Trachyite is the extrusive equivalent of syenite.

The general name is intrusive igneous rock. The specific name depends on the composition. The most well known example is granite, but other common types include diorite, syenite, and gabbro.
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.
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
No, sodalite is a metamorphic mineral, not a rock. It is a blue mineral commonly found in igneous rocks like syenite or nepheline syenite.
Syenites are generally formed in areas where the Earth's crust is the thickest. To produce syenite, you must melt a granitic or igneous rock so that only a portion of the rock has melted. Silica melt is produced when the melting is done slowly and at a very low temperature. This forms syenite.

Trachyite is the extrusive equivalent of syenite.
Usually Granite but also Larvikite, Syenite, Monzonite, Diorite and occasionally Gabbro.

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.
Conglomerate, Sandstone, Shale, Coal Seams, Limestone and Gypsum rock are Sedimentary rocks, while Granodiorite, Granite, Syenite, Diorite, Gabbro, Peridotite and Dunite are Igneous rocks.
The general name is intrusive igneous rock. The specific name depends on the composition. The most well known example is granite, but other common types include diorite, syenite, and gabbro.
Syenite and granite are both types of igneous rocks, but they have key differences in their composition and geological characteristics. Syenite is primarily made up of feldspar and little to no quartz, while granite contains both feldspar and quartz. Syenite is typically found in intrusions deep within the Earth's crust, while granite is more commonly found near the Earth's surface. Additionally, syenite tends to have a finer grain size compared to granite.
