大冶铁矿床夕卡岩矿物中熔融包裹体的发现及其地质地球化学意义

以显微照片方式报道了对大冶铁矿床夕卡岩矿物中熔融包裹体、熔－流包裹体和流体包裹体的观察结果和对包裹体相态特征的研究结果。结果表明，在所研究的包裹体中，矿物熔融包裹体最为常见，偶见熔－流包裹体和流体包裹体。熔融包裹体在大冶铁矿床夕卡岩矿物中不仅存在而且广泛分布，在偏光显微镜下很容易找到。熔融包裹体的存在对夕卡岩传统的接触交代成因观点具有挑战性，有助于夕卡岩和夕卡岩矿床成因理论研究水平的提高。

Finding of melt inclusion in skarn mineral from Daye iron deposit and its geologic-geochemical significance

Observation on melt inclusions, melt- fluid inclusions and fluid inclusions in skarn minerals from Daye iron deposit and study of their phase states are reported in the shape of microphotographs. The results indicate that melt inclusions are common in the investigated inclusions, but melt- fluid inclusions and fluid inclusions are seldom seen. The melt inclusions in the skarn minerals not only exist, but are widespread, and they can be easily found under polarizing microscope. The existence of the melt inclusions is a challenge to the conception of traditional contact metasomatic genesis of skarn, and has contributed to the improvements of the research level of genesis of skarns and skarn deposits.
