Determination of Metal Elements Thresholds in Soil with Fractal Method-A Case of Cu in Daxing Area,Hefei
分形方法确定土壤中重金属异常下限——以合肥大兴地区Cu元素为例
The calculating methods of geochemical anomaly thresholds are very important in mineral exploration and resource prediction.
化探异常下限计算方法在矿产勘查和资源预测中非常重要。
For a long time, the threshold is confirmed on the assumption that the concentration of chemical elements in the crust follows a normal distribution or concentration of elements takes on a continuous change in space.
首先利用含量-面积的分形方法得出该地区金元素的异常下限,做出金元素异常分布图,然后与已有的山东地区金矿的分布图进行叠加分析,发现金矿的分布范围集中在用含量-面积的分形方法确定的金元素的高异常区域,因此可以根据分形确定的异常区来预测潜在的金矿区。
