阴极发光（ＣＬ）图像揭示辽宁瓦房店金刚石内部结构具有３种类型：（１）简单的生长环带结构，（２）复杂环带的多期生长结构，（３）罕见的“似玛瑙状”结构．这些特点反映了金刚石生长过程的复杂性．定向切片金刚石的微区Ｆｏｕｒｉｅｒ变换红外光谱（ＦＴＩＲ）分析表明：杂质Ｎ，Ｈ在金刚石中分布不均匀，同一矿区的金刚石具有不同的氮聚集状态和类型，同一颗粒金刚石从中心至边缘亦可出现不同的Ｎ聚集态，Ｎ的不同聚集态是聚集温度Ｔ_（ＮＡ）金刚石在地幔中存留时间ｔ_（ＭＲ）及Ｎ丰度值的函数，结合ＦＴＩＲ定量分析结果和相关地质信息，得知瓦房店金刚石中心与边缘结晶时间相差最高可达６～７亿年，如此长的生长时间跨度与ＣＬ图像揭示的多期生长结构相吻合．
Cathodoluminescence (CL) images reveal three types of diamond internal structures in Wafangdian, Liaoning Province: (1) simple growth zone structures, (2) multi-stage growth structures of complex zones, (3) rare “agate-like ”structure. These characteristics reflect the complexity of the diamond growth process. The Fourier transform infrared spectroscopy (FTIR) analysis of oriented diamond shows that the impurities N and H are distributed unevenly in the diamond, and the diamonds in the same mining area have different nitrogen accumulation states and types. The same diamond can appear from the center to the edge Different N aggregation states and N different aggregation states are a function of the T_ (MR) and N abundance values of the accumulation temperature T_ (NA) diamond in the mantle. Combined with the FTIR quantitative analysis results and relevant geological information, it is known that the Wafang The difference between the diamond center of the shop and the edge crystallization time can reach as high as 600 million to 700 million years. Such a long span of growth period is consistent with the multi-period growth structure revealed by the CL image.
