Product description:Download The downloadable version of this report is supplied in PDF format (18.2MB). Abstract This report describes the geology of the area covered by the Bendigo and part of Mitiamo 1:100 000 mapsheet. It provides descriptions of Palaeozoic to Recent rock units, landforms and physiography, the structural and economic geology, geological history and previous work. The Lower Ordovician marine turbidite, mudstone and shale sequence is the dominant rock unit. It contains one of the most diverse graptolite faunas in the world, and is host to one of the richest goldfields in Australia. The Tabberabberan Deformation during the Middle Devonian is the only major deformation recognised, however, there is evidence of reactivation of some faults in post-Palaeozoic times. Upper Devonian granodiorite, Jurassic dykes and widespread quartz veins intrude the Ordovician sequence. New ideas are presented on post-Palaeozoic rock units recognising a wider time distribution of Tertiary terrestrial and marine sediments. Rock relationships suggest that the White Hills Gravel is at least Early Tertiary, and could be as old as Late Cretaceous. The Bagshot Formation (marine sands) is recognised as overlying the Calivil Formation (deep leads). Bibliographic reference Cherry, D.P. & Wilkinson, H.E.,1994.
