| 摘 要： | 本文以新疆某1∶50 000化探数据为例,运用累频法、均值标准差法、以及面积-周长(C-A)分形方法计算研究区主要成矿元素Cu异常下限值,并运用不同的异常下限值圈定了铜的地球化学异常,并对不同方法进行了对比分析,实践表明,分形法确定的异常下限更适合于本研究区。

| Abstract: | Taking 1∶50 000 geochemical exploration data of a copper ore deposit in Xinjiang as example,the Total Frequency Method,Average Value Standard Difference Method,and Area-Perimeter(C-A)Fractal Method are used to calculate the abnormity lower-limit value of the main mineralization element(copper)of the deposit.Different abnormity lower-limit values are used to define geochemical abnormities of copper.Different methods are compared.The practice shows the abnormity lower-limit value determined through Fractal Method is most suitable for the deposit. |

| Keywords: | copper ore deposit abnormity lower-limit Fractal Method Average Value Standard Difference |
