The Norwood Hydrogeological Landscape (HGL) is characterised by an undulating low hill and rise landscape in the north and partially dissected plains landscapes on terrace surfaces in the south. This HGL extends south from Norwood in southern Launceston toward the rural landscapes in the Relbia east and White Hills north areas. This is an area of moderate rainfall (680 mm). It has preserved regolith and alluvial sediments forming dissected plains and terraces overlying deeply weathered bedded sedimentary rocks and dolerite.
Typical lithologies for this HGL are gravel, sand, silt and clay overlying sedimentary rocks, and in the south west and north east (along the North Esk River), deeply weathered Jurassic dolerite. There are volumetrically small remnants of basaltic lavas preserved on some hill crests in the south. The landscape consists of low hills and rises with moderately to gently inclined slopes (<15°), forming an undulating landscape in the north, and a dissected elevated plains landscape in the south.View Report
