Mineralization at the McBean Brook Zn-Pb-Ag prospect (central New Brunswick) occurs in fault-brecciated Ordovician metasedimentary rocks and Mesozoic diabase dyke rocks. The dyke is interpreted to form part of the early Jurassic Caraquet dyke because it is on strike with the Caraquet dyke, has the same NE-SW orientation, and is similar in mineralogy (containing large plagioclase phenocrysts and olivine) and chemistry (e.g., TiO2 and Ga concentrations and Zr/Y ratios). Thus the mineralization at McBean Brook, consisting of carbonate, quartz, pyrite, pyrrhotite, sphalerite, galena, and chalcopyrite, is probably early Jurassic or younger. Available data indicate chemical similarity with Ordovician massive sulphide deposits near Bathurst, New B...
