GRADE-TONNAGE MODEL OF ORIGINAL GOLD DEPOSITS IN CHINA
Abstract：The grade-tonnage model of deposits belongs to the pre-area ofthe subject, the important part of the system exploration theory. The article establishes a geological model, a grade model, tonnage model and a joint model of grade-tonnage for 680 original gold deposits in China and a tonnage sequence model of quartz-vein gold deposits of the whole country, according to "The Mineral Resources Data Base of the Whole Country in 1997". The model types include frequency histogram, cumulative frequency distributing graph and theoretical model with double logarithmic coordinates. The paper sums up separately the typical mathematical geological characteristics of grade-tonnage distribution of original gold deposits in China and discusses significance and function of the tonnage sequence model in the field of mineral resources evaluation.
