WebThere is little solid solution between alkali feldspars (contain potassium (K) +/- sodium (Na)) and anorthite ( contains Na and or Ca). Although there is extensive mixing of Na and K or Na and Ca in feldspars when they are formed, as the minerals cool they would rather contain only K or Na or Ca (this is a simplification). WebPlagioclase is series of framework silicate minerals in feldspar group. Plagioclase is a continuous series of solid solutions known as the plagioclase feldspar series, rather than a specific mineral with a particular chemical composition. The series ranges from albite to anorthite endmembers (with respective compositions NaAlSi3O8 to CaAl2Si2O8), where …
