小秦岭地区地质构造格架为新太古界片麻岩穹窿，燕山期岩浆活动强烈，为岩浆热液型金矿密集分布区。金矿床的成矿与赋存与石英脉和蚀变糜棱岩的分布位置密切相关，在ETM+遥感图像中多表现为线性、平行线性密集带等韧性、韧-脆性剪切带构造特征。因此，开展小秦岭地区遥感线性构造、特别是线性构造密集带分布特征研究对该地区金矿找矿预测具有重要的指导意义。基于以上认识，以ETM+图像为基础图像，对小秦岭地区线性构造密集带和燕山期环形构造进行遥感解译，分析了该地区金矿床(点)的分布位置、成矿背景和找矿规律，编制了该地区金矿成矿遥感特征条件有利度图，进行了该地区金矿的遥感找矿预测，为河南省矿产资源潜力评价中的小秦岭地区金矿找矿工作提供了参考依据。

Xiaoginling region has densely - distributed magama hydrothermal gold deposits. The structural framework in this region is the Neoarchean gneiss dome,where intense magmatic activities occurred in Yanshanian period. The gold deposits are closely related to the distribution of quartz veins and altered mylonite. In the ETM+remote sensing image,the deposits often find expression in linear, parallel linear intensive belts and flexible-brittle shear zones. Consequently, the distribution of remote sensing linear structures and the intensive belts of linear structures are very significant for the gold ore prediction in this region. On such a basis and with the ETM+ remote sensing image as the basic map,the authors made interpretation of the linear structure intensive belts and circular structure of Yanshanian granite bodies in Xiaoginling region. The gold deposit distribution and metallogenic regularity were analyzed based on remote sensing interpretation, the maps showing the favorableness of the metallogenic remote sensing characteristic conditions for gold deposits in this region were compiled, and the remote sensing prospecting prediction of gold resources in this region was made. These results will provide some reference for the prospecting of gold deposits in Xiaoqinling region and the assessment of mineral resource potential in Henan Province.
