This workshop will present an overview of sediment-hosted Zn-Pb-Ag ores from syngenetic and diagenetic environments to high temperature carbonate replacement with a strong emphasis on exploration.

This workshop will present an overview of sediment-hosted Zn-Pb-Ag ores from syngenetic and diagenetic environments to high temperature carbonate replacement with a strong emphasis on exploration. The workshop will focus on clastic-dominated (SEDEX), Mississippi Valleytype, sandstone-hosted, salt diapir environments and high temperature polymetallic vein and carbonate replacement deposits. The course will review the origin of the ore fluids, metal solubility, transport and precipitation mechanisms, igneous associations, and alteration. Presentations on the geologic and tectonic controls on their distribution in the Earth’s crust through time will provide insight into where and how sediment-hosted Zn-Pb-Ag deposits form and the implications for exploration. Classic sedimenthosted Zn-Pb-Ag deposits will be described and samples of ores and alteration products from around the world will be available for the participants to examine.
