地面伽玛能谱测量在稀土矿勘查中的应用——以山东省兰陵县龙宝山稀土矿为例

Application of Gamma Energy Spectrum in Rare Earth Deposit Exploration——Settting Longbaoshan Rare Earth Deposit in Lanling County in Shandong Province as an Example

摘要:

龙宝山稀土矿是在查证该区航放异常时发现的，通过进一步开展地面γ能谱测量，在龙宝山地区圈定了3处综合放射性异常，进一步缩小了稀土找矿靶区。通过异常查证，发现3个新矿体，取得了较好的稀土矿找矿效果。本文通过分析γ能谱测量在龙宝山稀土矿勘查中的应用，为该区稀土矿的勘查指明了方向，同时分析了该区的找矿前景，为在龙宝山和周边类似地区开展稀土矿勘查提供借鉴。

Abstract:

Longbaoshan rare earth deposit was discovered during the verification of the airborne emission anomaly in the area. Through carrying out further ground γ energy spectrum measurement, three comprehensive radioactive anomalies have been delineated in Longbaoshan area, which has narrowed the target area of rare earth prospecting furthurly. Through abnormal verification, three new ore bodies have been found, and good effect of rare earth ore prospecting has been gained. Through analysis on the application of gamma spectrometry in Longbaoshan area, the direction of rare earth ore exploration in the area has been pointed out, the prospect of prospecting in this region have been analyzed at the same time. It will provide references for carrying out rare earth exploration in Long baoshan and surrounding areas.
