    摘要:

    奇异性指数分析方法可以用于地球化学局部异常的圈定和奇异性程度的度量,其具有尺度不变性和自相似性的特征,使之能够对覆盖区地球化学弱异常信息进行有效的提取。本文在总结了奇异性指数理论基本原理的基础上,以赤湖-三岔口地区地球化学数据为例,对该区铜元素进行奇异性指数填图,并对奇异性指数填图法与传统异常填图法进行对比分析,结果显示奇异性指数能够有效的在覆盖区提取地球化学元素弱异常信息。

    Abstract:

    The singularity indices can be used to identifyregional geochemical anomalies and quantifies the degree of singularity. Because of its property of Scale invariance and self-similarity, the singularity indices analysis playedSan importantSroleSinSgeo-anomalies extraction in covered area. The basic principles and method of singularity indices are introduced in this paper by a case study of Cu geochemical-anomaly identification in ChiHu-Sanchakou area in Eastern Tianshan. AScomparativeSanalysis between traditionalSanomalies mapping method and singularity indices mapping method wasSalso carriedSout in this paper. The results show that the singularity indices analysis is effective for weak geochemical anomalies identification in covered area.
