| 摘 要： | 通过对遥感图像的解译研究,金厂峪地区发育有一系列的环形影像特征。在重、磁资料上也有明显的环形异常。它们的成因有三类:太古宙变质上壳岩中的环形构造;古褶曲构造;岩浆侵位形成的环形构造。通过对它们的影像特征和地质特征的研究,总结出本区太古宙基底岩系发育有近东西向的古褶曲构造,它控制了后期的岩浆侵位和盖层沉积。而岩浆侵位与本区金矿床的分布有密切关系,因此本区环形构造的研究有着重要的地质意义。

| Abstract: | Tis paper, basd on interpretalion and analysis of remate sensing image. The area of Jin changyu have a lot of circular shape on remote sensing image. The arcomagnitic and areogravitic abnonmal features of this area also show a clearly circular characteristics. The orign can be divided into three types: there are circalar tectosome in Archaean gneiss oval tectonic area, fold and magmatism from circalar structure. Arcuate fold of double - layer deck texture is the most fundamental tectonic framework which controls the development of linear feature and magmatic enplacement in this area. Distribution of gold deposits relate to circular structure which are formed by magmatic emplacement. Gold deposits of ten range over 6 km of the cxteral belt of circulal structare, for example, Jin changyu gold deposit lies to 2 km of Qing shan kou circular structure. |
