| 摘 要： | 辽宁义县地区的岩浆期后充填热液交代型萤石矿床的成矿质量与构造的型式和性质有着密切关系。研究证实,构造性质控制着形成萤石矿床的规模和质量。构造既是成矿热液运移通道,更重要的是提供有效的成矿贮矿空间。背斜构造成矿最好,成群出现近于平行的压扭性断裂构造破碎带次之,这两种性质的构造均能形成具有工业价值的萤石矿床。而张性(张扭性)构造破碎带中只能见到规模较小的萤石矿化。

| Abstract: | The structural type and behavior is related dosely to the ore-forming quality of postmagmatic filled hydrothennal metasomatic fluorite deposit in Yixian Liaoning. The research proved that ,structure is the pathway of hydrothermal ore-forming solution migrating, and provided the available ore-forming space. The scale and quality of the fluorite deposit was controlled by the structural character, anticlinal structure is the best for ore-forming, and the compresso-shear fracture zone occurred in group and approximately paralled is the second, which formed the pay grade fluorite deposit. But only a small scale fluorite mineralization was found in the tenso-shear structural fracture zone. |
