| 摘 要： | 斗南锰矿是滇东南地区大型的沉积型锰矿床,对其沉积成因的研究可反映滇东南地区沉积型锰矿床的成矿模式。笔者对采自斗南锰矿床的条带状锰矿石样品,进行了系统的锰矿石物相分析和红外光谱分析。通过对锰矿石中锰矿类型与氧化还原界面关系的探讨,提出了由海平面变化引起的氧化还原界面波动所控制的沉积型锰矿的成矿模式。

| Abstract: | The Dounan manganese deposit is a large-size sedimentary manganese deposit in southeastern Yunnan,and a study of its genesis can reveal the model of sedimentary manganese deposits in southeastern Yunnan.Samples from the Dounan manganese deposit were systematically studied by means of manganese phase analysis and IR spectroscopy.Based on a study of the relationship between the type of manganese and redox interface,the authors hold that the model of sedimentary manganese deposits is controlled by redox interf... |
