What metamorphic rock is produced from basalt?
Slate (metamorphic) if put under more pressure could change into a schist. A basalt (igneous) could also become a schist. Limestone (sedimentary) can become marble. Metamorphic rocks record how temperature and pressure affected an area when it was forming.
What is the metamorphic rock formed from limestone?
rock marble
Limestone, a sedimentary rock, will change into the metamorphic rock marble if the right conditions are met. Although metamorphic rocks typically form deep in the planet’s crust, they are often exposed on the surface of the Earth.
What is the parent rock of basalt?
| Foliated Metamorphic Rocks | ||
|---|---|---|
| Crystal Size | Mineralogy | Parent Rock |
| medium to coarse | amphibole, plagioclase, biotite, quartz | basalt |
| medium to coarse | plagioclase, orthoclase, quartz, biotite, amphibole, pyroxene | basalt, granite, shale |
| Nonfoliated Metamorphic Rocks |
What types of rocks are basalt?
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.
What type of metamorphic rock does basalt turn into?
Eclogite (“ECK-lo-jite”) is an extreme metamorphic rock formed by regional metamorphism of basalt under very high pressures and temperatures. This type of metamorphic rock is the name of highest-grade metamorphic facies.
What are the traits of a metamorphic rock?
Characteristics of Metamorphism. In general, a metamorphic rock is coarser and has a higher density and lower porosity than the rock from which it was formed. Under low grade metamorphic conditions, the original rocks may only compact, as in the formation of slate from shale.
What are the names of metamorphic rocks?
There are two basic types of metamorphic rocks: 1) foliated metamorphic rocks such as gneiss, phyllite, schist and slate which have a layered or banded appearance that is produced by exposure to heat and directed pressure; and, 2) non-foliated metamorphic rocks such as marble and quartzite which do not have a layered or banded appearance.
Is metamorphic rock the oldest type of rock?
Characteristics of Metamorphic Rocks. One of the oldest types of rocks on our planet, metamorphic rocks are mainly formed due to changes in the parameters of temperature and pressure, which act on the parent…
