The Potash-Soda Feldspars
ABSTRACT. Both potash- and soda-feldspar end-members are believed to be trimorphous. The Millard-Michel Levy theory of submicroscopic twinning and the theory of poly- morphism are considered to be independent. The former is not competent to explain the results of thermal analysis or the cusps in the thermal expansion curves.
