Summary:Rosasite, aurichalcite and zincian malachite are reported from calcite-lined vughs at Bute Quarry and also at a depth of 35 m in a borehole at Locks Common, Porthcawl; both localities are in Carboniferous Limestone. At Bute Quarry the primary sulphides are galena, sphalerite and chalcopyrite. Microprobe analyses are reported for rosasite (Sn:Cu 0.46) and three grains of zincian malachite (Zn:Cu 0.11-0.19). The aurichalcite occurs as radiating acicular needles <=2 mm in length, which developed within small cavities between calcite crystals lining the vughs. [R.A.H.]
