Re-Os Evidence Used to Link Regional Mineralization Processes to the Chesapeake Bay Bolig’s Impact in the Northeastern United States

Rhenium-Osmium (Re-Os) isotope measurements of sulfide minerals from 10 occurrences that span a radial distance of over 200 Km serve to geochemically link epithermal mineralization in Pennsylvania to an Eocene event. The most likely geologic event that could have influenced the area during the Eocene is the Chesapeake Bay impact event. The significance of the discovery is twofold: to date no epithermal mineralization has been linked to the Chesapeake Bay impact nor has the process been clearly identified throughout the region. The results effect road construction plans for Pennsylvania, Maryland, and Virginia near the meteor impact site because mineralization could occur in any age strata that lie along fracture traces identified in this contribution.
