摘　　要：金刚石在我国属于稀缺矿产资源,辽宁省瓦房店地区是国内金刚石重要产区之一,所产金刚石矿多为金伯利岩型原生矿床,仅有少数几处中小型近源砂矿。本文探讨了构造运动影响下的金刚石物源供给和金刚石砂矿的成矿模型后,以海平面变化对金刚石砂矿的影响为切入点,探讨了3种水下金刚石砂矿的成矿模型,可为今后的金刚石砂矿找矿工作提供一定的参考依据。Diamond is an important mineral resource which has great industrial and economical values. There are many kimberlite primary deposit,only a few small and medium diamond placers near the primary deposit,in Liaoning Province. This paper discusses the source supply and the mineralization model of diamond placer under the influence of tectonic movement and sea-level change, summarizes three kindes of mineralization model. That can provied reference for future work that prospecting diamond placer.
