Atlas Naturalists presentation
Saturday, 5th October
2pm - 4pm
Tura - Marrang Library, Tura Beach
Soils are fundamental to ecological systems. They influence the vegetation types which in turn determine the insects and animals that live there. And to really understand soils we need to think about rocks and their origins.
Mick Harewood has kindly offered to share what he has learned of the geology in our region. Mick’s knowledge derives from his interest in hydrology, soils, and fluvial geomorphology.
To help with us with our planning, please register for this event (button below).
Everyone is welcome to join us for this event, so feel free to share this information with interested friends.
Some geological sites of interest
Rather than an organised field trip, Mick has suggested that people simply look out for the following features as they travel about our local region. He will be discussing these soils and their formation during his presentation.
Pambula River mouth and Rotary Park = red Merimbula metamorphosed mudstone visible
Yellow Pinch cuttings along Princes Hwy = Devonian or Silurian metamorphic strata
Nethercote = Basalt visible just south of the hall, on the right, and volcanic soils
Roadside cuttings on the road back to Eden from Nethercote = Ordovicien metasediments
To see the granite of the Bega batholithe, one only has to drive around the Bega Valley. The poorer Adamalite granite further south is visible at Allen Brook Road (off the Imlay Road) and further west in Yambulla State Forest.
Rhyolite can be seen (with some difficulty of access) at the Nethercote falls or at the access road to the Navy wharf near Edrom. It is also underlying Bournda Nature Reserve, but with few road cuttings is not easily viewed.
