Size of sediment particles determines a rock's classification
Laminated rock is a type of sedimentary rock structure that features laminae. Laminae are representative of periods of sedimentation where thin beds with differing grain size, color or lithology are deposited. They usually appear as a succesive sequence of parallel banding of 10mm or less in a rock sample or facies.
no shale is not magnetic
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.
compacting and cementaing heat and pressure melting
Shale
Silt and clay size sediments form shale.
fine-grained sediment
clay
Shale beaches are formed from the deposition of sediment form nearby shale cliffs which are eroded. The shale can also be deposited at a beach due to longshore drift.
Shale is made from layers of mud and clay pressed together. :)
Compaction
Silt and clay size sediments form shale.
Any kind of rock can be "destroyed" when it comes down to it. If the question is whether sedimentary rock can be changed so that it is no longer the same kind of rock, the answer is - YES.Under sufficient pressure and temperature, most kinds of sedimentary rock transform into a related metamorphic rock.slate pretty much always comes from shale - and can further transform in to phyliteschist starts out as clay or mud which become shale (sedimentary rock) and through multiple transition steps over a long time eventually becomes schistgneiss may be formed from sedimentary rocklimestone (a sedimentary rock) can be transformed in to marblesand can become sandstone (sedimentary rock) and further transform into quartzitesandstone, shale, and limestone can be transformed into hornfels
Slate is a metamorphic rock which originated typically as a shale, or mudstone/claystone, and is usually associated with Regional Metamorphism (intense pressure with heat). This can be due to overburden, continental collision or other large scale compressional geological processes.
Examples would be: limestone, chalj, dolostone, sandstone, conglomerate and some types of shale.
