| 摘 要： | 本文以湖南花垣民乐锰矿床为例,研究了矿床中火山碎屑物质的分布及特征,用硫同位素氧、碳同位素等成因地球化学特征阐明该区裂陷盆槽盆或地堑盆地中海底火山喷发对锰矿形成的重要意义,并提出了成矿模式,认为湘西北锰矿床属离火山喷发中心较远的海底火山喷发-沉积锰矿床。

| Abstract: | The present paper deals with the distribution and features of the volcaniclastics from the Minle manganese deposit in Huayuan,northwestern Hunan,and the important effects of the submarine volcanic eruption on the formation of the manganes deposits in rift basins and graben basins.The mineralization model presented in this study shows that the manganese deposits in northwestern Hunan are assigned to the submarine volcanic eruption-sedimentary manganese deposits far from the centers of volcanic eruption. |
