Slate is the metamorphic rock formed from shale.
A pile of mud can turn into shale (a fine-grained sedimentary rock) with relatively low pressure, about 3 mi (5 km) down into the earth. With more pressure and some heat, shale can transform into slate. Metamorphic rock found closer to Earth's surface, or produced by low pressure, characteristically splits or flakes into layers of varying thickness. This is called foliation. Slate is often used as roofing tiles and paving stones.

What is the difference of basalt and shale?
Basalt is a fine-grained, dark-colored volcanic rock that is rich in iron and magnesium minerals, formed from lava flows. Shale is a fine-grained sedimentary rock composed of clay minerals that have been compacted and hardened over time. Basalt is igneous in origin, formed from magma, while shale is sedimentary, formed from the accumulation of clay and silt particles.
What is slate formed by?
Slate is formed from the metamorphism of shale or mudstone. This process involves intense heat and pressure which causes the shale to recrystallize into a fine-grained, foliated rock with excellent cleavage properties.
Is granite gneiss marble limestone shale or basalt an igneous rock?
These are sedimentary rocks. Sandstone is made of compressed grains of rock and sand. Shale is made of compressed bits of mud and clay. Limestone is made of compressed pieces of forms of calcium carbonate.
Is Slate is metamorphic?
yes, slate is metamorphic rock
What are examples of igneous metamorphic and sedimentary rocks?
Igneous: * Obsidian * Granite * Diorite * Gabbro * Pumice * Basalt Metamorphic: * Slate * Phyllite * Gneiss * Mica schist * Marble * Quartzite * Granulite Sedimentary: * Limestone * Sandstone * Shale * Chert * Mudstone * Chalk
Can basalt turn into shale?
No, basalt cannot turn into shale. Basalt is an igneous rock formed from the cooling of lava, while shale is a sedimentary rock formed from the compaction of clay or mud. The processes that form these two types of rocks are different, so basalt cannot directly change into shale.
What is a metamorphic formed from shale?
Slate
How is garnet mica formed?
A Mica Garnet schist is a metamorphic rock formed from a shale or a granitic mother rock when this is squashed and heated at death in the crust.
What is a metamorphic rock formed from a shale?
Slate. Slate is a low grade metamorphic rock derived from shale or mudstone.
Is slate a metamorphic rock which transforms from shale?
Slate is a metamorphic rock formed from the parent rock shale.
What rocks would most likely be found on the ocean floor shale granite basalt or marble?
Basalt would most likely be found on the ocean floor, as it is a common igneous rock formed from the solidification of lava. Shale, granite, and marble are all less likely to be found on the ocean floor, as they are sedimentary and metamorphic rocks that are not typically formed in marine environments.
What is metamorphic rock formed from shale?
Slate. Slate is a low grade metamorphic rock derived from shale or mudstone.
What mineral is formed when shale and basalt are exposed to low-grade metamorphism?
When shale and basalt are subjected to low-grade metamorphism, the mineral formed is typically clay minerals, particularly illite or chlorite. In the case of basalt, the alteration can lead to the formation of minerals like zeolites as well. The metamorphic process involves the recrystallization of existing minerals under heat and pressure, resulting in these secondary minerals.
What kind of rock is formed from the metamorphic of shale?
The first metamorphic rock to form from shale is slate. With further metamorphosis you get phyllite, then schist, then gneiss.
What rock is formed when coal is transformed to metamorphic rock?
shale
What is sedimentary rock formed by deposit of shale?
Slate is the metamorphic rock, formed from regional (heat and pressure applied) metamorphism on shale.
What is the difference of basalt and shale?
Basalt is a fine-grained, dark-colored volcanic rock that is rich in iron and magnesium minerals, formed from lava flows. Shale is a fine-grained sedimentary rock composed of clay minerals that have been compacted and hardened over time. Basalt is igneous in origin, formed from magma, while shale is sedimentary, formed from the accumulation of clay and silt particles.
