The aegirine-augite–nepheline syenite [aegirine foyaite of Bloomfield et al.] generally shows a strong foliation caused by aligned pyroxene, and to lesser extent aligned feldspar and nepheline, prisms. Large microcline perthites are often surrounded and cut by swirling areas of finely granular alkali feldspar which may have been produced by ...

Nov 27, 2019 Pseudoleucite syenite is a magmatic rock, which is rarely found in the foidolite rock group. With respect to the compositions of similar alkali feldspars as sodium potassium aluminosilicates, feldspathoid minerals are normally characterized by silica deficiency. Pseudoleucite syenite formed from alkaline (sodium and potassium)-rich and silica-poor magmas.
