The difference between marble and lapis lazuli

The main differences are, the formation of different, different components, different applications, as follows:

One, the formation of different

1, marble

Marble is the original rock in the earth's crust through the crust of the formation of high temperature and high pressure action of metamorphic rocks, the crust of the role of the internal forces prompted by the original types of rocks to qualitative changes in the process.

2, lapis lazuli

Lapis lazuli is the most widely distributed in the Earth's crust of a gray or gray-white sedimentary rocks generated in the Sea-Lake Basin (accounting for about 15% of the lithosphere), is the most important component of carbonate rocks.

Two, the composition is different

1, marble

Marble is mainly composed of calcite, limestone, serpentine and dolomite, its main component is calcium carbonate-based, accounting for more than 50%. Other magnesium carbonate, calcium oxide, manganese oxide and silica.

2, lapis lazuli

Lapis lazuli is mainly leopard skin chert. Light gray - gray-yellow, fresh surface is brownish yellow and gray, local maroon, the matrix is gray, mostly fine powder diameter crystal calcite.

Three, different applications

1, marble

Mainly used for processing into a variety of shapes, plates, for the building walls, floors, platforms, columns, but also commonly used in monumental buildings, such as monuments, towers, statues and other materials. Marble can also be carved into arts and crafts, stationery, lamps, utensils and other practical works of art.

2, lapis lazuli

Lapis lazuli cut by stonemasons from the deep cut into slabs widely used in living room table tops, or cabinet counters and so on.

Lime stone is the raw material of lime. In addition to lime, lapis lazuli is also mined by stone factories for stone, dashi. Stone was used as a component of cement and dashi became necessary for building houses.

Lapis lazuli is also mainly used for the crushing of river pebbles, cobbles, granite, limestone, marble, boulders, and many other hard stones. Widely used in highways, high-speed railroads, country roads, construction sand and many other fields, lapis lazuli is an ideal material for the construction industry.
