Upper photo: typical section tens of metres across of variable dark red and green hydrothermal breccia, sovite dyke block breccia and green, alteration-mottled phonolite dykes, all cut by fluorite-carbonate veins, and all overprinted by potassic alteration assemblages including magnetite, biotite, iron-rich chlorite, carbonate and fluorite. In lower photo, note digestion of pale sovite dyke fragments, and the fluorite-carbonate veinlets cutting both the light sovite fragments and the red-hued, iron-rich breccia groundmass of the poly-lithic breccia.
