Background . New viewpoints on the formation of lead and zinc (Pb and Zn) ore deposits in the People’s Democratic Republic of Algeria are presented. Aim . To develop a geological and structural model for the formation of Pb and Zn ore deposits in Algeria within the paleovolcanic structure. Materials and methods . An analysis of the existing materials on the Pb and Zn deposits of the Algerian Republic was conducted. A structural and genetic scheme for the formation of stratiform Pb and Zn deposits in carbonate rocks was proposed using the example of the sulfate-fumarole activity of Mount Erebus volcano. Results . The stratiform ore deposits of Pb and Zn are of the same age (Oligocene), regardless of the age of the host carbonate rocks. Conclusion . The stratiform deposits of Pb and Zn are the products of a volcanic sulfate-fumarole activity of hydrotherms under the cover of carbonate deposits formed on the slopes of a paleovolcanic structure of the Jurassic-Oligocene age.
