近年来对陨石和月球样品中稀土元素(REE)的研究做了大量的工作,取得了大量的分析数据,从理论和实验两个方面进行了广泛的研究。陨石为我们提供了原始太阳系最好的标本,由于球粒陨石缺乏内生火成作用过程,因而保存了太阳系形成最早期事件的证据。无球粒陨石和铁石陨石代表了陨石母体内生火成作用的特点,如部分熔融和分异结晶作用。月球样品主要代表了行星的演化过程。陨石中REE的研究主要集中在陨石,特别是球粒陨石,近年来对球粒陨石中包体做了大量的工作。为了
In recent years, a great deal of work has been done on the research of rare earth elements (REEs) in meteorites and lunar samples. A great deal of analytical data have been obtained, and extensive research has been carried out both theoretically and experimentally. Meteorites provide us with the best samples of the original solar system, and chondrites lack evidence of endogenous firing, preserving evidence of the earliest events in the solar system. Non-chondrites and meteorites represent the characteristics of exogenic reactions within the meteorite matrix, such as partial melting and differential crystallization. The lunar sample mainly represents the evolution of the planet. The research of REE in meteorites mainly focuses on meteorites, especially chondrites. In recent years, a great deal of work has been done on inclusions in chondrules. in order to
