This excursion was designed with the intent of introducing its participants to the geology, mineralisation and alteration styles present in the Moonta - Wallaroo region, through guided drill core inspection, a trip to the Wheal Hughes open pit mine, and field examination of granites and metasomatic rocks. To give attendees a better understanding of the regional tectonic evolution, the excursion group also visited some outcrops of late Palaeoproterozoic Wallaroo Group sediments, and middle Palaeoproterozoic Donington Granitoid Suite basement and paragneiss. During a two-day field trip highlighting the broad deformational history of the south-eastern margin of the Gawler Craton and its mineral potential, geological features were visited and described that give evidence of: - migmatisation, metamorphism and folding events - deformation of granites and metasediments - Palaeoproterozoic bi-modal magmatism and back-veining structures - flow banding and hyaloclastites in the Wallaroo Group - Mesoproterozoic granite-mafic cumulate intrusions and related alteration; and - fault-controlled mineralisation styles. The excursion itinerary was: Day one: depart 8.00 am from Adelaide . 1.1 Wheal Hughes mine 11.00-12.00 am . 1.2 PIRSA Moonta core library 12.00-1.30 pm (lunch) . 1.3 Point Riley 1.30-2.30 pm . 1.4 North Beach 2.30-3.30 pm . 1.5 Oorlano quarry 3.30-4.00 pm . 1.6 Wallaroo mine ruins 4.00-4.30 pm . 1.7 New Cornwall mine 4.30-5.00 pm (motel, dinner) Day two: start 8.00 am from Patio Motel, Moonta Bay . 2.1 Port Victoria 9.00-11.00 am . 2.2 Corny Point 12.00-2.00 pm (lunch) . 2.3 Berry Bay 2.00-2.30 pm . 2.4 Gleesons Landing 2.30-3.30 pm . 2.5 Royston Head 3.30-4.30 pm . 2.6 Point Yorke 4.30-5.00 pm Return to Adelaide around 7.30 pm.
