Deakin Volcanics green grey and purple
rhyodacite mostly covers Weston. The Deakin Volcanics green grey, purple and cream
rhyolite can be seen between Parkinson St and Namatjira Drive and forms a large outcrop in the park to the east of Cooleman Court. A band of pink and green rhyolitic instrusive
porphyry runs across Weston from west to east. It is fault uplifted on the southern side. Deakin Volcanics red-purple and green-grey rhyodacite with spherulitic texture is along Hindmarsh Drive on the southern border of the suburb. ==References==
