Is Marble A Foliated Metamorphic Rock
The rock on the left formed from granite.
Is marble a foliated metamorphic rock. Marble is a metamorphic rock composed of recrystallized carbonate minerals most commonly calcite or dolomite. Marble is metamorphosed limestone. Marble is a non foliated metamorphic rock that forms through the metamorphism of limestone. The specimen shown above is about two inches five centimeters across.
Which statement about the rocks is accurate. Quartzite is made of metamorphosed sandstone while marble is formed from limestone that was metamorphosed. Due to geological changes a metamorphic rock of the foliated or nonfoliated type will be created. Marble is a non foliated metamorphic rock that is produced from the metamorphism of limestone or dolostone.
Common metamorphic rocks include phyllite schist gneiss quartzite and marble. Both foliated and nonfoliated rocks begin their lives as either sedimentary igneous or another metamorphic rock. These geological changes can be due to heat and temperature from the recrystallizing rock being found deep within the earth s crust. In geology the term marble refers to metamorphosed limestone but its use in stonemasonry more broadly encompasses unmetamorphosed limestone.
These are two metamorphic rocks. It is composed primarily of calcium carbonate. Slate is another common metamorphic rock that forms from shale. Different types of rocks and minerals can form non foliated metamorphic rocks.
When granite is subjected to intense heat and pressure it changes into a metamorphic rock called gneiss. The rock on the right has randomly arranged grains. Hornfels have no specific composition while amphibolites are formed from hornblende and plagioclase. The rock on the right is foliated.
The rock on the left is formed from cooled magma. Limestone a sedimentary rock will change into the metamorphic rock marble if the right conditions are met. Nonfoliated metamorphic rocks are identified on the basis of their composition. Quartzite composed of the mineral quartz.
When it forms the calcite crystals tend to grow larger and any sedimentary textures and fossils that might have been present are destroyed. Marble composed of the mineral calcite. Some examples of non foliated metamorphic rocks are marble quartzite and hornfels.
