摘要:

在过去的十年中,随着实验室光谱校准的进步和航天器交会任务对我们的解释方法的验证,限制小行星表面矿物学的方法有了相当大的发展。这使得能够准确地识别主小行星带中的几个陨石母体,并有助于限制普通陨石和玄武质无球粒陨石中的矿物化学和丰度。由于温度,相位角和晶粒大小,系统的差异,由于非成分因素,现在可以更好地量化光谱的影响,几乎可以消除镁铁质硅酸盐轴承小行星。对光谱上没有特征的小行星的解释仍然是一个挑战。本文对目前使用的所有矿物学解释工具进行了回顾,并概述了其应用程序。

英文摘要:

Methods to constrain the surface mineralogy of asteroids have seen considerable development during the last decade with advancement in laboratory spectral calibrations and validation of our interpretive methodologies by spacecraft rendezvous missions. This has enabled the accurate identification of several meteorite parent bodies in the main asteroid belt and helped constrain the mineral chemistries and abundances in ordinary chondrites and basaltic achondrites. With better quantification of spectral effects due to temperature, phase angle, and grain size, systematic discrepancies due to non-compositional factors can now be virtually eliminated for mafic silicate-bearing asteroids. Interpretation of spectrally featureless asteroids remains a challenge. This paper presents a review of all mineralogical interpretive tools currently in use and outlines procedures for their application.
