Detection of concealed ore bodies in Jiajika rare metal orefield using geogas prospecting technology
-
摘要: 以甲基卡稀有金属矿区X03号矿体和烧炭沟矿体2个隐伏矿体作为研究对象，采用主动吸气法，以5%稀硝酸溶液作为捕集剂进行地气测量试验研究。结果表明，地气捕集液中Li、Be、Rb、Cs、Na、B等元素在矿体上方出现多点连续的组合异常，可以指示地表以下30~100 m的隐伏矿体。X03号矿体35号勘探线上，地气中成矿元素异常与土壤中元素含量之间没有相关性，表明地气异常并不是土壤元素含量所形成的，而是来源于隐伏矿体，是隐伏矿体的直接信息反映。地气异常表现为顶部异常特征，隐伏矿体位于异常的下部。甲基卡稀有金属矿区采用地气测量技术寻找隐伏矿体时，在成矿地质条件研究的基础上，结合电法等地球物理资料，可在地气异常的上方布置钻探工程进行钻探验证。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.
