Webplagioclase series Isomorphous series of feldspars ranging in composition between albite (NaAlSi 3 O 8) and anorthite (CaAl 2 Si 2 O 8).Between the two end-members there is a continuous solid solution series: albite, oligoclase, andesine, labradorite, bytownite, anorthite. Usually, the higher the temperature of formation the more likely the feldspar is … WebAug 28, 2024 · Albite is an end member of both the plagioclase and the alkali feldspar series. As with K-feldspar, ordering of AlO 4 and SiO 4 tetrahedra decreases with increasing temperature, leading to minor changes in structure. Low albite’s structure is similar to that of low microcline; high albite’s structure is more disordered. fashmob instagramPlagioclase is a series of tectosilicate (framework silicate) minerals within the feldspar group.
