为了解辽东硼矿的成矿机制及建立成矿模式,分析了含硼岩系、镁质容矿岩石、区域变质作用及混合岩化作用、构造等四大控矿因素,发现含硼岩系具富硼特征,容矿岩石具富镁特点并可成为硼质的沉淀剂,含硼岩系中硼在区域变质和混合岩化过程中得到进一步活化形成含硼热液,含硼热液在有利的构造空间交代镁质岩石即可形成镁硼酸盐型硼矿.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、构造活动是硼矿形成的必要条件.辽东硼矿成矿模式为原始火山-沉积初始富集和部分熔融含硼热液交代镁质岩石.
In order to understand the ore-forming mechanism of boron mine in Liaodong and to establish metallogenic model, the authors analyzed four major ore-controlling factors including boron-bearing rock series, magnesia-hosted ore, regional metamorphism, mixed petrification, and tectonism. Boron-bearing rocks are characterized by rich boron and rich in magnesium, which can become boron precipitates. Boron in the boron-bearing rocks is further activated during the regional metamorphism and mixed rock formation to form boron-bearing hydrothermal fluids. The favorable tectonic space can account for the magnesian rock to form the magnesium borate type boron mine.The boron-bearing rock series and magnesia-bearing mineral rock are the material basis, regional metamorphism and migmatization of boron mineralization, and the tectonic activity is boron ore The formation of the necessary conditions.Liaodong boron ore-forming model for the original volcano-sedimentary initial enrichment and partial melting of boron bearing hydrothermal metasomatic rocks.
