摘　　要：辽东地区硼矿赋存于以“含硼岩系”而著称的辽河群里尔峪(岩)组中,表现出明显的地层岩性控矿性.在广泛搜集前人有关硼矿研究成果的基础上,结合丹东市1/25万区调,对本区硼矿成因进行了较深入的研究,认为本区硼矿是混合岩化成矿—构造再次富集的层控型矿床.进而对硼矿成矿远景区进行了预测,共划分A、B、C三级预测区,A级1处,B级3处,C级3处,为今后硼矿找寻、立项提供了科学的依据.The boron deposits in Eastern Liaoning Province occur in Liaohe Group Lieryu formation, which is famous as the “boron-bearing rock series”, showing obvious control by stratic lithology. Based on previous researches, combining with the data from regional geological surveying of 1 ： 250 000 in Dandong area, the origin of the boron deposits is studied.The deposits in this area are migmatized origin and enriched in later tectonic-metallogenic epoch, forming stratabound deposits. The potential area for boron deposits are divided into three classes. It will provide scientific basis for boron deposit searching in the area.
