山东省金刚石矿中的绿色钻石及其特征

本文论述了山东绿色钻石在金刚石原生矿、次生矿中的含量及绿钻的相关特征,阐述了含绿钻的砾岩层层位特点、松散层中具工业价值的四大矿段特点及绿钻含量。综述认为:山东绿钻既有纯正的绿色,也有复合的绿色、绿斑,透明度好,是宝石首饰业的珍宝,价值极高。初步探讨了次生矿中绿钻的形成时代,为前寒武纪。钻石绿色成因既有地质辐射作用所致,也有含铬引起,或塑性形变产生。山东绿钻无辐射性残留,琢磨后绿色不消失。

The green diamond in Shandong green diamond ore and its characteristics

The paper has discussed green diamond content in original diamond ore, secondary diamond ore about Shandong green diamond and its relevant characteristics, the features of strata position of conglomerate with green diamond and the features of 4 great ore sections in loose strata with industrial value and also green diamond content. With not only pure green color but also complex green color and spits and good transparency, it has been considered comprehensively as a kind of treasure in gemstone and ornament industry of high value. The paper also has stated the formation time of green diamond in secomdary diamond ore is Precambrian, The formation of it has been caused not only by geological radiant action but also by chrome content or plastic deformation. Without radiant remains, the green color of Shandong green diamond has not been disappeared after cutting.
