山东蒙阴地区盛产金刚石，一直受到国内外地质学家关注。近年来的勘查和研究表明，该区 NW走向的金伯利岩不是以往认为的岩脉，而是岩床，并根据赋存层位发现了新的金伯利岩床———珍宝1号。在此基础上，研究了岩床的微量元素特征，并根据构造的切割与地层展布特征恢复了白垩纪晚期时的原始地貌，对岩床的岩浆来源进行了分析。
山東矇陰地區盛產金剛石，一直受到國內外地質學傢關註。近年來的勘查和研究錶明，該區 NW走嚮的金伯利巖不是以往認為的巖脈，而是巖床，併根據賦存層位髮現瞭新的金伯利巖床———珍寶1號。在此基礎上，研究瞭巖床的微量元素特徵，併根據構造的切割與地層展佈特徵恢複瞭白堊紀晚期時的原始地貌，對巖床的巖漿來源進行瞭分析。

Diamond is very rich in Mengyin area of Shandong province.It has been concerned by domestic and foreign geologists.As showed by exploration and research,it is regarded that kimberlite rocks with the trend of NW in this region are deposits,not rock veins.According to occurrence layers,new limberlite bedrock has been found and named as No.1 treasure.On this basis,characteristics of trace elements in the bedrock have been studied.According to the cutting and distribution characteristics of structures,the orig-inal landscape restoration in late Cretaceous age has been carried out,and magma source of the bedrock has been analyzed as well.
