Is Marble Metamorphic

Some kinds of metamorphic rocks granite gneiss and biotite schist are two examples are strongly banded or foliated.

Is marble metamorphic.

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. Limestone a sedimentary rock will change into the metamorphic rock marble if the right conditions are met. In this hand specimen of vermont marble the crystals are small. Which one of the following is an example of metamorphic rocks a marble b sandstone c granite d basalt 2 see answers k60321653 k60321653 explanation.

Marble is a granular metamorphic rock it is derived from limestone or dolomite and it consists of a mass of interlocking grains of calcite or the mineral dolomite. Although metamorphic rocks typically form deep in the planet s crust they are often exposed on the surface of the earth. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. 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 under the conditions of metamorphism the calcite in the limestone recrystallizes to form a rock that is.

This type of metamorphic rock consists of recrystallized calcite in limestone or dolomite in dolomite rock. Slate is another common metamorphic rock that forms from shale. 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.

Form of it when limestone buried deep in the older layers of earth s crust is subjected to heat and pressure from thick layers of overlying sediments. The preexisting rocks may be igneous sedimentary or other metamorphic rocks. Metamorphic rock any rock that results from the alteration of preexisting rocks in response to changing conditions such as variations in temperature pressure and mechanical stress and the addition or subtraction of chemical components. Option a marble.

Marble is made by regional metamorphism of limestone or dolomite rock causing their microscopic grains to combine into larger crystals. Non foliated metamorphic rocks such as hornfels marble quartzite and novaculite do not have a layered or banded appearance. Some examples of metamorphic rocks are gneiss slate marble schist and quartzite. Foliated means the parallel arrangement of certain mineral grains that gives the rock a striped appearance.
