gneiss
Shale that is exposed to high temperature and pressure and turned to slate is an example of the metamorphic process.
Slate. Slate is a low grade metamorphic rock derived from shale or mudstone.
mudstone and shale. These can become the metamorphic rock slate if exposed to high pressure and temperature.
High pressure can cause the formation of the metamorphic rock slate from the sedimentary rock shale.
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.
Slate is the metamorphic rock that forms from shale after it is exposed to heat and pressure for a llllloooooonnnnnnnggggg time.
Slate forms from shale under pressure.
Slate is formed out of a sedimentary rock called Shale. It is a foliated metamorphic rock.
Shale that is exposed to high temperature and pressure and turned to slate is an example of the metamorphic process.
Slate is the metamorphic rock, formed from regional (heat and pressure applied) metamorphism on shale.
Slate. Slate is a low grade metamorphic rock derived from shale or mudstone.
Slate
Slate is a metamorphic rock formed from the parent rock shale.
Slate. Slate is a low grade metamorphic rock derived from shale or mudstone.
mudstone and shale. These can become the metamorphic rock slate if exposed to high pressure and temperature.
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.
shale is metamorphic, which means time, pressure and temperature has altered it. Sandstone is sedimentary which means it was formed under water. generally sandstone is younder.
