It is composed primarily of the mineral calcite caco3 and usually contains other minerals such as clay minerals micas quartz pyrite iron oxides and graphite.
Limestone into marble.
Limestone change into marble when a great heat and pressure come from the under of the earth change into marble.
When limestone is heated to a high temperature and squeezed at the base of a mountain it recrystallizes into the metamorphic rock marble marbles are fairly dense relatively easy to cut or be shaped into blocks and some forms are white in colour.
Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism.
Because marble is a fairly soft material only a three on the mohs hardness scale it is easy to cut and carve.
When the heat and pressure hits the limestone calcite seed crystals form.
Limestone is hard enough to resist weathering but usually soft enough to be worked cut and carved by stonemasons.
When rocks are formed limestone is heated and squeezed which causes the grains to recrystallize.
Marble on the other hand is a rock formed when limestone recrystallizes into marble during the mountain building process.
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.
It is metamorphic and is usually used as building material and in sculptures.
Marble is commonly used for sculpture and as a building material.
Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism.
