| 摘 要： | 峪耳崖金矿是冀东幔枝构造外国主折离带上盘盖层中，受反向铲状断层和次级折离带共同控制的典型金矿。突出表现为复合构造控制燕山花岗质岩体呈塔状展布，而次级折离带的持续折离滑脱使成岩后的岩床状花岗岩产生一系列缓倾裂隙，并成为主成矿期的主要储矿构造扩容带。文中探讨了冀东是区地质演化过程，分析了区域成矿构造特征，总结了成矿作用机理，归纳了成矿模式。认为深部找矿仍有较大远景。

| Abstract: | The Yuerya gold deposit is a typical deposit in the hanging wall of the main detachment belt around East Hebei mantle branch. The gold deposit is controlled by antithetic listric faults and subsidiary detachment belts. Yanshanian granite bodies controlled by complex structures are characterized by tower-like distribution. Owing to successive activities of the subsidiary detachment belts,postdiagenetic granitic sill formed a series of low-angle fractures, which became the main structural expanding and ore-hosting belt in the major mineralization period. Geological evolutionary process and regional ore-forming structural characteristics are discuissed in this paper. On the basis of detailed studies, the ore-forming mechanism and the metallogenic mechanism are summarized. It is considered that fine ore-hunting prospects remain existent at depth. |
