Abstract

Sediment hosted Zn+Pb sulphide deposits are the primary source of global lead and zinc. Their secular distribution is well defined, however the duration of individual mineralisation events is less so. By coupling modern H2S production data from sedimentary/hydrothermal environments and metalliferous fluid flux calculations with data on the size concentration and distribution of the world class Navan Zn-Pb deposit in Ireland, it is postulated that the deposit could have formed within a relatively rapid, integrated timeframe of similar to 26,000 years. Ore fluid influx, driven by convection and seismicity, is assumed to be the most limiting factor. In this study, bacteriogenic sulphide availability is not considered to be a limiting factor.
