闽西一带,次生富锰矿分布广泛,点多面广,为本省目前锰矿资源的主要来源.十多年来,运用激发极化法,在配合地质圈定矿化范围或直接发现盲矿体方面,均取得了较好的地质效果.地质概况锰矿体主要赋存在第四系堆积层及构造裂隙或破碎带中.其下伏基岩及围岩为中、上泥盆系至石炭-二迭系地层,有石英砂岩、石英砾岩、灰岩、页岩等.锰矿物可能来源于上古生代的一套地层.
In the western Fujian area, the secondary manganese ore is widely distributed and widely distributed, which is the main source of manganese resources in the province at present.For more than ten years, by using the excitation polarization method, in coordination with the scope of geological delineation or the direct discovery of blind ore bodies, Have achieved good geological results Geological Survey Manganese ore body mainly in the Quaternary accumulation and structural fissures or broken belt.The underlying bedrock and surrounding rock in the upper Devonian to Carboniferous - Strata, quartz sandstone, quartz conglomerate, limestone, shale, etc. Manganese minerals may be derived from a set of strata of the Upper Paleozoic.
