Limestone can be metamorphosed into marble through the process of recrystallization under high pressure and temperature conditions. The calcite crystals in limestone are transformed into interlocking crystals of calcite or dolomite in marble, resulting in increased hardness and a distinctive pattern and coloration.

What rock is formed when limestone is metamorphosed?
Marble is formed when limestone is metamorphosed. This process occurs when the mineral calcite in limestone recrystallizes due to heat and pressure, resulting in a denser, harder rock with a crystalline structure.
What are limestone caves?
Limestone caves are formed by the dissolution of limestone rocks over thousands of years due to the chemical reaction of rainwater and carbon dioxide. This process creates underground caverns and passages with unique formations such as stalactites and stalagmites. Limestone caves are often popular tourist attractions due to their natural beauty and geological significance.
What kind of rock was the pyramid's in Egypt made of?
The pyramids in Egypt were primarily made of limestone blocks. These limestone blocks were quarried from nearby sources and were used to construct the outer casing of the pyramids.
What type of rock is usually present in areas with a lot of caves?
Limestone is the type of rock that is commonly found in areas with a lot of caves. Limestone is made of calcium carbonate, which is soluble in water. Over time, as rainwater seeps into the ground, it dissolves the limestone and creates openings and caves in the rock.
Why are limestone caves so common?
Limestone caves are common because limestone is a soluble rock that dissolves easily in water. Over time, groundwater flowing through cracks in the limestone gradually enlarges these passages to form caves. Additionally, limestone is often found in areas with karst topography, characterized by sinkholes, underground rivers, and other features that promote the formation of caves.
Is limestone a marble?
Marble is metamorphosed limestone.
What rock is formed when limestone is metamorphosed?
Marble is formed when limestone is metamorphosed. This process occurs when the mineral calcite in limestone recrystallizes due to heat and pressure, resulting in a denser, harder rock with a crystalline structure.
Which rocks are metamorphic rocks?
Marble (metamorphosed limestone) Slate (metamorphosed shale) Gneiss (metamorphosed granite)
How are limestone and marble related?
Marble is metamorphosed limestone or dolostone.
Is marble polished limestone?
No. Marble is metamorphosed limestone, recrystallized from heat, pressure, or both.
How do rocks such as limestone and marble form?
Limestone - sedimentary deposition of calcarious marine organisms. Marble - compressed (metamorphosed) limestone.
Is marble a metomorphic rock?
Yes, marble is metamorphosed limestone.
Is marble an intrusive rock?
No, marble is a metamorphosed limestone, which itself is a sedimentary rock.
What is the hardness of the Metamorphic rock?
Depends on which one. Diamond is a metamorphosed coal/carbon that is the hardest natural substance known. Marble is metamorphosed limestone that is much softer. It's safe to say that all metamorphosed rocks are harder than they were in their pre-metamorphosed form.
Where does marble rock come from?
Marble rock is derived from limestone that has been subjected to high heat and pressure within the Earth's crust. This metamorphic process causes the limestone to recrystallize into marble, resulting in its characteristic appearance and durability. Marble is typically found in mountainous regions where tectonic forces have caused these high temperatures and pressures to occur.
Is there anything unusual about marble?
There are many different types of marble. Marble is limestone that has been metamorphosed.
A metamorphic rock made from limestone?
Marble is a metamorphic rock formed from limestone that has undergone intense heat and pressure deep within the Earth's crust. The process of metamorphism recrystallizes the original minerals in limestone to create the distinct crystalline structure and smooth texture of marble. Marble is valued for its beauty and is commonly used in architecture and sculpture.
