The Metamorphic Rock Marble Was Once What Kind Of Rock

When granite is subjected to intense heat and pressure it changes into a metamorphic rock called gneiss.

The metamorphic rock marble was once what kind of rock. Slate is another common metamorphic rock that forms from shale. Metamorphic rocks arise from the transformation of existing rock types in a process called metamorphism which means change in form. Marble metamorphised limestone metamorphic rock. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism.

Gneiss showing layered banding metamorphic rock. In this hand specimen of vermont marble the crystals are small. Serpentinite harzburgite with asbestos metamorphic rock. Usually marble contains other minerals including quartz graphite pyrite and iron oxides.

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. Limestone a sedimentary rock will change into the metamorphic rock marble if the right conditions are met. Marble is a metamorphic rockformed when limestoneis subjected to high pressureor heat. Schist showing foliation folding metamorphic rock.

Under the conditions of metamorphism the calcite in the limestone recrystallizes to form a rock that is a mass of interlocking calcite crystals. Metamorphic rocks are one of three main types. Metachert breccia formed from marine chert metamorphic rock. Marble is a 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. 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 made by regional metamorphism of limestone or dolomite rock causing their microscopic grains to combine into larger crystals. This type of metamorphic rock consists of recrystallized calcite in limestone or dolomite in dolomite rock.

Slate metamorphised shale metamorphic rock. Marble begins as limestone before being subject to the changing process referred to as metamorphism. Metamorphic rocks are rocks that have undergone a change in composition due to intense heat and pressure. The other two primary types of rocks are igneous rocks and sedimentary rocks.
