Photo 3. Typical section tens of metres across of hydrothermal breccia with a variable dark red hue to the groundmass, and fragments of pale grey sovite dykes and green, altered phonolite dykes, all cut by fluorite-carbonate veins, and all overprinted by potassic alteration assemblages including magnetite, biotite, iron-rich chlorite, carbonate and fluorite. Note digestion of pale grey sovite dyke fragments, and the fluorite-carbonate veinlets cutting both the sovite fragments and the red-hued groundmass of the poly-lithic breccia.
