摘要
Areal productivity is a quantitative mineral resources evaluation method based on geochemical analysis data. This paper introduces the conception of similarity coefficient to solve the problem. The principle of coefficient calculation is to digitalize the ore-controlling factors then transferred to data model. The model is correlated to a known model area by means of a mathematic algorithm to get the value that shows similarity with the model area. Hence, the results become more reasonable and creditable, and the method worth to use widely in mineral quantitative assessment.
