摘　　要：本文通过岩矿鉴定、硅酸盐化学分析、稀土元素分析和人工重砂鉴定等手段对青州市马鞍山超基性岩管的岩石矿物学特征进行了系统论述,认为该岩体与典型金伯利岩的物质组分、化学成分等基本相同,其应与金伯利岩同属幔源超基性岩浆岩即为金伯利岩,并从控矿构造、侵位时代等方面对岩管成因进行了初步分析,指明了该地区今后金刚石找矿工作方向和重点部位。This article systematically discusses the mineralogical characteristics of the Ma'anshan ultrabasic rock tube in Qingzhou City through methods such as rock mineral identification,silicate chemical analysis,rare earth element analysis,and artificial heavy sand identification.It is believed that the material composition and chemical composition of this rock body are basically the same as typical kimberlite,and it should belong to the mantle derived ultrabasic magmatic rock,namely kimberlite.The genesis of the rock tube is preliminarily analyzed from the aspects of ore controlling structures,intrusion ages,etc.,indicating the direction and key areas of diamond exploration in the region in the future.
