OzGeology is now on Spotify!


We’re proud (and honestly still a bit stunned!) to announce that OzGeology is now available as a podcast on Spotify.

What started as a small YouTube channel exploring Australia's geology, gold discoveries, and natural history has grown into something much bigger — and it’s all thanks to you!

In an incredible moment we never saw coming, OzGeology has:

🏆 Ranked #1 Science Podcast in Australia

🌟 Achieved #8 Overall Top Podcast in Australia — across every category and genre

🎙️ Secured #1 Top Episode in Australia

It’s rare for a science-focused show to break into the top charts dominated by entertainment, news, and lifestyle podcasts — and the fact that a geology podcast has ranked this high shows just how passionate and curious this community really is.

This milestone means so much to us because it proves there’s a real hunger for stories about the ancient landscapes, goldfields, and hidden wonders that shaped Australia. It’s not just about rocks — it’s about history, discovery, and adventure.

If you love learning about the Earth beneath your feet, the secrets locked inside ancient mountains, or the thrill of finding gold, the OzGeology podcast is made for you.

What High Grade Gold Ore Looks Like (Taken From My Hard Rock Mine)

What High Grade Gold Ore Looks Like (Taken From My Hard Rock Mine)

What looks like a plain rock at first glance is actually hiding an incredible secret—pure gold in fine particles, locked within the hard matrix. In this article, I reveal how to identify this type of high-grade ore, explain why it’s so easy to miss, and show the surprising gold recovered from just a small crushed sample.

The Rift That Almost Split New South Wales From Australia

The Rift That Almost Split New South Wales From Australia

Long before the continents settled into their modern forms, eastern Australia nearly tore itself apart. In this video, we unravel the dramatic geologic event that almost saw New South Wales and Queensland break away from the rest of the continent — a failed rift system that shaped the very foundation of eastern Australia. Discover the tectonic forces, basin formation, and ancient crustal stretching that left behind a legacy visible in the landscape today.

The Story of the Centralian Superbasin

The Story of the Centralian Superbasin

The Centralian Superbasin was one of the most dramatic geological features in Australia's ancient past—an enormous inland sea that once covered nearly a quarter of the continent. Formed during the breakup of the supercontinent Rodinia, this vast basin recorded everything from microbial reef-building to global ice ages and mountain-building events. Its legacy lives on in the rocks beneath the Outback, revealing a time when central Australia lay beneath warm, shallow seas teeming with early life.

Australia's Last Stratovolcanoes

Australia's Last Stratovolcanoes

Australia’s serene landscapes hide a violent past marked by towering stratovolcanoes and supercharged eruptions. In this article, we uncover the final days of subduction-driven volcanism on the continent—when the New England Orogen roared with fire, and caldera-forming eruptions reshaped eastern Australia. Discover how these ancient volcanoes formed, why they vanished, and what traces remain today in the rocks beneath our feet.

The Wyalong Deep Lead: A Hidden River of Gold

The Wyalong Deep Lead: A Hidden River of Gold

Beneath a tranquil valley lies a story of ancient erosion and hidden riches. This painting-inspired illustration captures the essence of the Bland Creek palaeovalley — a lost river system once filled with gold-laden gravels, now buried beneath layers of sediment. Titled “The Hidden River of Gold,” the image sets the tone for a journey through deep time, where geology, mystery, and mineral wealth converge beneath the Australian landscape.

Mount Etna's Largest Eruption in Over A Decade

Mount Etna's Largest Eruption in Over A Decade

On June 2, 2025, Mount Etna erupted with a fury not witnessed in over a decade, unleashing a towering ash column and a searing pyroclastic flow that tore down its eastern slopes. This wasn’t just another paroxysm from Europe’s most active volcano—it was a full-scale display of Earth’s raw geologic power. As molten rock and volcanic gases surged skyward, the mountain reminded Sicily and the world why it has been both feared and revered for millennia. But beneath the spectacle lies a story of deep tectonic forces, ancient names, and a volcano that never sleeps.

The Lost Land of the Bassian Plain

The Lost Land of the Bassian Plain

Beneath the waves of Bass Strait lies a lost land once teeming with life — the Bassian Plain. During the last ice age, this vast expanse of grassland, rivers, and forests connected mainland Australia to Tasmania. It was home to megafauna, Aboriginal hunters, and an entire ecosystem now submerged by rising seas. This blog post explores the geology, ecology, and human story of this forgotten world — a true “Atlantis” of the Southern Hemisphere.

Manganiferous Gossans: Formation, Features, and Exploration Significance

Manganiferous Gossans: Formation, Features, and Exploration Significance

Manganiferous gossans are the blackened crusts of weathered ore bodies, where manganese oxides mix with iron rust, precious metals, and base metals. These striking gossans don't just stain the surface—they lock in chemical clues that reveal the hidden mineral systems buried beneath.

How Hydrothermal Breccia-Hosted Gossans Form

How Hydrothermal Breccia-Hosted Gossans Form

Hydrothermal breccia-hosted gossans form when sulphide-rich rocks fracture, weather, and oxidise near the surface, leaving behind colourful, iron-stained zones enriched with secondary minerals. These vibrant crusts are more than just geological curiosities—they’re rich records of past fluid flow, redox changes, and mineral transformation.

Formation and Mineralogy of Carbonate-Hosted Gossans

Formation and Mineralogy of Carbonate-Hosted Gossans

Gossans form when metal-rich sulfide ores near Earth’s surface weather and oxidize, leaving behind vivid caps of iron and secondary minerals. In carbonate rocks, this process produces colorful mixtures of iron oxides, lead and zinc carbonates, and copper stains—offering geologists a surface-level glimpse into the chemistry of buried ore.

Gossans: Rusty Clues to Hidden Ore Beneath the Surface

Gossans: Rusty Clues to Hidden Ore Beneath the Surface

Gossans are the weathered remains of sulfide-rich ore bodies—natural “iron hats” that form when oxygen and water transform underground metal ores into iron-stained, mineral-rich surface rocks. These rusty outcrops not only reveal Earth’s geochemical story but often lead to valuable discoveries hidden just below.

How Cosmic Collisions Create Mineral Deposits

How Cosmic Collisions Create Mineral Deposits

When an asteroid slams into Earth, it does more than create a crater—it reshapes the crust. These cosmic impacts unleash shockwaves, heat, and hydrothermal systems that can concentrate valuable minerals like nickel, copper, platinum, and even diamonds. In craters like Sudbury and Vredefort, ancient destruction has left behind enduring economic treasure.
