    The plagioclase feldspars are a set of minerals that are in a series from a sodium rich end member albite to a potassium rich end member anorthiteOften feldspars are simply referred to as plagioclase and orthoclase a K feldspar because identification to greater precision is difficult with ordinary methodsThese details about different kind of feldspar mineralAlkali feldspar has the formula KAlSi 3 O 8 potassium aluminosilicate The formula actually is a blend ranging from all sodium albite to all potassium microcline but albite is also one endpoint in the plagioclase series so we classify it there
