Slate is silt changed under pressure.
Metamorphic rocks are formed when existing rocks are subjected to high heat and pressure, causing them to recrystallize into new forms without melting. This process typically occurs deep within the Earth's crust or mantle.
To form metamorphic rock from magma, first magma must intrude into existing rock layers. The heat and pressure generated by the magma will cause the surrounding rocks to recrystallize and change mineral composition, transforming into metamorphic rock. This process occurs deep within the Earth's crust and can take millions of years.
Any type of rock, such as sandstone, shale, limestone, or granite, can be heated and squeezed under high pressure to transform into a metamorphic rock. The intensity of heat and pressure will determine the specific type of metamorphic rock that forms.
Anthracite is a metamorphic rock. Anthracite is formed when an organic sedimentary rock - coal - is compressed and heated in the ground.
Metamorphic rocks can be formed from any pre-existing rock type (igneous, sedimentary, or other metamorphic rocks) that undergoes intense heat, pressure, or chemical changes without melting. This process causes the minerals in the rock to recrystallize and reorganize, resulting in a new metamorphic rock with different properties.
A metamorphic rock formed where rocks have been heated but not deformed is called a contact metamorphic rock. This type of rock forms when existing rocks are altered by the heat from nearby magma without experiencing significant pressure or deformation. Examples include hornfels and marble.
anthracite coal is the metamorphic form of bituminous coal which is the sedimentary form. in other words it has been heated under pressure.
Rocks formed from high temperature and pressure include metamorphic rocks such as marble, schist, and gneiss. These rocks are created deep within the Earth's crust through the transformation of existing rock types under intense heat and pressure conditions.
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.

If it is squeezed and heated sufficiently to realign the minerals or form new minerals, it is called a metamorphic rock. If it is squeezed and heated enough to melt, then solidify, it would be called an igneous rock.
Marble is formed from limestone being buried, heated and subjected to pressure, causing minerals to recrystallise into different atomic structures, forming different minerals to the original limestone. In laymans terms this is the process that occurs to form all metamorphic rocks. The type of metamorphic rock formed is dependant on the chemical and mineral composition of the source rock, and the amount of heat and pressure the source rock is subjected to.
Yes, a metamorphic rocks is an existing rock that has been transformed via heat and pressure.
