摘要
崔家金矿是山东地区近年来发现的一个重要的金矿床,该矿主要分布在招莱金矿带灵北-双目顶断裂北东段区域上,目前该区已有16条矿脉被发现,其中主要的工业矿体为1号、10号、13号。文中对该矿区域地质特征进行分析探讨,认为金矿成矿过程中初始的矿源层、构造以及载矿热源体起着重要的控矿作用。围岩蚀变在区域上比较发育,主要包括绢云母化与黄铁矿化与硅化,这些围岩蚀变和区内金矿成矿有着非常紧密的关联性。结合矿床产出以及时空分布规律,崔家金矿成因类型为中温热液交代充填行金矿床。基于以上研究和分析,优选出找矿靶区四个,特别是1号和10号矿脉外围和深部有中型金矿找矿前景,应当进一步扩大找矿研究工作。
Cuijia gold deposit is an important gold deposit discovered in recent years in Shandong Province.It is mainly distributed in the northeast section of Lingbei shuangmuding fault in Zhaolai gold belt.At present,16 ore veins have been found in this area,among which the main industrial ore bodies are No.1,No.10 and No.13.Based on the analysis of the regional geological characteristics of the deposit,it is considered that the initial ore source bed,structure and ore bearing heat source body play an important role in the ore-forming process.Wall rock alteration is relatively developed in the region,mainly including sericitization,pyritization and silicification.These wall rock alterations are closely related to gold mineralization in the region.Combined with the occurrence and temporal and spatial distribution of the deposit,the genetic type of Cuijia gold deposit is mesothermal metasomatic filling gold deposit.Based on the above research and analysis,four prospecting targets have been selected.Especially,there are medium-sized gold prospecting prospects in the periphery and deep part of No.1 and No.10 ore veins,so the prospecting research work should be further expanded.
