【摘要】 大冶铁矿是国家大型矿山之一,目前处于资源危机阶段。通过对大冶铁矿的接触带形态、Fe、Cu品位变化以及高精度磁法测量的研究,认为在接触带转折部位,与磁法测量成果的解释吻合较好的地段是成矿有利地段,而且根据铜铁品位等直线图可以得出沿接触带由磁铁矿向东逐渐过渡为硫化矿的结论,并且在生产实践中得到验证。更多还原

【Abstract】 The Daye iron ore deposits is one of national large-scale mines,which is at the resources crisis stage at present.Through studying on contact zone shape,change of Fe and Cu grade,as well as the high accuracy magnetometer survey,thinks the zone to conform to the result of the magnetometer survey is the advantageous mineral zone.The line graphs of Fe and Cu grade show that magnetite changes into pyrite from the west to east of contact zone,and obtains success in practice.更多还原
