摘    要:通过成矿地质背景,矿体地质特征,矿石特征,矿床稀土元素,流体包裹体地球化学,氢氧同位素地球化学特征等研究,认为八面山萤石矿床,按矿体赋存于岩体与灰岩接触带、灰岩层间及构造破碎带;岩石有细粒及粗粒-巨晶两类;矿床成矿温度主要集中在120°~240°之间;氢氧同位素特征反应成矿流体具有多来源多成因的特征;成矿物质Ca主要来源于寒武系中的灰岩与泥质灰岩,F主要来源于寒武系泥质灰岩,部分可能为岩浆热液从地表深部携带而来,萤石矿床成矿流体水具有多源性;成矿流体具有大气降水,变质水和岩浆水共同混合作用的结果,在岩浆侵入热源的作用下,三种水混合后被加热,形成了成矿溶液的重要载体。研究认为八面山萤石矿床是受地层-岩体-断裂共同控制"三位一体"的中低温热液成因矿床。

关 键 词:萤石矿床  矿床成因  浙江常山

Abstract:This paper studied the geologic background of mineralization, geological feature of orebody, ore characters, characters of REE and fluid inclusion geochemistry, oxygen isotope geochemistry of Bamianshan fluorite deposit. The ore bodies hosted in contact zone of rock mass and limestone, interstratal of limestone and structural fracture zone , there are two rock types which are fine grained and coarse-grained, the mineralization temperature ranges mainly between 120°~240°; Oxygen and hydrogen isotope characteristics suggest that Ca mainly came from limestone and aregiUaceous limestone , F came mainly from aregillaceous limestone in Cambrain System and partly came from magmatic hydrothermal fluid carrying from deep part of the earth's surface. The magmatic water mixed with metamorphic and meteoritic water, heated during the process of magma intrusion, which formed the important carder of ore-forming solution. This research showed that the Bamianshan fluorite deposit is a middle -low temperature genesis and it is controlled by stratum together with rock mass and fracture.
Keywords:fluorite deposit  genesis of deposit  Zhejiang Changshan
