What is the parent rock of basalt?

Some metamorphic rocks form due to contact metamorphism, as a result of heat from a nearby intrusion of magma.

What is the parent rock of granite?

Metamorphic Rock Classification

Is basalt a parent rock of amphibolite?

Mafic igneous rocks (e.g., basalts and gabbros) and sedimentary dolomite can be the parent rocks of amphibolite.

Is basalt a parent rock of Hornfels?

Common protoliths of hornfels include sedimentary rocks such as shale, siltstone, sandstone, limestone and dolomite; igneous rocks such as basalt, gabbro, rhyolite, granite, andesite and diabase; or, metamorphic rocks such as schist and gneiss.

What metamorphic rock is formed 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 parent rock of quartzite?

The parent rock to quartzite is sandstone. Quartzite forms from the recrystallization of quartz grains in the sandstone and often the resulting metamorphic rock will preserve vestiges of the original bedding patterns .

What is limestone parent rock?

Limestone is the parent rock of marble.

Is basalt metamorphic rock?

Intense heat or great pressure transforms basalt into its metamorphic rock equivalents.

What is phyllite parent rock?

phyllite, fine-grained metamorphic rock formed by the reconstitution of fine-grained, parent sedimentary rocks, such as mudstones or shales.

What is the parent rock of peridotite?

Layered peridotites are igneous sediments and form by mechanical accumulation of dense olivine crystals. They form from mantle-derived magmas, such as those of basalt composition.

What is basalt a protolith for?

Basalt is the most common mafic protolith. It can turn into mafic metamorphic rocks such as greenschist and amphibolites with chlorite, actinolite, biotite, hornblende, or plagioclase in them, depending on metamorphic grade. calcareous—Calcareous rocks are calcium-rich rocks.

Which rock is called parent rock?

In the context of metamorphic rocks, the parent rock (or protolith) is the original rock before metamorphism occurred.

What is marble’s parent rock?

Parent Rock. Limestone or Dolostone. Metamorphic Environment. Variable grade regional or contact metamorphism along a convergent plate boundary.

What is the parent rock of anthracite?

bituminous coal

Anthracite Coal – Low grade (if T is too high, the coal turns to graphite), Parent Rock = bituminous coal.

What is Hornfels parent rock?

Parent Rock. Shale or Mudstone. Metamorphic Environment. Contact metamorphism; immediately adjacent to igneous intrusion at shallow depths.

What is the parent rock of shale?

Metamorphic Rocks

What is the parent rock of mica schist?

Mica Schist

What is the parent rock of calcite?

Classification of Non-foliated Metamorphic Rocks

Is basalt a sedimentary rock?

Basalt is not a sedimentary rock. It is actually an igneous rock formed from cooled, melted rocks.

What is the origin of basalt?

Basalts are formed by the rapid cooling of basaltic lava, equivalent to gabbro-norite magma, from interior of the crust and exposed at or very close to the surface of Earth. These basalt flows are quite thick and extensive, in which gas cavities are almost absent.

How is basalt formed in the rock cycle?

Basalt forms when lava reaches the Earth’s surface at a volcano or mid ocean ridge. The lava is between 1100 to 1250° C when it gets to the surface. It cools quickly, within a few days or a couple weeks, forming solid rock. Very thick lava flows may take many years to become completely solid.

Which type of rock is basalt?

extrusive igneous

basalt, extrusive igneous (volcanic) rock that is low in silica content, dark in colour, and comparatively rich in iron and magnesium. Some basalts are quite glassy (tachylytes), and many are very fine-grained and compact.

What is made up of basalt rock?

Basalt is a dark-colored, fine-grained, igneous rock composed mainly of plagioclase and pyroxene minerals. It most commonly forms as an extrusive rock, such as a lava flow, but can also form in small intrusive bodies, such as an igneous dike or a thin sill. It has a composition similar to gabbro.

How are basalt and granite formed?

Basalt and granite are both silicate rocks which contain common minerals such as feldspar and pyroxene. They also are both very common rocks on Earth. Furthermore, they are both igneous, meaning that they form from direct crystallization of molten rock.
