| 摘 要： | 不同岩性的岩石,其放射性元素U、Th和K的含量不同,即使是同一岩性的岩石,由于成因不同,形成年代不同,地质演化过程不同,其放射性元素含量也不同.笔者根据放射性元素在岩石中分布的这个特点,利用航空伽马能谱测量数据,采用多元统计分析方法,对航空伽马能谱测量数据进行分析,并作出动态聚类图,然后再与已有的地质图对比,分析各种岩性放射性元素U、Th和K的含量,为该地区进行下一步地质工作提供依据.

| Abstract: | Different lithological rocks have different content of radio-elements such as uranium , thorium and potassium. Even if they are the same lithological rocks, as a result of different cases and age of formation, different geological evolvement process, their content of radio-elements also is different . According to this character of radio-elements in rocks , using airborne gamma-ray spectrometric data , using the statistical multi-analysis methods , this paper analyzes airborne gamma-ray spectrometric data , makes out dynamic cluster chart, compares with geological map, compartmentalizes geological element, then offers some gist for the next geological work in this area. |

| Keywords: | airborne gamma-ray spectrometry variation coefficient principal component analysis dynamic cluster |
