摘要
本文通过对辽宁金伯利岩中具环带构造的金刚石中包裹体的研究,发现了国内外均未报道过的复杂成分的包体组合。其中包括石英、长石、氧化物、硫化物、碳酸盐、硫酸盐、硅铝质玻璃及球体等,具有明显的壳源物质特征。这说明金刚石可形成于温度、压力较低的地壳环境,金伯利岩不仅是金刚石的载体,也可以是金刚石的源岩。
A new kind of chemically complex diamond inclusion suite has been found in the Fuxian diamond formation in Liaoning Province. The diamonds in this formation possess a ring-like structure. The diamond inclusions include quatz, feldspar, oxide, sulfide, carbonate, silica-aluminium glass, and some spheres, reflecting a crustal geochemical environment. This shows that diamonds may be formed at a relatively low temperature and pressure in crustal environment. The kimberlite is not only the carrier of diamond,but also the parent rock of diamond.
