Marble is commonly used for sculpture and as a building material. Marble forms under such conditions because the calcite forming the limestone recrystallises forming a denser rock consisting of roughly equigranular calcite crystals. The dominant minerals in granite s are resistant to chemicals that you would find in a residential setting but may have minerals that are vulnerable to certain acids. 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.

Some have specks of various colours including green gold and brown. The variety of colours exhibited by marble are a consequence of minor amounts of impurities being incorporated with the. Granite coarse or medium grained intrusive igneous rock that is rich in quartz and feldspar. Petrographically marbles are massive rather than thin layered and consist of a.

Still harder than marble its black colour comes from its dominant minerals namely plagioclase and pyroxene. 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. What is the main factor that causes contact metamorphism. Black granite may have whitish linear patterns or tiny specks that resemble stars in the night sky galaxy.

Marble is formed from limestone. Marble marble is a metamorphic rock formed when limestone is exposed to high temperatures and pressures. Pyrite sphalerite and galena. What minerals from hydrothermal metamorphism are formed at black smokers.

Limestone and dolomite are also in the carbonate mineral group. Black granite is made of gabbro rock. Commercially it includes all decorative calcium rich rocks that can be polished as well as certain serpentines verd antiques. 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.
