山东省海阳市下十字夼地区土壤地球化学异常特征及找矿前景分析

Characteristics of soil geochemical anomalies in xiashizikuang area,Haiyang City, Shandong Province and Analysis of ore prospecting prospect

海阳市下十字夼地区位于胶莱盆地东北缘,探讨该地区金矿的化探异常特征及找矿前景,对在胶莱盆地东北缘地区寻找金矿具有重要指导意义。在下十字夼地区开展了1/1万土壤地球化学测量,显示Au为富集元素。在研究区圈定4个土壤综合异常,选择异常较好的AS2异常区开展了查证工作,发现1条金矿化体。结合成矿地质条件,初步建立了地质、地球化学和构造等方面的找矿标志,探讨了矿床成因,指出今后找矿方向。

Xiashizikuang area of Haiyang City is located in the northeast margin of Jiaolai basin.It is of great significance to explore the geochemical anomaly characteristics and prospecting prospects of gold deposits in the northeast margin of Jiaolai basin.1/10000 soil geochemical survey was carried out in xiashizikuang area.It shows that Au is an enriched element.Four soil comprehensive anomalies were delineated in the study area The AS2 anomaly area with good anomaly was selected to carry out anomaly verification,and a gold mineralized body was found.Combined with metallogenic geological conditions,The prospecting criteria of geology,geochemistry and structure are preliminarily established,the genesis of the deposit is discussed,and the prospecting direction in the future is pointed out.
