Abstract

IN this communication the direct electron-optical resolution of anti-phase domain patterns in a plagioclase feldspar is recorded. (The specimen, from Frederiksvärn, Norway, was kindly provided by Dr. P. H. Ribbe. A partial chemical analysis, made by J. H. Scoon, yielded KAlSi3O8, 3.4 per cent; NaAlSi3O8, 45.2 per cent; CaAl2Si2O8, 51.8 per cent by weight.)
