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。
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.
