This was once a huge shield volcano — at least 45 km across, rising more than 800 m above the surrounding country, formed around 19 million years ago as the Australian plate drifted north over a volcanic hotspot. Erosion has since stripped away roughly 90% of it, leaving thick sheets of hard basalt across the plateau. The road that climbs from the coast up to Armidale — Waterfall Way — is named for the rivers that pour over the edges of those old lava flows, and at Ebor Falls the water drops over dramatic columns of basalt. That's the rock this product is made from.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eBecause it came from that setting, the stone is a hard, dense, olivine-bearing tholeiitic basalt that carries one of the highest paramagnetic readings of any basalt available in Australia. Paramagnetism is a measurable physical property of the rock (expressed in CGS units), and iron-rich basalt sits at the top of the scale. Unlike a fertiliser, basalt dust is a slow-acting remineraliser: it feeds soil biology and gradually releases a broad spectrum of minerals as it weathers, rather than delivering a quick nutrient hit. Because it breaks down slowly, a single application keeps working in the soil for a long time.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eCompared to palagonite, Waterfall Way Basalt is harder and less oxidised, and it carries more reactive calcium — much of it held in calcium-rich plagioclase feldspar — which is what makes the two work so well together. Palagonite is itself a form of basalt, but its different mineral structure gives it a different release pattern, so pairing the two broadens both the range of minerals on offer and the timeframe over which they're released. The extra reactive calcium makes this basalt particularly useful in peat-based mixes and acidic soils, where a source of slow, gentle calcium helps buffer the profile without the fast pH swing of lime.
