土壤测量样品处理方法对金异常圈定的影响与应用——以湘东北棉花坡矿区为例
Influence of the Processing Method in Soil Survey on Determination of Gold Anomalies and Application:An Example of the Mianhuapo Mining Area in Northeast Hunan
摘要
Abstract
In prospecting and detailed investigation of geological exploration work,the indicating role of soil geochemistry is one of the important decisive factors.With the development of surface and shallow minerals,it is increasinglu difficult to prospect deep blind ore-bodies.According to the currently processing methods and technical requirements of soil samples,the analysis data of soil survey in mineralization sections of the gold mining area are weakened and the lower limit values of element anomalies are on the low side.In order to salve the problem in anomaly determination from anomaly depletion,this work attempts to improve and adjust the processing method of soil samples.For the first time,it is proposed to finely divide samples from the field,after drying without sieving processing.This method has been applied to the ore search in the Mianhuapo gold mine of Liling city,Northeast Hunan.The results of the test and the content curves were analyzed.The comparison shows that the non-sieving processing samples can better reflect the anomalies of Au element in the mining area.It can help guide ore search,and achieve good results.Therefore,this test has some reference meaning for sample processing in soil survey in similar gold mining areas.关键词
