    • 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
