Is Marble an igneous sedimentary or metamorphic rock?

Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. It is composed primarily of the mineral calcite (CaCO3) and usually contains other minerals, such as clay minerals, micas, quartz, pyrite, iron oxides, and graphite.
A.

Is marble metamorphic igneous or sedimentary?

Marble is another example of a metamorphic rock. It is formed from limestone. Metamorphic rocks sometimes contain fossils if they were formed from a sedimentary rock, but the fossils are usually squashed out of shape. Metamorphic rocks can be formed from any other type of rock - sedimentary or igneous.
B.

Is Clay sedimentary igneous or metamorphic?

Clay is a very fine-grained sedimentary rock. It is soft and crumbly when dry, and sticky when wet. Buried clay gradually turns to claystone and shale. Sandstone is a medium-grained sedimentary rock made from sand grains.
  • What is the difference between sedimentary and igneous rocks?

    Igneous rock , formed by the cooling of magma (molten rock) inside the Earth or on the surface. Sedimentary rocks, formed from the products of weathering by cementation or precipitation on the Earth's surface. Metamorphic rocks, formed by temperature and pressure changes inside the Earth.
  • Is shale sedimentary igneous or metamorphic?

    Shale. Shale is a fine-grained, clastic sedimentary rock composed of mud that is a mix of flakes of clay minerals and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite.
