砂岩型铀矿地表物探测量的模糊聚类分析

利用地球物理异常显示参数表示剖面数据,以剖面数学期望、方差、特征峰间距、特征峰半极值为信息参数,对放射性测量剖面进行模糊聚类分析。该方法可有效区分成矿模式间的差异,对同一地区的分析表明,具有相近埋深和规模的剖面具有最强的相似性,有矿模式间具有较强的一致性,有矿与无矿剖面有较大的差异,而无矿剖面间一致性差。经新疆和内蒙等地区实测资料的解释和检验,说明这些方法用于解释异常,可以取得较好的地质效果。

Data of Surface Geophysical Exploration for Sandstone-Type Uranium Deposit Analyzed by Fuzzy Cluster Method

In this paper,a fuzzy clustering analyzed method was introduced.Data expectation,standard deviation,the space between the especially apices,the distance of especially poles and the width of the half especially poles of section data define as factor of this method.The section data use IGA parameter.The method is able to distinguish between the difference deposit models.In same district,it is said that the sections with analogy depth and range are most analogy.The sections containing deposits have more analogy.The sections containing deposits and not containing deposits have more difference.The sections without ore body have more difference.If the class has a section which was explored before,we can generalize the character of this section to others.If all section of the class were unknown,we can use the classed information to introduce the next works.
