由于控制区与预测区缺乏成矿地质环境的数量化类比,丰度模型法用来进行矿产资源评价误差较大,且常与实际情况不符。文中首次运用“成矿性系数”这一新的参数对丰度模型进行修正,并采用修正后的丰度模型对LSS铀成矿带铀资源量做了较准确的估算。
Due to the lack of quantitative analogy of the metallogenic geological environment in the control area and the prediction area, the abundance model method is more error-prone for evaluating mineral resources and often does not conform to the actual situation. In this paper, the new model of “metallogenic coefficient” is used for the first time to modify the abundance model, and a more accurate estimation of the uranium resources of the LSS uranium metallogenic belt is made using the modified abundance model.
