STUDY ON HETEROGENEITY OF IMPURITIES OF DIAMONDS IN FUXIAN, LIAONING PROVINCE

摘要: 总结了钻石中氮的存在形式及类型、氮的聚集过程及影响因素。对辽宁复县50号岩管中的钻石定向切片进行红外光谱分析，结果显示，同一矿区的钻石具有不同的氮的聚集态和类型;同一粒钻石从中心至边缘亦可出现不同的氮的聚集态。杂质N，H在钻石中分布不均匀，与钻石的成矿环境的变化及多期生长结构相吻合。

Abstract: The aggregation of nitrogen and types, aggregated processes and its related geophysical factors are summarized in the paper, The Fourier transform infrared (FTiR) analysis on diamond plates in Fuxian, liaoning Province, shows that there are different N aggregation states in diamonds of the pipe No. 50 and also in the single diamond. Some of the samples are I aAB type in the core and I aA type in the rim.
The impurities of N and H are revealed heterogeneity in diamond. The conclusion coincides with the variations of environment in upper mantle and the structure of multistage growth of diamonds. Key words diamond, aggregation state of nitrogen, heterogeneity of impurity
- diamond /
- aggregation state of nitrogen /
- heterogeneity of impurity
