Sedimentary exhalative deposits

Copper ore from the sedimentary exhalative deposit at Rammelsberg, Germany

Banded massive sulfide (silver-lead-zinc ore) from the Sullivan Mine, BC. Note the apparent soft-sediment deformation. Sullivan mineralization is interpreted to be related to black smoker-type seafloor deposition.

Banded massive sulfide (silver-lead-zinc ore) from the Sullivan Deposit, Aldridge Formation, Mesoproterozoic, 1470 Ma; Sullivan Mine, BC

Sedimentary exhalative deposits (SedEx deposits) are ore deposits which are interpreted to have been formed by release of ore-bearing hydrothermal fluids into a water reservoir (usually the ocean), resulting in the precipitation of stratiform ore.

SedEx deposits are the most important source of lead, zinc and barite, a major contributor of silver, copper, gold, bismuth and tungsten.
