Is basalt an igneous or metamorphic rock?
igneous rocks Basalt is a mafic extrusive rock, is the most widespread of all igneous rocks, and comprises more than 90% of all volcanic rocks. Because of its relatively low silica content, basalt lava has a comparatively low viscosity, and forms thin flows that can travel long distances.
Is basalt sedimentary or metamorphic?
Basalt is not a sedimentary rock. It is actually an igneous rock formed from cooled melted rocks.
What type of rocks is basalt?
Basalt is a hard, black volcanic rock. Basalt is the most common rock type in the Earth's crust. Depending on how it is erupted, basalt can be hard and massive (Figure 1) or crumbly and full of bubbles (Figure 2).
What type of metamorphic rock is basalt?
Foliated Metamorphic Rocks | ||
---|---|---|
Crystal Size | Mineralogy | Parent Rock |
fine to medium | green amphibole, green mica, plagioclase | basalt |
medium to coarse | biotite, muscovite, quartz, garnet, plagioclase | shale, basalt |

Is basalt a sedimentary rock?
Basalt is not a sedimentary rock. It is actually an igneous rock formed from cooled, melted rocks.
Is basalt an igneous rock?
Basalts are common aphanitic igneous extrusive rocks composed of minute grains of Plagioclase feldspar (Labradorite), Pyroxene, Olivine, Biotite, Hornblende, and less than 20% Quartz.

What is a common metamorphic rock?
Common metamorphic rocks include phyllite, schist, gneiss, quartzite and marble.
Which is not a metamorphic rock?
The correct answer is Limestone. Limestone is not a Metamorphic rock. Limestone is an example of Sedimentary rocks. Sedimentary Rocks: are formed by the deposition, sedimentation, and lithification of sediments over a long period of time.
What are the examples of metamorphic rock?
Types of metamorphic rocks include gneiss, quartzite, marble, schist, soapstone, and phyllite.
What are metamorphic rocks examples?
Common metamorphic rocks include phyllite, schist, gneiss, quartzite and marble. Foliated Metamorphic Rocks: Some kinds of metamorphic rocks — granite gneiss and biotite schist are two examples — are strongly banded or foliated.
What are the 3 main types of metamorphic rocks?
There are three ways that metamorphic rocks can form. The three types of metamorphism are Contact, Regional, and Dynamic metamorphism. Contact Metamorphism occurs when magma comes in contact with an already existing body of rock.
