Parent Rock For Marble
Marble is composed of interlocking calcite grains.
Parent rock for marble. Being slightly porous light can penetrate the marble and make it sparkle. There is a lot of variation in the color and texture of marble. The limestone or parent rock undergoes chemical changes during metamorphism called recrystalization and makes marble. Marble is formed by the metamorphosis of limestone by heat and pressure.
Depending on the composition of the marble rock it can be one or both of the parent rocks that. Therefore limestone may be called the parent rock or more correctly the protolith of marble. 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. The two main influences are the kind of limestone that makes up the parent rock and the kind and degree of metamorphism.
Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. The parent rocks of marble are limestone and dolomite. 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.
