AbstractPaleoproterozoic volcanogenic massive sulfide (VMS) deposits, hosted in greenstone districts formed during assembly of Earth¿s first supercontinent 2.1-1.7 Ga, account for a significant component of global VMS tonnage and are an important global exploration target. Amongst these belts, the 1.92-1.80 Ga Trans Hudson Orogen of Canada is the largest and most well-endowed in Laurentia, with over 29 deposits, with 320 MT of Cu-Zn ore. Study of its deposits, districts, and tectonostratigraphic evolution enables greater understanding of the metallogenic processes of the Paleoproterozoic, and VMS deposit formation and preservation at all scales. We briefly overview the Trans-Hudson orogen, its VMS deposits and their exploration history, showing that the tectonostratigraphic and accretionary architecture of the orogen can be predictive in terms of its mineral endowment and that successive phases of pre-and post-accretion volcanism can host major VMS deposits. We present results from a four-year program to investigate the deposits and evolution of the Trans Hudson Orogen, highlighting various approaches at the district and regional-scale to aid deposit discovery in other structurally complex and covered Precambrian terranes,
Summary(Plain Language Summary, not published)
This paper present an overview of a series of eight papers published in the journal Economic Geology as a synthesis of results from the Targeted Geoscience Program-3 Flin Flon project. Results are grouped according to their relevance to targeting for volcanic-hosted massive sulphide deposits which are broad regional- or more district-scale, and will be of relevance to industry and researchers seeking to better understand new approaches to exploration in established mining camps.
