| 中文摘要: |
| 广西下雷锰矿是我国目前最大的锰矿床。笔者根据该矿床的地质特征、控矿构造和矿石矿物组合等特点,认为是一个具有沉积作用、海底火山-热水沉积和风暴作用等,多因素多阶段、连续成矿的国内少有的矿床。 |
| 英文摘要: |
| Typical manganese storm deposits in Xialei, Guang Xi are composed of gravel fragment manganese ores, pisolitic or oolitic manganese ores and banded(streddy)mangganese ores etc in which abundant sedimentary structures formed in differnt stuges of storm activity are present, ① sharp basal boundary and basal surface structures such as gutter casts, pocket casts and lag gravel; ② hummoky cross stratification; ③ post-storm fossil trace. Therefore the author, in the light of the adove informations, holds that Xialei Mn-deposit is of storm origin. |
