摘要
本文通过福建政和地区矿产资源调查项目中仙岩地区开展的1:1万土壤地球化学测量工作,对仙岩地区8种微量元素进行地球化学统计分析,得出金、银、铜、铅、锌元素具较强变异系数。通过相关分析确立了测区内元素组合特征,圈定了2个Au-Ag-Pb-Zn-Cu元素综合异常区作为找矿靶区,为该区找金多金属矿提供了理论依据。通过槽探工程验证,发现6个金多金属矿矿体,初步分析了成矿模式,得出仙岩地区具有较好的找矿前景。
Based on the 1:10000 soil geochemical survey carried out in Xianyan area of the mineral resources investigation project in Zhenghe District,Fujian Province,this paper makes a geochemical statistical analysis of 8 trace elements in Xianyan area,and concludes that the elements of gold,silver,copper,lead and zinc have a strong coefficient of variation.Through correlation analysis,the element combination characteristics in the survey area are established,and two Au Ag Pb Zn Cu element comprehensive anomaly areas are delineated as prospecting targets,which provides a theoretical basis for prospecting gold polymetallic deposits in this area.Through the verification of trenching engineering,six gold polymetallic ore bodies are found,and the metallogenic model is preliminarily analyzed.It is concluded that Xianyan area has a good prospecting prospect.
