Abstract:

The Prediction Type of Mineral Resources is a new division method for mineral resources, in the view of metallogenic prognosis and assessment for mineral resources potential. Each prediction type of mineral resources, with mineral deposit type to be its theoretic basement, has a general regularity of typical deposits and is featured by regional geological characteristics. This paper introduces the research history of this new idea of prediction type, and stresses its importance and advantages in assessment work. Based on the case studies of Ashele-type, Dachang-type, Jiama-type and Daye-type, authors discuss the relationship between the metallogeny series and prediction type of mineral resources, implying that the type of mineral deposits can serve as the base of the division of prediction type of mineral resources. In addition, it’s also pointed out that only by strengthening research on ore-forming regularity for each prediction type of mineral resources, it can be applied scientifically to the assessment work of mineral resource potential. Some problems existing in the national use of the concept of prediction type of mineral resource since 2006 are also discussed.

Key words: prediction type of mineral resources, type of mineral deposits, metallogenic prognosis, metallogenic regularity, assessment of mineral resource potential
