| 中文摘要:文章从区域成矿理论出发，分析了含硼岩系、镁质容矿岩石、区域变质及混合岩化热液交代作用、构造控制和改造等4大控矿因素在成矿过程中的作用。研究表明，含硼岩系、镁质容矿岩石是硼矿形成的物质基础，区域变质及混合岩化作用、构造改造活动是硼矿形成的必要条件；辽东_吉南硼矿的成矿作用为原始火山_沉积初始富集和部分熔融含硼热液交代镁质岩石的成矿作用过程。 |

| Abstract:From the viewpoint of regional ore_forming theory, the authors analyzed boron_bearing rock sequence, magnesian host rocks, regional metamorphism, migmatitization and tectonism, and the result shows that the boron_bearing rock sequence and the magnesian rocks constituted the basis for the formation of the borate deposits, whereas regional metamorphism, migmatitization and tectonism made up the necessary conditions. The ore_forming mechanism of the borate deposits in eastern Liaoning and southern Jilin lies in the enrichment of boron in primary volcanic sedimentary rocks and the metamorphic hydrothermal reaction between the boron_bearing fluid and the magnesian rocks during regional metamorphism, migmatitization and tectonism. |
