What rock does limestone belong to?

sedimentary rocksLimestone is a sedimentary rock composed largely of the mineral calcite (calcium carbonate: CaCO3). It often has variable amounts of silica in it, as well as varying amounts of clay, silt, and sand. Limestone rocks fall under the category of sedimentary rocks that are made from mineral calcite.

What are the characteristics of limestone rock?

Limestone is usually gray, but it may also be white, yellow or brown. It is a soft rock and is easily scratched. It will effervesce readily in any common acid.

What is the hardest limestone?

Bell reported in the “Bulletin of Engineering, Geology, and the Environment” that carboniferous limestone consistently rated as harder and stronger than magnesian limestone, inferior oolitic limestone and great oolitic limestone.

How would you describe limestone?

Limestone is a type of carbonate sedimentary rock. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3). A closely related rock is dolomite, which contains a high percentage of the mineral dolomite, CaMg(CO3)2.

Which is more expensive marble or limestone?

Why does Limestone turn green?

When a rock is weathered down over time, the minerals from the rock are dissolved and small pieces are released into the water causing different colors. Iron, manganese and calcium carbonate from limestone are all common minerals that can cause water to range in color from red and orange to green and blue.

What is unique about limestone?

Because limestone contains the remains of dead organisms, it is considered an organic sedimentary rock. There are rare chemical sedimentary rocks that form from the precipitation of calcium carbonate from ocean water. … Limestone turns into the metamorphic rock marble when subjected to high amounts of pressure and heat.
