| 摘 要： | 通过对云南川滥泥坪矿区因民组顶部硅质岩的产状，常量元素，微量元素，稀土元素，氧同位素等地球化学特征进行综合研究，表明其成因应为海底喷流热水沉积产物。该硅质岩层还含较富的铜矿体，根据地质条件相似性原则，指出了找矿方向。

| Abstract: | Integration of geochemical study on normal and micro-element, REE, isotopes and occurranes of siliceous rock at top of Yinmin Formation in Lanniping Mine Area suggests that the siliceous rock is the product of submarine hydrothermal sedimentation.Rich copper ore bodies occur in the siliceous rock.By correlation to it Cu-ore prospecting direction in the area is pointed out. |
