摘要
对西藏尼龙玛地区地质概况进行简要分析,用分形方法中的含量—面积法对西藏尼龙玛地区1:5万水系沉积物数据进行分析处理,识别出局部异常,固定出了铜元素的异常分布图。与常规方法进行对比分析,评价了分形方法的应用效果。综合地质及其他资料对固定的化探异常区进行了分析,为实际勘查工作提供了指向作用。
The geological profiles of Nylon,Tibet were briefly analyzed.The 1:50000 sediment data was analyzed and proccessed using fractal methods in the content-area method.The local anomaly was recognized and the copper element anomaly distribution was delineated.Compared with conventional methods,the application effect of fractal method was evaluated.Under combination with geological and other information,the geochemical anomaly zones delineated were analyzed.The result provides important effect for the practical exploration work.
