物探方法在大兴安岭北部782高地铌钽矿床找矿中的应用OA
Application of geophysical methods in the exploration of Nb-Ta deposit in No.782 Highland,northern Daxinganling Mountains
黑龙江省漠河市782高地铌钽矿床是近些年来在黑龙江省发现的唯一达到中型矿床规模的稀有金属矿床,矿床伴生有稀土(富钇)、锆、铀等,潜在价值巨大.该矿床是在地面伽玛能谱查证航空放射性异常基础上发现的.地面伽玛能谱异常与成矿地质体对应明显,显示了物探方法对于寻找该类型矿床的有效性.伽玛测井放射性曲线对于矿体的对比连接具有重要的指示意义,能够有效指导野外样品采取.放射性测量与伽玛测井工作对此类矿床勘查找矿具有重要的指导意义.
The No.782 Highland Nb-Ta deposit in Mohe City is the only medium-scale rare metal deposit discovered in Heilongjiang Province in recent years.The deposit is associated with rare earth elements(Y-rich),Zr,U,and other components,and thus has significant potential value.This deposit was found through the verification of airborne radiometric anomalies by ground gamma-ray spectrometry.The ground gamma-ray spectrometry anomalies correspond well with the ore-forming geological bodies,demonstrating the effectiveness of geophysical methods in exploring this deposit type.Gamma-ray logging curves play a significant role in the correlation and connection of ore bodies and can effectively guide field sampling.Radiometric surveys and gamma-ray logging are therefore of great significance for the prospecting of such deposits.
