Feldspars that grow in slow to very slow cooling systems, at low temperatures, separate into two phases: these are “low” feldspars, of albite + microcline compositions and have ordered structures. The unmixed feldspars result in perthite (albite in orthoclase), or more rarely, antiperthite (orthoclase in albite). http://www.minsocam.org/MSA/AmMin/TOC/Articles_Free/1999/Meneghinello_p1144-1151_99.pdf the new school new york acceptance rate

"WebIn the case of NaAlSi 3 O 8 ( albite), the order-disorder relationships appear similar to those of KAlSi 3 O 8, but CaAl 2 Si 2 O 8 ( anorthite) is more highly ordered. In intermediate members of the series, the order-disorder relationships are functions of the variable Si/Al ratio and are coupled to the distribution of Na + and Ca 2+ as well. " - Albite disordered
