摘要
本文以通化二密斑岩型铜矿为例,初步探讨了应用地球化学异常进行定量预测的可行性。将二密斑岩型铜矿为典型矿床,优选相似度较高的最小预测区,同时考虑矿床的剥蚀程度,应用类比法和面金属量法,分别进行铜的资源量估算。应用地球化学异常数据进行定量预测目前存在许多问题,此次仅是初步探讨,也为深层次挖掘地球化学数据的找矿意义提供借鉴。
In this paper,the author aimed at preliminary study on the feasibility of applying geochemical anomalies to a quantitative prediction.Take the Ermi porphyry copper deposit,which in Tonghua,as a typical deposit;give preference to the smallest evaluation area,which has high similarity with Ermi Cu deposit,and considering the degree of ore deposit denudation.Apply the analogy method and the areal productivity method to estimate the copper resources.At present,there are many problems in quantitative prediction of geochemical anomaly data.This is only a preliminary discussion,and it can also provide a reference for the depth of the geochemical data on mineral exploration.
