus-DeMeo spectral classification system and about 27 meteorite mineralogical types.The spectral links between asteroids and meteorites vary a lot in quality and reliability because of challenges with the lack of diagnostic features in some mineralogies and the effects of space weathering.I will review what can be learned remotely from visible and near-infrared spectroscopy about asteroid mineralogy and how to understand asteroid spectral identifications from a geologist’s point of view.
