AbstractThe Carboniferous strata of the Tatamagouche Syncline area can be divided into nine lithostratigraphic units: 1) Windsor Group 2) Millsville Formation 3) Boss Point Formation 4) Cumberland Coarse Facies 5) Cumberland Fine Facies 6) Pictou Grey Beds 7) Pictou Lower Red Beds 8) Pictou Middle Red Beds 9) Pictou Upper Red Beds. With the exception of the shallow marine rocks which characterize the Mississippian Windsor Group, the rest of the Carboniferous strata are predominantely fluvial continental in origin. The continental lithofacies range from boulder conglomerates deposited in the proximal alluvial fan environment to sandstones and mudstones deposited in low sinuosity streams. Paleocurrent directions indicate a flow to the north-northwest within the study area. Some variation of this flow may result from evaporite diapirism in anticlinal areas to the north of the study area. Copper, silver, lead, zinc and uranium occurrences are numerous within the study area. The mineralization is closely linked to the presence of coalified plant material within the channel lag sandstones and conglomerates. Exploration models must therefore incorporate paleocurrent studies to correctly predict potential mineralization trends.
