| 摘 要： | 应用薄片物源分析技术和石英阴极发光技术，对采自越北古陆北缘斗南和汤得地区含锰岩系法郎组砂砾岩样品进行分析，追踪陆源碎屑源区，判别锰质来源的岩性和层位：越北古陆北缘法郎组地层中的锰质主要来源于越北古陆泥盆系含锰硅质层。阴极发光特征反映最初物源区的母岩特征。

| Abstract: | The source analysis of section and quartz cathodoluminescence are applied to analyze the Falang Formation psepyolite samples of Mn - bearing rock series in Dounan and Tangde area of north margin of N Viet Nam Old Land. The source of terrigenous clastics is traced and the lithological character and horizon of Mn source are discriminated. The results show： the Mn in Falang Formation of north margin of N Viet Nam Old Land results mainly from the Devonian Mn - bearing siliceous bed in N Viet Nam Old Land. The cathodoluminescence characteristics reflect the mother rock＇ s characteristics of the most primitive origin area. |
