| 摘 要： | 高龙金矿床含矿硅质岩的野外宏观特征、镜下组构特征和稀土元素地球化学特征一致表明硅质岩的形成主要与热水沉积作用有关,而非前人认为的断裂破碎 -热液硅化交代岩。岩石化学、稀土元素和微量元素地球化学特征表明,硅质岩可能形成于大陆边缘 -远洋盆地过渡位置,但更靠近大陆边缘的半深海 -深海环境。

| Abstract: | The characteristics of macrolithology, fabric and rare earth elements of the immediate host siliceous rocks from Gaolong Gold Deposit suggest that they are of hydrothermal sedimentary origin, not of fracture breaking-hydrothermal silicified origin. Siliceous rocks probably deposited in transitional area between the continental margin and ocean basin environment, but closed to the continental margin, according to rock chemistry , rare earth elements and trace element geochemistry. |
