Developments in mineral deposit modeling / Развитие моделирования месторождений полезных ископаемых

Activities in mineral deposit modeling have continued to develop on several fronts since the publication of “Mineral Deposit Models,” edited by Cox and Singer (1986). That bulletin is a collection of 87 descriptive deposit models and 60 grade and tonnage models prepared by many authors both from within and outside of the U.S. Geological Survey. The present bulletin continues that effort with the addition of new or revised models. Before these models are introduced, a review of modeling as used here is provided as well as an overview of mineral deposit modeling since the publication of Cox and Singer (1986).
