本文着重介绍铀同位素比值法在灰岩地区,砂岩地区和花岗岩地区试验的三个例子。初步说明方法可用于区分矿与非矿异常,初步归纳了在灰岩地区铀矿化异常表现为低值异常,而花岗岩地区和砂岩地区则相反,矿化异常表现为高值异常。 This article highlights three examples of uranium isotope ratio testing in the limestone, sandstone and granite regions. Preliminary description of the method can be used to distinguish between ore and non-mine anomalies, initially summarized in the limestone area uranium mineralization anomalies showed low anomalies, while the granite and sandstone areas on the contrary, abnormal mineralization showed high anomalies.
