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 … WebSuch an evolved fluid could account for the high δ11B and low δ7Li signal reported at ODP Leg 209. The Totalp-Platta-Malenco transect shows prograde alpine metamorphism from prehnite-pumpellyite to epidote-amphibolite facies from north to south.
WebA particular feature of biotite grains from some of the Canadian Appalachian granitic rocks is the presence of lenses of Ca-Al silicates developed along cleavage planes. These from the more to less common are prehnite, pumpellyite and grandite garnet, an intermediate composition between andradite and grossular. Rarely all three minerals can be observed …
WebAlong with the zeolite facies, the prehnite-pumpellyite facies received little attention until about 1950. The first rocks of the facies were described in New Zealand and Celebes. The facies is transitional, bridging the path to the blueschist facies or the greenschist facies. It is particularly well developed in graywacke-type sediments. docuwide 2055 スキャナ ドライバWebSemantic Scholar extracted view of "四面体結合様式, Si2O6 (OH) をもつ鉱物Pumpellyite" by 朗 吉朝 et al.
