WebOccurrence in Wales: pumpellyite is widely developed across Wales occurring as a product of low-grade metamorphic alteration of basic lavas and intrusions, principally of Palaeozoic age. The first description of pumpellyite in the British Isles was made by Nicholls (1957), who reported it from altered basic lavas of Ordovician age at Llanelwedd Quarry, near … Web紙製黒箱50㎜×50㎜×25㎜.母岩約43㎜×40㎜×31㎜. 母岩全体の重量約60g.
