We present here a review of the characteristics of CR carbonaceous chondrite meteorites. Over the past three decades, our knowledge and understanding of the scientific value of the CR chondrites have increased dramatically, as more samples from cold and hot deserts have become available for analysis. Based on a variety of compositional, mineralogical, isotopic, and spectroscopic studies, we have come to understand that CR chondrites are excellent samples of asteroidal meteorites to look for virtually unaltered solar nebula material and to observe asteroidal processes in progress. This paper summarizes these investigations, their similarities, and differences with other chondritic groups, their relationships to asteroids, and the questions yet to be addressed.

我们在这里介绍CR碳质球粒陨石的特征。在过去的三十年中，随着越来越多的来自冷漠和炎热沙漠的样本可供分析，我们对CR球粒陨石的科学价值的了解和了解急剧增加。基于各种组成，矿物学，同位素和光谱学研究，我们已经了解到CR陨石是小行星陨石的极佳样本，可以寻找几乎未改变的太阳星云物质并观察正在进行的小行星过程。本文总结了这些研究，它们与其他软骨组织的相似性和差异，它们与小行星的关系以及尚待解决的问题。
