Why Does Limestone Make Nonfoliated Marble

All are foliated metamorphic rocks and the foliation is easily seen in the orientation of the mica.

Why does limestone make nonfoliated marble.

Products made with limestone. Even though their chemical nature is almost similar to each other there are many differences between limestone and marble in the way they originate and the physical characteristics they possess. Travertine tufa caliche chalk sparite and micrite are all varieties of limestone. During metamorphism the calcite limestone recrystallizes forming the interlocking calcite crystals that make up the marble.

Limestone is a sedimentary so it cannot be foliated or non foliated. Marble is formed from limestone when the limestone is affected by heat and high pressure during a process known as metamorphism. Nonfoliated does not have distinct layers or bands. Both limestone and marble are types of rock made of calcium carbonate residues.

But the limestone layer consisting just of calcite has undergone the same temperatures and pressures but remains unfoliated. Marble is a non foliated metamorphic rock. Limestone vs marble. Is marble foliated metamorphic rock or non foliated metamorphic rock.

Metamorphic rocks that do not show foliation are called nonfoliated rocks. The limestone undergoes metamorhism to slate then phyllite and schist. One reason a metamorphic rock may not display foliation is that it is made up mainly of one type of mineral so that different minerals cannot separate and line up in layers. And 2 mechanical transport and deposition of preexisting limestones forming clastic deposits.

One common nonfoliated meta morphic rock is marble which develops from limestone. 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. Breakfast cereal paint calcium supplement pills a marble tabletop antacid tablets high quality paper white roofing granules and portland cement. 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 has two origins. Limestone is an essential mineral commodity of national importance.
