【摘要】 采用数字图像增强技术,对遥感影像进行增强处理,提取控矿构造和地层信息;运用比值逻辑乘运算提取混合矿化蚀变信息;结合控矿构造和地层信息,选择三者吻合度较好的区域,圈定了矿化蚀变异常区域.野外调查证实,部分蚀变异常区与铁矿采区吻合较好,并见多处含金矿化石英细脉.更多还原

【Abstract】 The ore-controlling structure and ore-bearing stratum information is extracted by digital image enhancement processing. The information of mixed alteration anomaly is extracted with ratio logistic multiplication. The anomalous zones for mineralized alteration are delineated by the combination of the three kinds of information. Field investigation has proved that some of the alteration anomaly zones are in accord with iron diggings and a few gold-bearing mineralization quartz veins.更多还原
