| 摘 要： | 通过对贵州东部镇远地区的一套偏碱性的基性超基性煌斑岩的矿物学及岩石学研究，发现该套岩石具有多种钾镁煌斑岩的特征矿物和结构：含钛的钾碱镁闪石、钛金云母、低铝透辉石、含铁透长石，以及金云母的嵌晶状结构、橄榄石的＂犬牙＂结构。在岩石地球化学方面，它们与世界典型地区的钾镁煌斑岩相似。根据对比鉴定，将这套岩石定名为：（１）金云母钾镁煌斑岩；（２）含橄榄石嵌晶状钾镁煌斑岩。

| Abstract: | The mineralogical and petrological study on the peralkaline basic lamprophyres in Zhenyuan area, Guizhou Province shows that these rocks contain characteristic minerals of lamproites, such as titanian potassium richterite, madupatic phlogopite, low Al diopside,Fe-bearing sanidine and so on. Despite of heavy alteration, it can be determined that these rocks are similar to standard lamproite in major elements geochemistry. And the trace elements and REE are highly enriched. So,it is suitable to call these diamond-bearing rocks as lamproites. |
