Which is an igenous rock limestone rhyolite slate or shale?
Rhyolite is an igneous rock. Limestone, slate, and shale are sedimentary rocks.
What has a more felsic composition rhyolite or basalt?
Rhyolite has a more felsic composition than basalt.
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.
The volcanic equivalent of granite is?
The volcanic equivalent of granite is rhyolite. Both granite and rhyolite are composed mainly of light-colored minerals such as quartz and feldspar, but rhyolite forms from volcanic magma that cools quickly at the Earth's surface, resulting in a fine-grained texture.
Does rhyolite have a more mafic composition than basalt?
Rhyolite is not a mafic rock, but a felsic rock, high in silicates, and similar to granite in composition.
What is the rock hardness of obsidean?
Although technically it's not a mineral (but rather a glassy form of rhyolite containing predominantly orthoclase, quartz, and mica), obsidian would fall into the 5 - 5.5 range on the Mohs scale of hardness.
Is rhyolite a compound?
No. Rhyolite is a mixture.
Is rhyolite igneous?
yes, rhyolite is igneous
Does rhyolite or basalt have more silica in it?
rhyolite
Is rhyolite monomineralic or polymineralic?
polymineralic igneous rock!
How old is rhyolite rock?
Rhyolite can be any age.
Are granite and rhyolite similar in a way?
Yes. Rhyolite and granite have the same composition. Rhyolite is the volcanic equivalent of granite.
What is the intrusive counterpart of rhyolite?
The intrusive counterpart of rhyolite is granite.
Is rhyolite a metamorphic rock?
No. Rhyolite is an extrusive igneous rock.
Is rhyolite's texture a aphanitic?
Rhyolite may be aphanitic or porphyritic.
How is rhyolite categorized?
Rhyolite is a felsic extrusive igneous rock.
What is the hardness of a volcanic rock?
Volcanic rocks can vary in hardness depending on their mineral composition. On the Mohs scale of mineral hardness, most volcanic rocks fall between 5 to 7, with basalt being around 6 and rhyolite around 7.
