Marble Is A Foliated Metamorphic Rock

Changes in rocks caused by magma seeping into crustal rock.

Marble is a foliated metamorphic rock.

Which statement about the rocks is accurate. Both foliated and nonfoliated rocks begin their lives as either sedimentary igneous or another metamorphic rock. Occurs at high temperature and low pressure 6. The rock on the right has randomly arranged grains.

Changes in rocks caused by tectonic plates rubbing sideways against one another. 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. 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 typically not foliated although there are exceptions.

Occurs at low to high temperatures and high pressure 3. Marble is a non foliated metamorphic rock that is produced from the metamorphism of limestone or dolostone. Marble composed of the mineral calcite. Marbles are the type of metamorphic rock that results.

Physical chemical or structural change. These geological changes can be due to heat and temperature from the recrystallizing rock being found deep within the earth s crust. It is composed primarily of calcium carbonate. Quartzite composed of the mineral quartz.

The specimen shown above is about two inches five centimeters across. 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. The rock on the right is foliated. Quartzo feldspathic rocks that contain an abundance of quartz and feldspar fall into this category.

Nonfoliated metamorphic rocks are identified on the basis of their composition. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. The rock on the left is formed from cooled magma. 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.

Protoliths are usually granites rhyolites or arkose sandstones and metamorphism results in gneisses containing an abundance of quartz feldspar and biotite. Marble is a metamorphic rock composed of recrystallized carbonate minerals most commonly calcite or dolomite. Metamorphic rocks arise from the transformation of existing rock types in a process called metamorphism which means change in form. These are two metamorphic rocks.
