The geology and petrology of the Murrumbidgee bathylith and its relation to the Palaeozoic igneous activity of the Tasman geosyncline

Abstract

The Murrumbidgee bathylith on the Southern Tablelands of New South Wales has intrusive relations to Lower Paleozoic sediments and was probably emplaced in association with the Bowning Orogeny (Late Silurian) which affected large areas of the Tasman Geosyncline. The bathylith is a composite intrusive made up of at least nine distince bodies which range from tonalite to granite, The most common rock type is granodiorite which represents about 85 per cebt of the 550 square miles of exposed bathylith rock.
