The main difference between the two is that marble is a metamorphic rock, while limestone is a sedimentary rock. Sedimentary rock is formed from minerals and particles – limestone is usually formed under water, which is why it often has shells, sand or mud particles in it.
Sandstone is created from particles of other rocks and sand. It is not as dense as limestone and is used as raw material for many industries. Telling the difference between these two types of rock can be accomplished just by looking at their physical attributes.

Dec 12, 2013· Calcium carbonate does have (at least) two crystal forms (aragonite and calcite), but I think limestone, chalk and marble are all calcite. I think the difference is due to particle size, how well formed the crystals are and what impurities are present.
Chalk is a type of limestone, there are several types of limestone, chalk, crystalline, fossiliferous, oolitic, travertine and a few others. What is the relationship between limestone marble and ...
Marble and limestone lie at the opposite end of the hardness scale from granite.

Apr 25, 2017· Limestone is a sedimentary rock composed mainly of calcium carbonate (CaCO3). However, it can also contain magnesium carbonate, clay, iron carbonate, feldspar, pyrite and quartz in minor quantities, according to the Encyclopaedia Britannica. Most types of limestone have a granular texture. Often, the grains are ...
As nouns the difference between limestone and chalk is that limestone is (mineralogy) an abundant rock of marine and fresh-water sediments; primarily composed of calcite (caco₃); it occurs in a variety of forms, both crystalline and amorphous while chalk is (uncountable) a soft, white, powdery limestone. As a adjective limestone is made of or with limestone.
Marble is made of calcium carbonate, CaCO3, which is also what limestone is made from. The only difference between limestone and marble is the crystalline structure. Limestone crystals are much smaller than that of marble, and limestone is much more porous. Marble and limestone are common building materials due to their durability.
Feb 21, 2009· Chalk is a variety of limestone that has a very uniform texture. When limestone is metamorphosed by high heat and pressure, it becomes marble. The metamorphism increases the hardness, on the Moh's hardness scale, and changes the texture significantly.
