【摘要】 赣西北花山洞钨矿是九岭地区新发现的一新元古代中型钨矿。通过岩相学、矿物学和岩石地球化学研究，将花山洞与九岭花岗岩进行对比，揭示二者岩浆分异演化程度的不同并探讨其钨成矿潜力的差异。不同于九岭花岗岩，花山洞花岗岩的暗色矿物含量明显更少，斜长石牌号明显更小，SiO₂、Na₂O含量更高，FeO_T、MgO、TiO₂含量更低，Zr+Nb+Ce+Y和ΣREE含量以及Th/U比值更低，表明其岩浆分异演化程度更高。花山洞花岗岩中存在氟磷灰石、富F榍石和含W金红石，并且经历了更强的热液蚀变。以上特征都指示花山洞花岗岩比九岭花岗岩具有更大的钨成矿潜力。更多还原

【Abstract】 The Huashandong tungsten deposit in northwestern Jiangxi Province is a recently discovered medium-scale Neoproterozoic tungsten deposit in Jiuling area. A comparative study of the Huashandong and Jiuling granites has been carried out by petrographic, mineralogical, and petrogeochemical investigations to reveal their differences on the degree of magmatic evolution and tungsten mineralizing potential. In contrast to the Jiuling granite, the Huashandong granite contains distinctly less mafic minerals and more sodic plagioclase and higher SiO₂, Na₂O contents, and lower FeO_T, MgO, TiO₂, Zr+Nb+Ce+Y, ΣREE contents, and Th/U ratio, manifesting a higher degree of magmatic evolution. The Huashandong granite contains fluorapatite, F-rich titanite, W-bearing rutile and underwent stronger hydrothermal alteration. All of this indicates that the Huashandong granite has greater potential for tungsten mineralization than the Jiuling granite.更多还原
