摘    要:为了尽快突破第四纪厚层沉积物覆盖区找矿难题,在安徽凤阳开展了地电化学方法技术找矿可行性研究,即采用低电压(9 V)偶极地电提取与土壤离子电导率测量组合方法开展找矿工作。结果表明,在隐伏金矿体上方出现明显的电化学异常。据此,在南部隆起地段发现了1处找矿有利部位,并提出深部找矿工作建议。经后期钻探工程验证,发现1个品位为2 g/t金矿体、2个金矿化体。

关 键 词:地电化学法  隐伏金矿  第四系  厚层覆盖区  凤阳  安徽

Abstract:For prospecting the buried deposit in the huge covered sediment region formed during the Quaternary period as soon as possible,it is necessary to use geoelectro-chemical method to inspect the available gold deposit under the huge coverage of alluvium in Fengyang Anhui province.Methods include geoelectrio-chemical extraction technique to get the icon information with both electrode in low-voltage(9 V),and to measure icon conductance in the surface soil.It is verified that the geoelectro-chemical abnomaly found buried gold deposit.So a swell zone in the south field for seeking buried ore bodies is selected,and a prospecting area gold deposit is found.One ore body(average grade 2 g/t)and two mineralized body(average grade2 g/t) are found in the testing drilling.
Keywords:geoelectro-chemical method  hidden gold deposits  Quaternary  huge coverage of alluvium  Fengyang  Anhui
