| 摘 要： | 遥感技术能以较低的成本快速地提供更多更有效的地质异常信息,在分析云南省鹤庆北衙金矿的区域地质背景和控矿规律的基础上,通过目视解译的方法对该区的线性构造和环形构造进行了解译,并利用MORPAS软件对其进行详细的定量分析,绘制了线环构造等密度和优益度的等值线图。并分析蚀变异常的光谱反映特征,提出增强铁化和硅化蚀变异常的方法,从ETM影像中利用比值和主成份分析的方法提取与金矿有关的铁化、硅化蚀变异常信息,解译效果良好,最后综合分析圈定出三处最有利的找矿远景区。

| Abstract: | The remote sensing technology,has been used to prospect ore,armed to provide more accurate mineralization abnormal information and decrease the exploration risks extremely.Based on the region geological background and the controlling rules of fault in Heqing,the linear and circular fault structures are examined with visual interpretation from remotely sensed data.The isopycnal map and the excellent benefits image are drawn and analyzed quantitatively with MORPAS.Then the alternation characteristics are analyzed.The Fe2+/3+ and Si2+ alternation information related to gold deposits is extracted with band math and principal component analysis,the results of the extraction are very well.The three favorable prospected areas are delineated with synthesizing controlling factor of ore deposits. |
