Zhao Jing-ma

Abstract

The article has established grade-tonnage model to 72 porphyry copper deposits of the whole country, according to The Mineral Resources Data Base of the Whole Country. The model types include frequency histogram, cumulative frequency distributing graph and theoretical model with double logarithmic coordinates. Sum up the typical mathematical characteristics separately to grade-tonnage distribution of porphyry copper deposits.
