Marble parent rocks.

The original rock type was limestone. Learn vocabulary terms and more with flashcards games and other study tools. Marble is commonly used for sculpture and as a building material. The original rock that was metamorphosed is usually referred to as the parent rock or protolith.

In the rock cycle there are three different types of rocks. Sedimentary igneous and metamorphic. Limestone is mostly calcite or calcium carbonate caco 3 dolomite camg co 3 2 is related to limestone but is rich in magnesium. Marble is a common building and ornamental stone.

An example is seen when we take the parent rock limestone which is a sedimentary rock and expose it to heat and pressure to make marble. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. Marble granular limestone or dolomite i e rock composed of calcium magnesium carbonate that has been recrystallized under the influence of heat pressure and aqueous solutions. Because the parent rock limestone is composed of calcite marble with also react to and dissolve in acids.

Rocks that undergo a change to form a new rock are referred to as metamorphic rocks. Sedimentary and igneous rocks began as something other than rock. 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. Instead it is a rock type that forms when an existing rock is metamorphosed.

Marble is a metamorphic rock that comes from metamorphosed limestone or dolomite. Hornfels is not a rock that is deposited. Sedimentary rocks were originally sediments which were compacted under high pressure. 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.

There is a lot of variation in the color and texture of marble. Marble has a uniform texture non foliated. 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. Parent rocks and protoliths.

Commercially it includes all decorative calcium rich rocks that can be polished as well as certain serpentines verd antiques. Petrographically marbles are massive rather than thin layered and consist of a. Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat.
