葡萄石-绿纤石相（英語：prehnite-pumpellyite facies）是海 … 葡萄石-绿纤石相（英語：prehnite-pumpellyite facies）是海洋地殼在中洋脊擴張中心周圍的變質岩相。它是介於沸石相和綠片岩相之間的過渡變質產物，溫度範圍為 250 至 350 °C，壓力範圍約為 2 至 7 千巴。礦物組合取決於原岩組成。
* 鎂鐵質原岩：礦物組合是綠泥石、葡萄石、鈉長石、绿纤石和綠簾石。
* 超鎂鐵質原岩：礦物組合是蛇紋石、滑石、、透閃石和綠泥石。
* 泥質沉積原岩：礦物組合是石英、伊利石、鈉長石和綠泥石。
* 碳酸鹽沉積物原岩：礦物組合是方解石、白雲石、石英、粘土、滑石和白雲母。泥石。

, De prehniet-pumpellyiet-facies is een meta … De prehniet-pumpellyiet-facies is een metamorfe facies die gekenmerkt wordt door een graad van metamorfose met iets hogere temperaturen en drukken (en diepte) dan de zeoliet-facies. De facies is genoemd naar de twee mineralen prehniet (een calcium-aluminium-fylosilicaat) en pumpellyiet (een sorosilicaat). Zoals bij alle metamorfe facies wordt de prehniet-pumpellyiet-facies vastgesteld aan de hand van bepaalde mineralen die gewoonlijk middels onderzoek naar slijpplaatjes worden gedetermineerd. In metamorfe stollingsgesteenten, grauwackes en pelieten zijn de volgende mineraalsamenstellingen typerend voor de prehniet-pumpellyiet-facies:erend voor de prehniet-pumpellyiet-facies:
, The prehnite-pumpellyite facies is a metam … The prehnite-pumpellyite facies is a metamorphic facies typical of subseafloor alteration of the oceanic crust around mid-ocean ridge spreading centres. It is a metamorphic grade transitional between zeolite facies and greenschist facies representing a temperature range of 250 to 350 °C and a pressure range of approximately two to seven kilobars. The mineral assemblage is dependent on host composition.
* In mafic rocks the assemblage is chlorite, prehnite, albite, pumpellyite and epidote.
* In ultramafic rocks the assemblage is serpentine, talc, forsterite, tremolite and chlorite.
* In argillaceous sedimentary rocks the assemblage is quartz, illite, albite, and stilpnomelane chlorite.
* In carbonate sediments the assemblage is calcite, dolomite, quartz, clays, talc, and muscovite.omite, quartz, clays, talc, and muscovite.
