Which minerals can be found in all samples of rhyolite and andesite?
Both rhyolite and andesite typically contain the minerals quartz, feldspar (particularly plagioclase and alkali feldspar), and biotite. They may also contain other minerals such as hornblende or pyroxene, though these are more variable. The presence of these minerals contributes to their characteristic compositions and textures. Rhyolite is generally more silica-rich than andesite, resulting in differences in mineral proportions.
Which mineral can be found in all samples of rhyolite and andesiteh igneous rock is dark colored cooled rapidly on Earth's surface and is composed mainly of plagioclase feldspar olivine and pyroxene?
The mineral that can be found in all samples of rhyolite and andesite is typically plagioclase feldspar, which is often present in varying compositions. Rhyolite and andesite are both volcanic rocks that cool relatively quickly on the Earth's surface, leading to their fine-grained textures. While olivine and pyroxene can also be present in these rocks, plagioclase feldspar is the primary mineral characteristic of both rhyolite and andesite.

How is andesite different from rhyolite and basalt?
There are rocks that are extrusive (formed quickly on the surface of the earth) or intrusive (formed within the earth under slow cooling). Both types of extrusive or intrusive rocks can vary in composition from mafic (high iron and magnesium content) to silicic (less heavy ions like Fe and Mg, but with more of the lighter elements like Ca, Na, K, etc.). Extrusive rocks range from most mafic to less mafic as such: Basalt, Andesite, Rhyolite (and are all fine-grained b/c they cooled quickly). Intrusive rocks that cool more slowly and have larger crystals range from most mafic to less mafic as such: Gabbro, Diorite, Granite. Basalt and gabbro have a similar composition, just the crystal size differs from different cooling rates (same for rhyolite and granite).
What type of lava do strato volcanoes have?
Strato volcanoes typically have viscous lava with high silica content, known as andesitic or dacitic lava. This type of lava tends to form steep-sided volcanic cones due to its ability to cool and harden quickly, leading to explosive eruptions.

What types of extrusive igneous rocks are formed by Hekla's lava?
Hekla has erupted all of the different compositions of magma. So you can find basalt, andesite, and rhyolite as well as all the intermediate rock types formed from the different lavas erupted by Hekla.
What are all the different types of igneous rocks?
The main types of igneous rocks are basalt, granite, andesite, rhyolite, and obsidian. Basalt is fine-grained and forms from rapidly cooling lava, while granite is coarse-grained and forms from slow cooling magma. Andesite and rhyolite fall in between these two in terms of grain size, with obsidian being a volcanic glass with no crystals.
What type of lava do strato volcanoes have?
Strato volcanoes typically have viscous lava with high silica content, known as andesitic or dacitic lava. This type of lava tends to form steep-sided volcanic cones due to its ability to cool and harden quickly, leading to explosive eruptions.
Which the following is a fine grained light colored extrusive igneous rock?
fine grained extrusive rocks can contain Potassium and Plagioclase Feldspar, Quartz, Biotite, Amphibole, Pyroxene and Olivine. these are all the choices for every igneous rocks
Does rhyolite of oxygen in it?
Yes. All igneous rocks contain oxygen.
Does rhyolite have silicon in it?
Yes, rhyolite contains a significant amount of silicon dioxide (SiO2), which is the main component responsible for its high silica content. Silicon is present in the form of silicon dioxide in rhyolite.
Identify three minerals that are normally found with quartz in samples of andesite rock?
Three minerals commonly found with quartz in andesite rock are feldspar (specifically plagioclase), biotite mica, and amphibole (such as hornblende). These minerals are all typically present in andesite as part of the overall composition of the rock.
What are the names of all the rocks in snowdonia?
Snowdonia is characterized by a diverse range of rock types, primarily including volcanic rocks such as rhyolite and andesite, as well as sedimentary rocks like slate and mudstone. Key formations include the Snowdon Massif, which is predominantly composed of granite and volcanic rocks. Other notable rock types include metamorphic rocks like schist. The region's geological diversity contributes to its stunning landscapes and rich biodiversity.
