  author={Paul H. Ribbe},
The vast array of crystal structure refinements, lattice parameter measurements, optical and spectroscopic data, and electron microscopic observations accumulated on feldspar since W. H. Taylor unravelled the sanidine structure in 1933 has led to detailed understanding of many but by no means all of the diffusive and displacive transformations occurring in both natural and synthetic systems as functions of pressure, temperature, and composition (P,T,X). This paper reviews the basic structural… CONTINUE READING
