Abstract
The diverse ore mineralogies of more than 100 stratabound sulfide deposits that occur along the length of the Appalachian-Caledonian orogen have been tabulated. The minerals reflect the varying Cu:Zn:Pb ratios that have been used as a means to separate the ore deposits into six distinct types following the IGCP Project 60 guidelines. The ore deposits, each containing at least one million metric tons of ore, are typical of massive sulfide deposits throughout the world and provide a basis for contrasting and comparing this orogen with others. Differing grades of metamorphism have significantly modified the ore-mineral grain sizes and textures, but do not seem to have effectively influenced the number or variety of mineral species present.
