Why Does Limestone Make Nonfoliated Marble

Limestone is an essential mineral commodity of national importance.

Why does limestone make nonfoliated marble.

Limestone has long fascinated earth scientists because of its rich fossil. Limestone has two origins. 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. Marble is formed from limestone when the limestone is affected by heat and high pressure during a process known as metamorphism.

Products made with limestone. Nonfoliated does not have distinct layers or bands. Metamorphic rocks that do not show foliation are called nonfoliated rocks. Travertine tufa caliche chalk sparite and micrite are all varieties of limestone.

Limestone is a sedimentary so it cannot be foliated or non foliated. Marble is a non foliated metamorphic rock. 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. Is marble foliated metamorphic rock or non foliated metamorphic rock.

The limestone undergoes metamorhism to slate then phyllite and schist. One common nonfoliated meta morphic rock is marble which develops from limestone. Both limestone and marble are types of rock made of calcium carbonate residues. Some of the many products made using limestone are shown in this photograph.

And 2 mechanical transport and deposition of preexisting limestones forming clastic deposits. Breakfast cereal paint calcium supplement pills a marble tabletop antacid tablets high quality paper white roofing granules and portland cement. During metamorphism the calcite limestone recrystallizes forming the interlocking calcite crystals that make up the marble. All are foliated metamorphic rocks and the foliation is easily seen in the orientation of the mica.

But the limestone layer consisting just of calcite has undergone the same temperatures and pressures but remains unfoliated. 1 biogenic precipitation from seawater the primary agents being lime secreting organisms and foraminifera.
