dc.description.abstract | The growth structure, period and process of diamond can be revealed by the cathodluminescence (CL) technique. The rare agate-like structure of diamond is first discovered in Mengyin area, Shandong Province, China and its characteristics and genetic mechanism are discussed. The FTIR in-situ analysis of the oriented plate of the diamond shows that there exist heterogeneities of N and H impurities. The total contents of N and percentage of B defects decrease gradually, and the H contents fluctuate irregularly from central to periphery of the diamond. The growth structure and heterogeneities of the impurities indicate participation of melts/fluids and the complexities in growth processes and environments in upper mantle. | |
