杨立掌锰矿赋矿层位于扬子陆块东南部被动边缘褶冲带铜仁逆冲带的半局限浅海盆地中,含矿层位(含锰岩系)为南华系下统大塘坡组第一段下部,炭质页岩、粘土岩,矿体呈层状、似层状,矿石矿物主要为菱锰矿、钙菱锰矿、锰方解石、锰白云石等,矿体厚度受构造及沉积环境等因素的控制,通过对矿床地质特征、岩相古地理、古构造等综合分析,推测该区具有较大的找矿潜力。
The Yangliezhao manganese ore ore deposit is located in the semi-confined shallow sea basin of the fold-thrust belt of Tongren thrust in the southeast margin of the Yangtze block. The ore-bearing strata (manganese-bearing rocks) are the lower part of the first segment of the Datangpo Formation , Carbonaceous shale and clay rock. The ore body is layered and stratified. The ore minerals are mainly rhodochrosite, calcium magnesite, manganese calcite and manganese dolomite. The thickness of ore body is controlled by the factors such as structure and sedimentary environment Through the comprehensive analysis of the geological characteristics of the deposit, lithofacies palaeogeography and paleotectonics, it is presumed that the area has a great prospecting potential.
