| 中文摘要:辽东硼铁矿床是一处类型独特的超大型矿床。文章对该矿床的地质特征、矿石物质组成、矿床稀土元素和稳定同位素特征及矿化时代进行了研究。研究表明，该矿床的成矿作用主要表现为海底热水沉积成矿，区域变质混合岩化作用对矿床进行了强烈的叠加改造，使硼铁进一步富集而形成工业矿床。 |

| Abstract:The uranium_bearing vonsenite deposit in Liaodong (eastern Liaoning) is a unique and superlarge deposit. In this paper, the authors studied the ore composition, ore_forming epoch, REE characteristics and stable isotopes of this deposit based on a detailed investigation of geological features of this type of deposits. The results indicate that submarine hot water deposition is the main ore_forming process of the uranium_bearing vonsenite deposit, and that the economic deposit was formed on the basis of further enrichment of boron and iron through the superposition and transformation by regional metamorphism and migmatization. |
