摘 要:本文利用X射线衍射及红外光谱分析,对湘南某钨矿床中黑钨矿进行研究,从矿物化学成分及结构特点出发,结合矿床地质调查,论证黑钨矿特性与成因的相互关系。通过X衍射数据最小二乘拟合解算及红外光谱图分析,证实本区黑钨矿晶胞参数和红外谱图特征,与黑钨矿完全类质同象系列二端员矿物——钨锰矿和钨铁矿相比较,显示过渡状态标型,这种黑钨矿是中温热液成因钨矿床的产物。
Abstract: This paper studies the relationship between the crystal-chemical properties andthe genesis of the wolframite fromatungsten deposit in the south of Hunan Pro-vince with X-ray diffraction and infrared spectrum.The cell parameters have beencalculated by using the least squares method to treat the data of X-ray diffractionof wolframite.Based on the cell parameters and the properties of infrared spectrumof the wolframite,it may be proved that the wolframite in this mine is a transi-tional type of hübnerite and ferberite and a product of mid-temperature hydrothermaltungsten deposit.
