     · Anorthoclase feldspar [(Na,K)(Si 3 Al)O 8] comprised up to 17% and may be the primary mineral from which the illite had formed. There was also approximately 39% quartz and approximately 8% calcite. When the sample was heated to 800°C the sample was relatively unchanged although loss of hygroscopic moisture probably occurred between 50 and 150°C.
