Orthoclase as a Feldspar Mineral. Orthoclase is a member of the alkali feldspar series. The alkali feldspars include albite (NaAlSi 3 O 8), anorthoclase ((Na,K)AlSi 3 O 8), sanidine ((K,Na)AlSi 3 O 8), orthoclase (KAlSi 3 O 8), and microcline (KAlSi 3 O 8). These feldspar minerals form a solid solution series between NaAlSi 3 O 8 and KAlSi …

Orthoclase - Wikipedia

Typically, the pure potassium endmember of orthoclase forms a solid solution with albite, the sodium endmember (NaAlSi3O8), of plagioclase. While slowly cooling within the earth, sodium-rich albite lamellae form by exsolution, enriching the remaining orthoclase with potassium.
