摘要
下院子锰矿产于南华系下统大塘坡组第一段下部,冷水溪犁式正断层(F1)的上盘,矿体呈层状、似层状缓倾斜顺层产出。文章通过对下院子锰矿系统的研究,对本区锰矿提出以下找矿标志:地层标志(大塘坡一段碳质页岩);含锰岩系厚度标志(>17 m);沉积相标志(成锰盆地);两界河组的厚度和岩性组合关系(厚度大,岩性组合复杂);构造标志(古断裂);地化标志(Mn/Cr≈40)。
Xiayuanzi manganese ore occurs in the first section of the Datangpo group under Nanhua system,hanging wall of lengshuixi F1 plow normal fault,the orebody occurs in the stratified or stratoid shape.Based on the study of Xiayuanzi manganese ore system, this paper put forward the following prospecting indicators: stratigraphic mark (shale in the first section of the Datangpo group ; Mn Rock series thickness mark ( 〉17 m ) ; sedimentary facies mark ( Manganese Basin ) ; thickness and lithology combination between the two groups (border thickness, lithology complex ) ; structure marks (paleo-fault) ; localization signs ( Mn/Cr = 40).
