Abstract：Diamond has excellent physical and chemical properties, which is an important raw material for the development of new industries. The diamond resource is a kind of dominant mineral in Shandong Province, and the study of diamond deposits in Shandong is still under controversy. Through the systematic explanations of diamond deposits in Shandong Province, the authors in this paper discussed the distribution regularity, mineralization geological condition and mineralization age, and summarized the central points of three diamond primary ore belts in Mengyin, which the connecting line is a broken line protruding from the north to the west after connection, with directionality, equidistance and left-column distribution regularity. The lithology of the three rock belts changes from south to north with the regularity of rich in the south and poor in the north, rich in the middle and poor in both sides. It is believed that the shape of the primary diamond deposit in Mengyin area of Shandong Province were veined and tubular, and the genetic type is magmatic, of which the invasion era was mainly in Mesozoic. This research would provide important reference in diamond prospecting, by summarizing the minerogenetic environment, minerogenetic regularity and minerogenetic epoch.
