Why does limestone make nonfoliated marble.

Is marble foliated metamorphic rock or non foliated metamorphic rock. The limestone undergoes metamorhism to slate then phyllite and schist. Limestone is an essential mineral commodity of national importance. One common nonfoliated meta morphic rock is marble which develops from limestone.

Travertine tufa caliche chalk sparite and micrite are all varieties of limestone. Breakfast cereal paint calcium supplement pills a marble tabletop antacid tablets high quality paper white roofing granules and portland cement. The pressure applied to the reforming rock causes the differences in the way the rock looks once recrystallized and determines whether it will be foliated or nonfoliated. 1 biogenic precipitation from seawater the primary agents being lime secreting organisms and foraminifera.

Both limestone and marble are types of rock made of calcium carbonate residues. Limestone vs marble. Metamorphic rocks that do not show foliation are called nonfoliated rocks. Nonfoliated does not have distinct layers or bands.

The major differences between foliated and nonfoliated metamorphic rocks are in the areas of texture appearance and the type of pressure applied during recrystallization. Limestone is a sedimentary so it cannot be foliated or non foliated. Limestone has two origins. And 2 mechanical transport and deposition of preexisting limestones forming clastic deposits.

All are foliated metamorphic rocks and the foliation is easily seen in the orientation of the mica. Marble is formed from limestone when the limestone is affected by heat and high pressure during a process known as metamorphism. During metamorphism the calcite limestone recrystallizes forming the interlocking calcite crystals that make up the marble. Some of the many products made using limestone are shown in this photograph.

Marble is a non foliated metamorphic rock. Limestone has long fascinated earth scientists because of its rich fossil.
