Sedimentary exhalative (SEDEX) ore systems are a primary source for zinc and lead, as well as a significant source of silver, gold, copper, antimony, tin and barite. New SEDEX zinc-lead deposits may be buried far beneath the surface of the Earth. To find the deposits, it is important to understand why certain Canadian sedimentary basins are enriched with zinc and lead, while others are not. Knowing what affects the location, distribution and genesis of SEDEX zinc-lead districts is crucial to lowering the exploration risk inherent in searching for new deposits. The SEDEX project is largely field-oriented and will bring together geology, mineralogy, geochemistry and three-dimensional reconstruction to improve SEDEX zinc-lead exploration models. gccst Geology gccst Scientific research gccst Metals gccst Minerals Canada.
