Classification of lead-zinc and polymetallic massive sulfide deposits based on their formational type

Based on analyzing the literature data and studying the patterns of localization of polymetallic deposits in the Russian Federation, the authors developed a classification of formational types of lead-zinc and polymetallic massive sulfide deposits. The article distinguish several key groups (SEDEX, MVT, VMS, and skarn types), as well as their transitional forms. Reference models for the ore deposits are provided. The geological features, mineral composition, and industrial significance of the deposits are described. Particular attention is paid to controversial issues of the classification, including mixed types and criteria for their identification. The results of the investigation allow us to optimize the forecasting, exploration, and development of ore deposits, taking into account their genetic diversity and geodynamic formation conditions.
