Marble Is A Foliated Metamorphic Rock

Changes in rocks caused by tectonic plates rubbing sideways against one another.

Marble is a foliated metamorphic rock.

The original rock is subjected to heat temperatures greater than 150 to 200 c and pressure 100 megapascals 1 000 bar or more causing profound physical or chemical change the protolith may be a sedimentary igneous or existing metamorphic rock. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. Metamorphic rocks arise from the transformation of existing rock types in a process called metamorphism which means change in form. Due to geological changes a metamorphic rock of the foliated or nonfoliated type will be created.

Which statement about the rocks is accurate. Changes in rocks caused by magma seeping into crustal rock. Physical chemical or structural change. Nonfoliated metamorphic rocks are identified on the basis of their composition.

Occurs at high temperature and low pressure 6. These geological changes can be due to heat and temperature from the recrystallizing rock being found deep within the earth s crust. Quartzo feldspathic rocks that contain an abundance of quartz and feldspar fall into this category. Occurs at low to high temperatures and high pressure 3.

These are two metamorphic rocks. In geology the term marble refers to metamorphosed limestone but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. Both foliated and nonfoliated rocks begin their lives as either sedimentary igneous or another metamorphic rock. Sandstone is defined as a rock which is composed of sand sized grains of various minerals mostly of uniform size and often are smooth and rounded.

It is composed primarily of calcium carbonate. Protoliths are usually granites rhyolites or arkose sandstones and metamorphism results in gneisses containing an abundance of quartz feldspar and biotite. Layers or bands found in metamorphic rock 1. The rock on the left formed from granite.

The rock on the right is foliated. The rock on the right has randomly arranged grains. It is composed primarily of the mineral calcite caco 3 and usually contains other minerals such as clay minerals micas quartz pyrite iron oxides and graphite. Marble is a metamorphic rock composed of recrystallized carbonate minerals most commonly calcite or dolomite.

The specimen shown above is about two inches five centimeters across. The rock on the left is formed from cooled magma. Marble is typically not foliated although there are exceptions. Marbles are the type of metamorphic rock that results.

Marble is a non foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time.
