应用分形方法研究了新南威尔士地区地球化学异常及其下限的确定,对该区的地球化学铜元素异常区进行了圈定。通过与传统方法圈出的异常区进行比较,分形方法确定的异常下限更符合实际情况,并认为研究区域的东北部与南部存在铜矿床的可能性较大,为进一步找矿指明了方向。该方法不仅适用于地球化学铜元素数据,而且还适用于其他元素和地质数据,具有普遍的意义。
The paper studies application of geochemistry anomalies and the definition of lower threshold in New South Wales region, Australia. Compared with anomalies delineated by conventional method, threshold obtained by fractal method is more practical. It's more likely to discover Cu deposit within the north-east and southern part of the study area. The method is not only applicable to Cu but also has universal meaning for other geochemical elements or geological data.
