WebMay 19, 2015 · Paleopiezometry estimation indicates that flame perthite formed under the influence of low to moderate differential stress on granitoids. Most of the perthites occurs in these granitoids are compositionally albite to oligoclase in nature. The composition ranges X Ab: 0.98–0.49 for the Malanjkhand and X Ab: 0.96–0.49 for Dongargarh granitoids.
