The history of Phillip Island begins under the sea over 500 million years ago, with spectacular outcrops of Cambrian greenstones at Kitty Miller Bay, Devonian granite at Cape Woolamai and columnar basalt at The Colonnades. Put your geologist hat on and visit Pyramid Rock not just for the iconic landscape, but to investigate how the island potentially formed - small granite islands in a shallow ocean covered by extensive flows of basaltic lava? | https://weekendgeology.com/2018/09/01/phillip-island/ | #phillipisland #basalt #capewoolamai #cambrian #greenstones #westernport #geology #geosite

Fossils found by volunteers on the shore platforms surrounding The Great Otway National Park tell us dinosaurs were wondering around Victoria in the ice-cold Early Cretaceous. | https://weekendgeology.com/2016/07/11/dinosaurs-in-the-otways/ | #theotways #cretaceous #dinosaurs #fossils #museum #fossildig

Studley Park - just outside the Melbourne CBD - is the perfect place to learn some of the basic concepts of structural geology! Layers of interbedded sandstones and mudstones deposited on the sea floor during the Silurian (~400 Ma) have been tightly folded during major deformation events. You can also see how the landscape has been shaped by the differential erosion along the contact of Cenozoic basalts (Merri Creek) and rigid sandstone (cliff). | https://weekendgeology.com/2017/02/06/studley-park/ | #melbourne #studleypark #geology #folds #faults #silurian #turbidites #basalt

Eagle Rock (20m stack) and Table Rock near Aireys Inlet, VIC, are weathered outcrops of Oligocene (23Ma+) sub-aerial basalt flows, including pyroclastics and pillow basalt structures, overlain by shallow water limestones with numerous invertebrate fossils (oysters, sea urchins, gastropods and foraminifera). | https://weekendgeology.com/2015/05/30/eagle-rock-aireys-inlet/ | #vicroria #geology #basalt #aireysinlet #eaglerock #pyroclastics #oligocene #weekendgeology

Bendigo, a regional town in Victoria, was once a bustling gold rush settlement littered with poppet-heads, mullock heaps and the deafening soundtrack of stamping batteries. Bendigo is situated within a large Phanerozoic Orogenic Gold Provence, with the largest concentration of deep shafts in the world taking advantage of high grade reefs of quartz-hosted visible gold. Bendigo geology in a nutshell is: sandstones and shales (turbidites) folded into north-south trending chevron folds with steep west-dipping faults.

I probably wouldn’t advise casually visiting the Western Arthurs in South West Tassie on a quiet weekend. The remote range is accessed via a punishing 5-10 day Treck, with unpredictable weather and precarious descents. However, the spectacular sights speak for themselves. The track traverses highly deformed and weathered Pre-Cambrian Quartzites and Schists speckled with dark glacier-carved valleys and lakes | photos: Taron Naoroji | #tasmaniangeology #folds #quartzites #glaciallakes #peaks #treck #rain #hail #hiking #wavyrocks #westernarthurrange #southwestnationalpark

Have fun being a geologist for the weekend but please don’t take home cool rocks as a momento. If everyone did that, there’d be nothing to look at! Please take home photos instead.
