Which rock is most felsic out of rhyolite andesite and basalt?
Rhyolite is the most felsic rock out of rhyolite, andesite, and basalt. Felsic rocks have a higher silica content and are associated with continental crust. Rhyolite is typically light in color and has a high silica content, making it more felsic compared to andesite and basalt.
What are examples of extrusive rock?
Basalt, Andesite, Rhyolite, Obsidian, Pumice, Tuff, Ash (Lava).
What are types of volcanic rock?
Volcanic rocks are extrusive igneous rocks.
Which igneous rock is an extrusive rock?
Basalt, Rhyolite, Obsidian and Andesite. There's many more but these are the main ones.
What is a common location for Rhyolite rock?
You find rhyolite rock wherever you find andesite volcanoes or extinct andesite volcanoes. Topaz Mountain in western Utah (3 hours west of Provo) is a rhyolite mountain complete with garnet, topaz crystals, beryl, and other gemstones and minerals. If there are no dormant or extinct volcanoes in your area, your chances of finding rhyolite are slim to none.
What is a rock that is unique to volcanoes?
Rocks unique to volcanoes include basalt, andesite, rhyolite, scoria, pumice, and tuff.
What rock types does the Cotopaxi volcano have?
The Cotopaxi volcano in Ecuador is primarily composed of andesite and dacite rock types. Andesite is a volcanic rock with an intermediate composition between basalt and rhyolite, while dacite has a similar composition to andesite but with more silica content.
What is an andesite?
a dark, fine-grained, brown or grayish volcanic rock that is intermediate in composition between rhyolite and basalt.
What is the difference between rhyolite and andesite?
They have different compositions. Most igneous rocks fall into a spectrum ranging from mafic (low silica, dominated by iron, magnesium, and calicum) to felsic (high silica, dominated by sodium and potassium) On this scale rhyolite is felsic while andesite is intermediate. Rhyolite is dominated by the presence of quartz, potassium feldspar, and sodium-rich plagioclase. Rhyolite also tends to contain more volcanic glass. Common colors of rhyolite are light gray, white, and pink. Andesite often contains plagioclase with a fiar balance of sodium and potassium. Plagioclase is also a common dominant mineral. Andesite is darker than rhyolite, ranging from gray to almost black.
Give 10 examples of igneous rock.?
some examples of igneous rocks are granite,basalt,and rhyolite and driolite
The melting point for rhyolite?
The melting point of rhyolite can vary depending on its composition and mineral content, but typically ranges from 700 to 900 degrees Celsius. Rhyolite is a silica-rich volcanic rock that usually melts at higher temperatures compared to basalt or andesite.
What type of extrusive rock would form at a volcano?
Extrusive rock of an igneous origin, formed from the cooling and solidification of lava. Typical examples include basalt, andesite and rhyolite.
