Upper photo: dark, iron-rich hydrothermal breccia at 464m in Hole 2 incorporating disaggregated blocks of sovite and sovite-flourite dykes, and itself cut by fluorite-carbonate veinlets. Lower photo: wholesale replacement of host rock at 73m in Hole 2 by potassic alteration facies of magnetite, biotite, carbonate, fluorite and pyrite, and itself cut by pyrite and fluorite-carbonate veinlets.
