| 摘 要： | 辽西建平北部金矿床和矿点分布集中 ,具有利成矿条件。通过对该区TM图像的遥感地质解译 ,提取了线性构造、环形构造及韧性剪切带构造信息 ;利用波段比值及主成分分析等数字图像处理方法 ,对区内重点地段进行金矿化蚀变信息提取处理 ,蚀变异常在图像上以彩色晕圈显示。研究表明 ,区内线环构造、韧性剪切带构造及蚀变异常发育的复合部位 ,是金矿成矿的有利地段。根据对本区金矿成矿条件的综合分析 ,在区内圈出了 3处金矿成矿预测区 ,并在野外验证中发现 3处金矿点 ,取得了较好的找矿效果。

| Abstract: | The metallogenic background is advantageous for oreforming in northern Jianping Liaoning province. Based on the interpretation and analysis of TM remote sensing image and its database in Jianping district, a lot of information are extracted, which include linear structure,circular structure,ductile shear zones, altered abnormality etc.The altered abnormality is shown as color haloes in the image. The superimposition of linear structure,circular structure,ductile shear zones, altered abnormality are advantageous to the gold mineralization.According to the research of metallogenic conditions, three gold metallogenic predicting districts have been selected. Three gold spots have been found among the predicting districts which was a satisfying result. |
