Why Does Limestone Make Nonfoliated Marble

Limestone is a sedimentary so it cannot be foliated or non foliated.

Why does limestone make nonfoliated marble.

Limestone vs marble. Limestone has long fascinated earth scientists because of its rich fossil. Marble is a non foliated metamorphic rock. Nonfoliated does not have distinct layers or bands.

Metamorphic rocks that do not show foliation are called nonfoliated rocks. Is marble foliated metamorphic rock or non foliated metamorphic rock. Products made with limestone. And 2 mechanical transport and deposition of preexisting limestones forming clastic deposits.

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. One common nonfoliated meta morphic rock is marble which develops from limestone. Travertine tufa caliche chalk sparite and micrite are all varieties of limestone.

The major differences between foliated and nonfoliated metamorphic rocks are in the areas of texture appearance and the type of pressure applied during recrystallization. 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. Marble is formed from limestone when the limestone is affected by heat and high pressure during a process known as metamorphism.

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. 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. 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. Limestone has two origins.
