一、引言大面积的航空放射性γ测量通常能产生大量的航空放射性测量异常(以下简称异常)。除了航测队飞行时划分的强度较大、峰形较好的老异常外,近几年来,通过对航放资料重新整理,又分出大量强度较低、峰形较差的新异常。在这些新、老异常中,只有少数是地面已知的矿床和矿点。有一些异常进行过一定的勘探揭露。但大部分异常的地面工作程度都较差。 I. INTRODUCTION A large area of ​​aeronautical radioactivity gamma measurement can often produce a large number of aeronautical radioactivity anomalies (hereinafter referred to as anomalies). In addition to the high-intensity and peak-shaped old anomalies that were assigned to the aerial team during its flight, in recent years, a large number of new anomalies with lower intensity and poorer peak shapes were separated through the rearrangement of navigational aids. Of these new and old anomalies, only a few are known deposits and mines on the ground. There are some exceptions to conduct a certain exploration revealed. However, most of the abnormal ground work is poor.
