Abstract: Abstract: The information about discrete and qualitative mineral occurrences is digitalized by supplementing the information of mineral (mineralization） occurrences and using the method of meshing of the values and data of the sizes of mineral occurrences. The definition of the mineralization coefficient is proposed and its geological implication is explained, and the method of delineating mineralization anomaly areas by using mineralization coefficient isolines for mineral resource prognosis is introduced. Take Heilongjiang for instance, the authors have delineated the gold mineralization anomaly areas and selected optimum ore prospects. In comparison with traditional methods, this method is objective and simple. It can be applicable to mineral resource prognosis at medium and small scales and assessments of mineral resource potential.
