Detection of concealed ore bodies in Jiajika rare metal orefield using geogas prospecting technology

Abstract

Abstract

An experimental research was conducted on two concealed deposits, X03 and Shaotangou, in Jiajika rare metal orefield. The geogas was collected by an air sampler, and the particles in the gas were captured by 5% dilute nitric acid solution. The results show that continuous anomalies of Li, Be, Rb, Cs, Na and B are observed from the two deposits, and can be used to explore the ore bodies 30-100 m below the earth surface. On Line 35 of X03 ore body, there is no correlation between the content of the mineral elements in the geogas and its total content in the soil. This indicates that the anomalies are formed by the elements in the geogas, not in the soil. Hence, the mineralization information is included in the geogas. The anomalies of the elements in the geogas show in top halos, located over the concealed deposits. Based on the study of metallogenic geological conditions and geophysical data, such as electrical method, drilling engineering can be arranged above the anomalies of elements in geogas for drilling verification.
