Why Does Limestone Make Nonfoliated Marble

Limestone has long fascinated earth scientists because of its rich fossil.

Why does limestone make nonfoliated marble.

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. 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. Marble is a non foliated metamorphic rock.

Limestone vs marble. 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. All are foliated metamorphic rocks and the foliation is easily seen in the orientation of the mica. Limestone is an essential mineral commodity of national importance.

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

During metamorphism the calcite limestone recrystallizes forming the interlocking calcite crystals that make up the marble. And 2 mechanical transport and deposition of preexisting limestones forming clastic deposits. Both limestone and marble are types of rock made of calcium carbonate residues. Products made with limestone.

Limestone has two origins. Limestone is a sedimentary so it cannot be foliated or non foliated. Metamorphic rocks that do not show foliation are called nonfoliated rocks. Marble is formed from limestone when the limestone is affected by heat and high pressure during a process known as metamorphism.

Some of the many products made using limestone are shown in this photograph. Nonfoliated does not have distinct layers or bands.
