Excerpt from Essentials for the Microscopical Determination of Rock-Forming Minerals and Rocks, in Thin Sections
The separation lines between the various plagioclase feldspars have been changed from those given in the former book to 5, 273, 50, and 95 per cent anorthite. Albite and anorthite have been limited to a variation of only 5 per cent since these names are also applied to the pure end members, and compound names such as oligoclase-albite, labradorite-bytownite, etc., have been omitted.
