Cell parameters and infrared absorption of synthetic high to low albites

Unit cell parameters and infrared absorption data were obtained to provide much needed information for the important alkali feldspar series high albite-low albite, and to substantiate earlier claims of the direct hydrothermal synthesis of ordered albite. The two independent quantitative means of characterization prove that ordered albite has indeed been synthesized, having an estimated 95.3 atomic percent Al in the T₁O site. The data agree well with published data on ordered and disordered albites, but they raise questions concerning lack of agreement with existing data on natural structurally intermediate albites.This paper is taken from a Ph. D. dissertation submitted to the Department of Geology, Stanford University, Stanford, California.
