IGNEOUS and in mountain building, having them

IGNEOUS ROCKS

Igneous rocks are made from the
solidification from either a quick or a slow means of cooling magma or lava.
Here are some of these examples:

1.      Granite

 

 

Abundant
and termed as the most widespread type or example of igneous rocks, granites are
easily and commonly found within the continental crust of the Earth i.e.
volcanic arc and in mountain building, having them as the result of that
collision. Mainly composed of feldspar, mica, and quartz minerals, it is
compressive that lies within 200MPa and a Mohs harness rating at seven a given
measurement onto the density and hardness of a rock one may conclude that they
resistant to damage and is considered a hard stone able to withstand from
scratches or cracks for your countertops, however, they are vulnerable to
staining. They are coarse-grained, light hued i.e. predominantly pink or gray
in color, and are easy to spot on.

Granite
dimension stones are used as aggregates, as they are ideal for concrete
aggregate for their high content of silica, for infrastructures, bridges, and
many exterior projects. When cut and polished, they are mostly used as
countertops or for any interior design and at some times for the façade of a
building. And when cut and carved, they are mainly used as headings, statues or
monuments. The following photos illustrates its function:

 

2.     
Pumice

 

 

Rocks that forms during the eruption of a volcano, a product
of lava with the abundant presence of water and gases, pumice is definitely
light-weight compared to other rocks. Oftentimes referred to as pumicite, it is
a coarse-grained highly vesicular volcanic glass and are usually found by the
beaches, as they were formed either by the sea or ocean. As rated by the Mohs
scale to be 6 by its strength, it is relatively strong yet should its deposit
come on land, they are abundant, having perhaps acres of land unable to produce
crops, liken of the events taken once by 1958 at Wright’s Creek Area and is not
wind resistant. Also abundant, they are stones with minute holes making them
light-weighted and are light hued.

With the amount of pumice considerably large, they are often
times used as a substitute as lightweight aggregate rather than of making
building blocks, making the construction materials cheaper.  Other benefits from this rock would be of
using it as facing stone, garden decoration and paving stone, while in the
interior it could be used as decorative aggregates, flooring and interior
decoration. The following photos illustrates its function:
