摘要
张家营银金矿位于张北县东北部,地处华北陆块北缘中段,康保—围场深断裂与尚义—隆化深断裂所夹持的区域,地层、构造、岩浆岩“三位一体”配置齐全,成矿地质条件优越,与张北蔡家营铅锌银典型矿床具有相似性。论文以张北县张家营银金矿为研究对象,通过对其物化探特征、矿体赋存及品位变化情况的分析,研究其成矿、控矿地质条件;通过与蔡家营铅锌银矿典型矿床进行对比,进一步总结成矿规律,确定找矿标志,探讨矿床成因、成矿时代等问题,进而对其找矿前景进行评价。
Zhangjiaying Ag-Au deposit is located in the northeast part of Zhangbeicounty,mid-piece of the northern margin of north China landmass,and an area enclosed by Kangbao–Weichang deep fracture and Shangyi–Longhua deep fracture.It is perfectly integrated by stratum,structure and magmatic rock,with superior geological conditions for mineralization,which has similarity to the typical deposit containing elements like Caijiaying Pb-Zn-Ag deposit of Zhangbeicounty.The paper takes Zhangjiaying Ag-Au deposit in Zhangbeicounty as an object to study its geological conditions of mineralization and ore-controlling through the analysis of physic-chemical prospect features,ore body occurrence and ore grade.After a comparison has been made with the typical deposit containing elements like Caijiaying Pb-Zn-Ag deposit,a further regularity of mineralization is summarized to confirm indicator for deposit,discuss deposit genesis,mineralogenetic epoch and related problems,and make a deep evaluation on resource potential.
