摘　　要：在马脑壳金矿外围某金矿勘查区,研究了已知金矿体上方的X荧光异常特征。通过现场土壤多元素X荧光测量,快速捕获了4个As、Cu、Pb、Zn、Sr综合异常。根据矿异常的特征分析,确认了这些异常的性质,确定了两处新的金矿找矿靶位。对找矿靶位内的土壤取样做Au定量分析,绝大部分样品的金含量都远高于测区背景值,最高Au品位比测区背景值高100多倍。可以确认,找矿靶位处的X荧光异常确实为金矿所引起。Characteristics of the XRF anomalies above the periphery of the Manaoke Gold Mine. By multi-element known golden ore body have been studied in the XRF measurement in-situ in soil, four As,Cu, Pb,Zn,Sr composite anomalies have acquired rapidly. On the basis of Characteristics of the XRF anomalies, the nature of the all of the XRF anomalies have been affirmed, and the two new target areas of golden exploration have been defined. Be analysis of the sampled soil in the new target areas, it is indicated that the golden content of great majority of soil samples are above the background. The highest golden content is 290×10^-9 , and is more 100 times than the background. It is indicated incontestably that the XRF anomalies in new target areas are the anomalies of golden ore body.
