| 摘 要： | 针对目前矿业勘探开发中的资源潜力快速评价问题,以基于GIS的数据驱动模型证据权重法为主导,结合基础地质资料,从遥感影像中提取相关构造、矿化及蚀变信息.采用中上寒武-奥陶统、义县组、雾迷山组、燕山期花岗岩、粘土蚀变、二价铁强度、三价铁强度和构造强度等8个因子评价辽西钼-多金属矿床,并通过X2独立性检验证明其在数学上的可行性,且在3大矿集区符合的基础上,评价预测出高家岭、红崖子两个成矿远景区.

| Abstract: | Based on the GIS-data-driven model in combination with the weights of evidence and basic geological data,the information on the relevant structure,alteration and mineralization can be extracted from remote sensing images to evaluate the resource potential quickly.The Mo-polymetallic deposit in West Liaoning were thus evaluated with 8 factors,i.e.,the upper Cambrian-Ordovician,Yixian formation,Wumishan formation,Yanshan-period granite,alteration of clay,intensity of Fe2+,intensity of Fe3+ and tectonic intens... |
