摘　　要：在花岗岩型铀矿床上分别采集了含矿和无矿岩石样品及含矿和无矿土壤样品,用精密热释光剂量仪测量了它们的发光曲线和发光强度,并对所测结果进行了对比分析。初步研究的结果表明:含矿和无矿岩石样品及含矿和无矿土壤样品的热释光发光特征差异明显,可以用该方法找寻花岗岩型铀矿床。Ore-bearing and barren rocks and soils were sampled in granite type uranium deposits, and their glowing curves and intensities were measured. A comparative analysis of the data indicates that the differences of glowing characteristics between ore-bearing rocks and soils and barren ones are obvious, and the soil TL survey can be used to find granite type uranium deposits.
