Is trachyte intrusive or extrusive?
Trachyte is an extrusive igneous rock, formed from the rapid cooling of lava on the Earth's surface.
What is the luster of Nepheline syenite?
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.
What is the name of the rock that is formed from molten rock that cools deep within the earth?
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.
What is syenite used for?
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.
What is olivine syenite?
Extremely iron-rich olivine is rare, but is present in some nepheline syenite. Other minerals common in minor amounts include sodium-rich pyroxene, biotite.
Is syenite granitic?
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.
Where can syenite be found?
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
Is sodalite metamorphic rock?
No, sodalite is a metamorphic mineral, not a rock. It is a blue mineral commonly found in igneous rocks like syenite or nepheline syenite.
How does synite occur?
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.
What has the author Charles Jacob Koenig written?
Charles Jacob Koenig has written: 'Literature abstracts of ceramic applications of nepheline syenite' -- subject(s): Bibliography, Nepheline syenite, Syenite, Ceramics
What is a coarse-grain intrusive rock often used for buildings and monumentals?
Usually Granite but also Larvikite, Syenite, Monzonite, Diorite and occasionally Gabbro.
Is trachyte intrusive or extrusive?

What are some uses of syenite?
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.
What type of rock is created from sedimentary or igneous?
Conglomerate, Sandstone, Shale, Coal Seams, Limestone and Gypsum rock are Sedimentary rocks, while Granodiorite, Granite, Syenite, Diorite, Gabbro, Peridotite and Dunite are Igneous rocks.
What is the name of the rock that is formed from molten rock that cools deep within the earth?
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.
How is syenite formed?
It's found inside the Earth.
