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.关键词
