摘要
本文对甘肃金塔县某调查区的地球化学特征进行了详细分析,并探讨了该区域的找矿前景。通过1:50000水系沉积物测量,分析了Au、As、Sb、Hg等多种元素的地球化学参数,揭示了元素的分布规律、相关性及异常特征。结合地质构造背景,对调查区进行了地球化学分区,并识别出多个具有找矿潜力的异常带。研究表明:调查区地球化学特征明显,多个元素显示出高背景和强富集特征,地层和侵入岩中多个单元富集成矿元素,综合异常分布广泛,且多个异常已通过查证发现矿化线索或矿体,调查区找矿前景较好。
In this paper,the geochemical characteristics of a survey area in Jinta County,Gansu Province are analyzed in detail,and the prospecting prospect of this area is discussed.The geochemical parameters of Au,As,Sb,Hg and other elements were analyzed by 1:50000 stream sediment survey,and the distribution,correlation and anomaly characteristics of the elements were revealed.According to the geological structure background,the investigation area was divided into geochemical zones,and several anomalous zones with prospecting potential were identified.The research shows that the geochemical characteristics of the survey area are obvious,with many elements showing high background and strong enrichment characteristics,multiple units in the strata and intrusive rocks enriching ore-forming elements,comprehensive anomalies are widely distributed,and several anomalies have been found through the investigation of mineralization clues or orebodies,and the prospecting prospect of the survey area is good.
