| 中文摘要: |
| 祁雨沟矿田内的控矿构造按形态可分为爆破角砾岩筒和断裂构造,分别控制着爆破角砾岩型金矿床和构造蚀变岩型金矿床的产出。在祁雨沟、郭庄、边庄3个爆破角砾岩筒群的北东侧,对应产出公峪、铁驴皮沟、火神庙沟3个断裂密集带,两类控矿构造在空间上相隔相望或相通,两种类型金矿床的矿化强度彼此消长。在爆破角砾岩群内存在矿化中心,自中心向四周矿化逐渐减弱。因此,研究该区金矿成矿规律或开展找矿潜力评价,应着重研究并确定爆破角砾岩筒群中的矿化中心及爆破角砾岩筒与含矿断裂构造的连通关系。 |
| 英文摘要: |
| The Ore-controlling structures in the Qiyugou ore filed can be classified as explosive breccia pipes and fault structures according to the physical form, which controls the distribution of the explosive breccia type gold mineralization and the structural altered rock type gold mineralization respectively. Three explosive breccia pipes were identified, i.e, Qiyugou, Guozhuang and Bianzhuang pipe. In the northeast part of these pipes, three densely fault zones were formed, namely Gongyu, Tielupigou and Huoshenmiaogou. These two types of ore controlling structures are apart in space each other, and or connected each other. As a result, the intensity of these two types of gold mineralization occurs as a phenomena of “growth and decline”. In the center of the breccia pipe, gold mineralization is most intensive, and decreases outward. Therefore, to study the metallogenetic regularities or evaluate the prospecting potential for this, it should pay attention to the the mineralization within the explosive breccia pipes and the connection pass between those explosive breccia pipes and ore- bearing fault structures. |
