Abstract
IT has long been assumed that the degree of ordering between silicon and aluminium in the tetrahedral sites of feldspars is related to the conditions of formation of the minerals. A direct test of this idea has, up to the present, been hampered by the lack of an easy method of measuring the degree of order in a genetically related suite of feldspars. This communication describes a new method which, while applicable to all alkali feldspars, should be particularly useful for monoclinic potassium feldspars for which there is at present no generally accepted method of determining the degree of aluminium/silicon order short of a full-scale structural analysis.
