鲁西地区作为华北克拉通的一部分，自古元古代早期（约2400 Ma）二长花岗质岩石侵位以后至晚古生代（约250 Ma），一直处于板内稳定地块状态，在这漫长的2150 Ma年里仅形成了两期脉岩，即四堡期侵位的基性辉绿岩（牛岚单元）与中晚奥陶世侵位的超基性金伯利岩（常马庄单元）。经对控制辉绿岩侵位的构造特征进行研究发现，该构造体系不仅控制了鲁西辉绿岩的侵位，还控制了金伯利岩的侵位。在此基础上，对蒙阴金伯利岩带的控制规律进行了分析，并对金伯利岩带向南延伸的区域进行了初步的预测。

As a part of North China Craton,western Shandong province has been in a stable state from early period of Early Proterozoic monzonite intrusion to later Paleozoic.In the long period from 2400Ma to 250Ma,there were only two periods of vein rocks,that is basic diabase intruded in Sibao period (Niulan u-nit),and ultra basic kimberlite (Chang Mazhuang unit )intruded in middle late Ordovician period. Through study on structural characteristics which controls the intrusion of diabase,it is found that this strucutral system not only controls diabase in western Shandong province,but also controls the intrusion of kimberlite.On these basis,controlling rules of Mengyin kimberlite belt have been analyzed,and areas of southern extension on the kimberlite zone have been predicated primarily.
