异常块体中金属资源量的计算方法初探

Study of calculative method for metal reserve in anomalous block

为了将区域化探异常的找矿意义作出定量化的评价,在前人研究的基础上,提出了区域化探异常块体中的金属资源量的计算方法与计算公式,其中选择了剩余异常值(M)作为计算异常块体内富集金属量的重要参数,提高了预测的准确性,初步实现了预测资源量从定性向定量化的转变。经已知矿产地异常块体的金属资源量的计算验证,效果令人满意。

On the basis of previous research,the authors put forward the method and formula to calculate the metallic resource reserve in regional geochemical exploratory anomalous blocks in order to quantitatively evaluate the prospecting significance of the anomalies,in which the surplus anomalous value is selected to be important parameter for calculating the enriched metallic reserve in anomalous block and improves the accuracy of prognostic. It is preliminarily realized the change of calculating the resource reserve from the qualitative to the quantitative. The efffct is satisfying through the test and verification of calculating the metallic reserve of anomalous block in known mine fields.
