Abstract

Abstract

The correlation between content assemblage of radionuclides in ores and ore content of rock is analyzed to guide the exploration of lithium-beryllium rare earth ore resources. The granite pegmatite dikes in Chakabeishan area are measured for magnetic and radioactive characteristics by using ENVI Pro proton magnetometer and ARD multichannel gamma-ray spectrometer, to determine the content distribution rule and anomaly location of ²³⁸U, ²³²Th and ⁴⁰K, delineate ore-bearing rock bodies, extract information and analyze the correlation between magnetic anomaly and radioactive element content. The results show that the background field with high U, Th and K in the north anomaly area is mainly controlled by epimetamorphic rocks originated from sedimentary rocks. In the middle and southern anomaly areas, the area near the joint of two veins and contact zone where the magnetic anomalies overlap U-Th mixed anomalies have the greatest potential for rare metal and rare earth ores exploration, reflecting that the correlation analysis of magnetic survey and energy spectrum measurement can provide a good geophysical basis for future prospecting.
