The upper Devonian Boyd Volcanic complex, Eden, New South Wales

摘要: Abstract Intrusive and extrusive silicic rocks intertongue with mafic volcanics sediments in the southern part of Eden‐Comerong‐Yalwal Rift Zone. Late Devonian fish occur sediments. The present stratigraphic scheme ‘Eden Rhyolite’ ‘Lochiel Formation’ separated by an unconformity or disconformity is rejected. In its place, we rename assemblage Boyd Volcanic Complex, formed a terrestrial zone extension. recognition that alkaline Gabo Island Granite intrudes both are overlain Upper Merrimbula Group, provides tight bracket on potential point radiometric time scale.
