Can Marble Be Foliated

Examples of foliated metamorphic rocks would be schist gneiss and slate.

Can marble be foliated.

Foliation is more easily seen on a microscopic scale rather than in hand specimen. The minerals in the rock are aligned and look platey or banded according to how pressure was applied to the rock during that phase. Non foliated metamorphic rocks such as hornfels marble quartzite and novaculite do not have a layered or banded appearance. When there are more minerals the alignment is more obvious as the rock appears layered.

Although it is still used for making statures this rock can also be. Marble was considered one of the most beautiful and useful rocks throughout history. Marble is a metamorphic rock composed of recrystallized carbonate minerals most commonly calcite or dolomite marble is typically not foliated although there are exceptions in geology the term marble refers to metamorphosed limestone but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. In its pure form marble is a white stone with a crystalline and sugary appearance consisting of calcium carbonate caco 3 usually marble contains other minerals including quartz graphite pyrite and iron oxides these minerals can give marble a pink brown gray green or variegated coloration.

Marble is commonly used for sculpture and as a building material. Even calcite crystals realign. Foliated metamorphic rocks such as gneiss phyllite schist and slate have a layered or banded appearance that is produced by exposure to heat and directed pressure. Marble will not show noticeable foliation although it undergoes some pressure during metamorphism.

It is because they are made of only one mineral.
