| 摘 要： | 河北省丰宁县坝州营金矿床赋存于五台期侵位的“变闪长岩”中，该区从太古代到中生代长期处于构造隆升剥蚀状态，发育多期岩浆侵位事件，为金矿提供了充分的成矿条件。根据区域地质背景及围岩蚀变、矿化等特征，推断本矿床属于受构造控制的中一低温热液石英脉型金矿。结合矿区地质特征开展地球物理工作，以高密度电法圈定了地下矿化体的范围，辅以音频大地电磁测量，实现探测相对深部断裂构造，并以钻探证实，取得了找矿突破，达到了推断控矿构造的走向和找矿前景等目的。

| Abstract: | Bazhouying gold deposit occurs in epidiorite which invaded in Wutai period, this area has experienced tectonic uplifting and eroding from Archean to Mesozoic and lots of magma emplacement events which provided the favorable condition for the ore-forming process. The gold mineralization is inferred to be low-mid temperature quartz-vein type controlled by faults. In this paper geophysical works is chose according to the geological character of the ore district, the range of the mineralized bodies underground are delineated by high density electrical method and the deeper parts of faults are detected by EH4 and then verified by drilling. Finally the trend of the ore-controlling structure is deduced and breakthrough prospecting result have been obtained for gold deposit. |
