The phenomenon of antiordering, i.e., preferred Al occupation of the T 2o position of the albite structure, was observed in a two-phase feldspar from Pektusan Volcano, Primorie. This paper reports the results of the computer modeling of this phenomenon. Calculations were carried out in an ionic approximation and confirm that, under ordinary conditions, the most preferable is normal Al ordering in the T 1o position. However, if lattice parameters are fixed at the experimental values obtained for… CONTINUE READING
