explain the used of metamorphic rocks in construction industry?

Answer 1

Here are some examples of metamorphic rocks:
gneiss, slate, marble, schist, soapstone (sometimes called steatite), quartzite + many others

Marble has already been discussed above so lets take a look at the other three.

Gneiss is used as a building stone, but it has also been used in making paving blocks, curbing, and crushed for roads...
It also polishes up nicely and because of the crystal formation formation you get a pattern of banding of the different minerals - beautiful

Slate: floorings, paving, landscaping such as patios, walkways, and fountains, billiard tables, counter tops, fireplaces, tables, and educational chalkboards...

Schist: Because of the high mica content is schist it does not polish up as nicely as gneiss, however it is the source of the
gemstone called garnet. Garnet is a mineral that is nearly always found only in schists, and there are many schists throughout the world in which large crystals of garnet can be found.

Soapstone (steatite) It has its traditional usage of carvings and sculptures but is also used for: stair treads, balusters, sills, island tops, mixing bowls, cookware, cook tops, oven floors, masonry heaters, and fireplace liners

Quartzite: The greatest use of quartzite, as a gem rock, is as a substitute for jade "Indian jade". It is also used for carved signet rings, bookends, candle holders, arrow heads etc - lots of jewelry.

Answer 2

The easiest to explain, and most prolific use of metamorphic rocks in the construction industry, is the use of Marble as counter tops, as flooring, as a facia for commercial buildings, and as signage.

Answer 3

The two most common metamorphic rocks used in building are marble and slate.
Marble, being relatively soft and crystalline can be sawn into slabs used for building stone, benches, flooring stone etc. Although it is relatively soft, it is fairly tough, and does not split easily.
Slate, on the other hand is fissile (it can be split into thin sheets), and is used for all purposes requiring strong, flat material, including roofing, flooring tiles, paving, etc. Slate for roofing tiles is not used as much in new buildings as it was in the past, as ceramic and concrete roofing tiles are now more often used, but it is still used in great quantities for restoration work.
Other metamorphic rocks, as other answerers have noted incluce gneiss (like granite) and quartzite, both used for dimension stone, where strong material suiatble for making strong blocks is required.

Answer 4

There is one mineral that I have noticed the previous answerers have left out. Diamond is actually a metamorphic mineral, and because of its hardness is used in saw blades, industrial drill bits, and anything else that needs to cut very hard substances. Most industrial uses utilize black diamond, not because it's harder--which it's not--but because it has fewer ornamental purposes and is simply less expensive.

Answer 5

marble is used for decorative purposes like coutner tops and floors. Also granite is used for some industrial processes. Some of the stoned buildings in new york are made outo f things like granite too....they sneak up on you but rocks are used out there.....
