摘要
"桃江式"锰矿系指赋存于湘中地区奥陶系中统磨刀溪组下部页岩中的优质碳酸锰矿。该区奥陶系地层发育,碳酸锰矿体仅赋存于局部奥陶系地层中,其空间分布范围、形态、规模等与构造有关,古构造控制了成锰盆地,同生断裂控制了锰矿体分布形态及规模,成矿后构造又使矿体空间分布发生改变,研究"桃江式"锰矿地质构造特征对在该区开展优质锰矿找矿勘查工作,具有现实的指导意义。
Taojiang-style' manganese deposits are referred to high quality manganese carbonate ores in Modaoxi formation shale of middle Ordovician in the central Hunan province. Ordovician strata are well developed in the region, and manganese carbonate ores are only distributed at local Ordovician strata. Spatial distribution extents, shapes and scales of the ores are related structure. Paleo-structures controlled manganese-forming basin, and syngenetic-faults governed distribution extents and shapes of manganese ores. Post-mineralization structures changed spatial distribution of the ores. Researches on geology-structure characters of manganese deposits are actually helpful for prospecting of high quality manganese carbonate ores in the regions.
