Feldspar and Nepheline Syenite

Imported nepheline syenite was the major alternative material for feldspar. Feldspar can be replaced in some of its end uses by clays, electric furnace slag, feldspar-silica mixtures, pyrophyllite, spodumene, or talc.

Pseudoleucite syenite and garnet-nepheline syenite differentiated along separate trends, but the two groups are related to the same parental magma by early fractionation of leucite, the presumed precursor of intergrowths of K-feldspar and nepheline. The Diamond Jo nepheline syenite group defines a different differentiation trend.

USGS Scientific Investigations Report 2017-5118: …

Feldspars are minerals that have limited solid solution among three end members: potassium feldspar (K feldspar), sodium (Na) feldspar, and calcium (Ca) feldspar. Potassium feldspar has an ideal chemical formula of KAlSi 3 O 8, with limited Na substitution for K. Potassium feldspar is a common mineral in alkalic and felsic igneous rocks, such as syenite, granite and rhyolite.

Cambrian nepheline syenite complex at Jabal Sawda, …

The only nepheline syenite complex presently known in the Arabian Shield is at Jabal Sawda, about 30 km S of Haql in the extreme NW of Saudi Arabia. It is a post-tectonic, composite intrusion with a crudely concentric structure. A core of leuco-nepheline syenite, a partial ring of mela-nepheline syenite, and an almost complete outer ring of alkali-feldspar syenite are the …

The purpose of this work is a theoretical consideration of equilibrium conditions in the system nepheline-alkali feldspar-plagioclase-alkali chloride aqueous solution based on the thermodynamic treatment of experimental data (Orville, 1963; Iiyama et al., 1963; Debron et al., 1961) for particular systems. The excess thermodynamic functions (ZE, SE, HE, VE) of solid …
