Marble Is A Metamorphic Rock That Forms From

Marble is a rock resulting from metamorphism of sedimentary carbonate rocks most commonly limestone or dolomite rock.

Marble is a metamorphic rock that forms from.

The rock on the left formed from granite. The rock on the right has randomly arranged grains. In its pure form marble is a white stone with a crystalline and sugary appearance consisting of calcium carbonate caco 3. A granite b limestone c sandstone d shale e basalt.

1 marble is a metamorphic rock that forms from a protolith. Nonfoliated metamorphic rocks such as marble and quartzite derived their metamorphism more from heat than from directional pressure. Although metamorphic rocks typically form deep in the planet s crust they are often exposed on the surface of the earth. Usually marble contains other minerals including quartz graphite pyrite and iron oxides.

Metamorphic rock forms from pre existing rock when heat and pressure cause solid state transformations. Foliations form at right angles to intense directional. Limestone a sedimentary rock will change into the metamorphic rock marble if the right conditions are met. Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat.

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. Which statement about the rocks is accurate. Metamorphism causes variable recrystallization of the original carbonate mineral grains. Marble is made by regional metamorphism of limestone or dolomite rock causing their microscopic grains to combine into larger crystals.

These are two metamorphic rocks. In this hand specimen of vermont marble the crystals are small. These minerals can give marble a pink brown gray green or variegated coloration. The rock on the left is formed from cooled magma.

The rock on the right is foliated. The resulting marble rock is typically composed of an interlocking mosaic of carbonate crystals. Slate is another common metamorphic rock that forms from shale.
