Mineral deposit models in Bulgaria – basic principles, scope and classification scheme

The necessity of development of mineral deposit models in Bulgaria, their basic principles and classification schemes are presented in the paper. Three types of models (descriptive, genetic, and quantitative) for each main deposit type are being developed by a uniform classification scheme of numerous geological, mineralogical, geochemical, industrial, and environmental characteristics and factors. These models will be used as a basis for metallogenic analysis of the ore productivity on the territory of Bulgaria by geological epochs, geodynamic settings, ore-forming systems and regions.
