The luster of Nepheline syenite is vitreous to dull. It may appear somewhat greasy or waxy in some cases, depending on the specific composition and surface characteristics of the sample.
Extremely iron-rich olivine is rare, but is present in some nepheline syenite. Other minerals common in minor amounts include sodium-rich pyroxene, biotite.
Syenite is primarily used as a dimension stone in construction for countertops, flooring, and decorative purposes. It is also sometimes used in the manufacturing of ceramics and as a source of rare earth elements.
Syenite rock is typically light to medium gray in color. It often contains minerals such as feldspar, hornblende, and quartz, which can give it a speckled or streaked appearance.
Trachyte is an extrusive igneous rock, formed from the rapid cooling of lava on the Earth's surface.
The luster of Nepheline syenite is vitreous to dull. It may appear somewhat greasy or waxy in some cases, depending on the specific composition and surface characteristics of the sample.

An agpaite is any of a variety of peralkaline igneous rocks, particularly nepheline syenite or phonolite.
No, sodalite is a metamorphic mineral, not a rock. It is a blue mineral commonly found in igneous rocks like syenite or nepheline syenite.
Nephrite is a gemstone. It begins with the letter n.
Extremely iron-rich olivine is rare, but is present in some nepheline syenite. Other minerals common in minor amounts include sodium-rich pyroxene, biotite.
Syenite is not granitic. Quartz is one of the main minerals found in granitic rock. Syenite contains little or no quartz, but otherwise has the same general composition as granite.
Syenite is not a common rock, some of the more important occurrences being in new-england, arkansas, montana, new-york(syenite gneiss), switzerland, germany, and norway
Extremely iron-rich olivine is rare, but is present in some nepheline syenite. Other minerals common in minor amounts include sodium-rich pyroxene, biotite, titanite, zircon, iron oxides, apatite, fluorite, melanite garnet, and zircon. Cancrinite occurs in several nepheline-syenites.
Syenite is used as a decorative stone in construction and landscaping due to its attractive appearance and durability. It is also used in the production of ceramics and glass as a fluxing agent. Additionally, syenite can be used as a source of potassium for fertilizer production.
It's found inside the Earth.
