Why does limestone make nonfoliated marble.

Some of the many products made using limestone are shown in this photograph. Limestone is an essential mineral commodity of national importance. 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. Nonfoliated does not have distinct layers or bands.

All are foliated metamorphic rocks and the foliation is easily seen in the orientation of the mica. Limestone has long fascinated earth scientists because of its rich fossil. Breakfast cereal paint calcium supplement pills a marble tabletop antacid tablets high quality paper white roofing granules and portland cement. Limestone is a sedimentary so it cannot be foliated or non foliated.

Metamorphic rocks that do not show foliation are called nonfoliated rocks. 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. The major differences between foliated and nonfoliated metamorphic rocks are in the areas of texture appearance and the type of pressure applied during recrystallization.

One common nonfoliated meta morphic rock is marble which develops from limestone. And 2 mechanical transport and deposition of preexisting limestones forming clastic deposits. 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.

Is marble foliated metamorphic rock or non foliated metamorphic rock. The limestone undergoes metamorhism to slate then phyllite and schist. Limestone vs marble. Limestone has two origins.

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. Marble is a non foliated metamorphic rock.
