What's the difference between limestone and marble:
1. Different causes
Limestone is formed mainly in shallow seas.Limestone can be divided into granular limestone (water transport, sedimentary formation).Biological skeleton limestone and chemical and biochemical limestone.
Marble is a metamorphic rock formed by the action of high temperature and high pressure in the crust.
2. Different main USES
Lime and limestone are a large number of building materials, industrial raw materials.Limestone can be directly processed into stone and fired into quicklime.The main component of hydrated lime is Ca(OH)2. The hydrated lime is prepared into lime paste, lime plaster, etc. It is used as coating material and brick adhesive.
Marble is mainly used for processing into various forms of material, plate, for the building wall, ground, Taiwan, column, also often used in memorial buildings such as stele, tower, statue and other materials.Marble can also be carved into arts and crafts, stationery, lamps and lanterns, utensils and other practical art.
3. Different resource distribution
Limestone distribution: China is one of the countries rich in limestone mineral resources in the world.According to the former national bureau of building materials geological center statistics, the national limestone distribution area of 438,000 KM2, accounting for 1/20 of the land area, which can be used for cement raw materials limestone resource volume of the total resource volume of 1/4 ~ 1/3.
Marble distribution: after 2000 marble mining the most active to belong to Asia.From Mongolia black from Inner Mongolia to yachu red from hainan province;From liaoning dandong green to xinjiang tianshan blue, stone storage is very rich, the name of special varieties in the world's forefront.The country has built more than 3,000 mining sites, varieties up to 1,000.
A brief introduction to limestone tile products：
Usually when the limestone is cut, it is found that there are intact or damaged fossils inside the stone.Unless limestone forms a reef, limestone from the sea generally has a layered structure.The tissue may be dense or have granular pores.
