对采自比哈尔邦辛格布哈姆的朱布拉托拉(Jublatola)钻孔中全岩样品进行的天然热释光(NTL)研究表明:不同类型的岩石(如石英岩和片岩)发光峰的温度有显著差别,按照这一特点可划分出大的岩石类型。根据不同组分的矿物在含量上的差异,即使在同一主岩类型(如片岩)中,由于其发光峰温度的明显差别,要对其进行再分类也是可能的。在一定类型的岩石中,已知放射层范围内NTL强度的显著增加,可作为圈定放射性矿体的一种辅助方法。由未知矿体观测到的这种明显结果可解释为附近有潜在铀源,但尚未被钻孔揭露到。因而,这种方法就显示了其在铀矿勘查中的重要作用。
Natural thermoluminescence (NTL) studies of whole rock samples from Jublatola boreholes collected from Singh Buhram, Bihar, show that luminescence peaks of different types of rocks, such as quartzite and schist There are significant differences in temperature, according to this feature can be divided into large rock types. According to the difference in content of minerals of different components, even in the same host rock type (such as schist), it is possible to reclassify them due to the significant difference in their luminescence peak temperatures. In certain types of rock, a significant increase in NTL intensity within the radioactive layer is known to serve as an adjunct to delineating radioactive ore bodies. This apparent result, observed by unknown ore bodies, can be interpreted as a potential source of uranium nearby but has not yet been exposed by drilling. Therefore, this method shows its important role in uranium exploration.
