| Abstract: | The diamond placer of Xinyi lies in the next Pleistocene series, Wangwei Group, the plane is controlled by the ancient Yi River, the vertical direction is mainly located in the gravel layer in the bottom of Wang Wei group, and deposite on the favorable site of the ancient Yi River, forming Quaternary diamond placer in this area. One material source of diamond is primary diamond mines and ancient placer in the ancient Yi River upstream in Shandong, the other is the primary diamond mine which may exist in this area. |
