| 摘 要： | 丰宁县北部有大面积燕山期火山岩分布,通过航磁及物化探资料综合分析,和顺店附近存在一个隐爆火山角砾岩筒,伴随着火山—侵入活动,火山口附近及其周围形成一系列环形断裂构造,加上区域构造运动的叠加,为深部含矿热液的运移提供了通道和储矿空间。近期的找矿实践证明,在火山构造的北部及东部已经发现了Ag、Pb、Zn多金属矿化,并有望形成具有经济价值的工业矿体,综合分析该区成矿地质条件,在火山构造的南部及西部有望实现找矿工作的新突破。

| Abstract: | Here are large-scale Yanshanian volcanic rocks distributed in Fengning area.Based on a comprehensive analysis of aeromagnetic,geophysical and geochemical data,the authors have found that there exists a concealed eruption breccia pipe around Heshundian area.Accompanied by volcanic-intrusive activities,a series of annular fault structures were formed in the vicinity of or around the crater.These structures provided ore-forming channels and space for deep ore-bearing hydrothermal fluids in association with the... |
