| 摘 要： | 东党铝土矿赋存于中石炭统本溪组(C2b),其分布在早古生代的边缘,构造环境相对稳定沉积间断时间长,沉积相为泻湖-沼泽相,下伏地层为中奥陶统马家沟组灰岩,成矿条件表明,该区有一定的找矿前景。区内构造简单,古岩溶洼斗对成矿有利,矿体呈似层状、透镜状、漏斗状。

| Abstract: | Dongdang alum clay resides in the Middle Carboniferous Benxi Formation(C2b) and can always be found on the border of the early Paleozoic system,where the structural setting is pediocratic,non-sequence is long,sedimentary context is lagoon-swamp,underlying formation is Middle Ordovician Majiagou formation limestone.There's a certain prospecting ore based on the analysis of the mineral-formation condition.The structure of this area is simple and the Fossil karst embrasure cavity is benefit for miner formation.The shape of the mineral ore are stratoid,lensing and funnel. |
