BLOOD FROM A STONE: SOCIAL AND E 2
INTRODUCTION
Granite is a type of common rock of felsic intrusive igneous plutonic rock which is
phaneritic and granular in texture. This type of rock can be predominantly grey, pink or white in
color and these colors are conspicuous enough to be seen with unaided eyes. Granite is formed
from the slow crystallization of magma under the surface of the earth thus they are known as
plutonic. Some of the key characteristics of this type of rock include durability and strength. The
word granite (granum in Latin) means grain thus this rock is full of small and large crystal
grains. This type of rock can withstand a higher temperature of about 1200 degrees Fahrenheit.
Graphite is a scratch-proof rock, thus it will not scratch even after being cut. The diagram below
illustrates Granite rock;

Because of the strength, aesthetic appearance and durability of granite, this rock is used in the
construction of monuments, as jewelry, used in bathroom skins, tabletops, and shelves.

Procedures
Granite formation is a complicated process that can be understood through tectonic
plates. The granite is formed at the convergent boundary of plates where subduction is
happening. Subduction is where one plate is downwardly plunged under the other one
(Johannes, 2012). Basically, this rock is formed through two processes. The first process is
where the subducting plate will divide the earth to earth's mantle which heats up and starts to
melt. At this point, magma will be created, rise and resulting in the melting of rock which makes
more magma. When the formed magma cools it forms other igneous rocks such as diorite but not
granite (Haldar, 2013). In the second process magma formation, subduction and melting
continue. Nevertheless, in case the magma is formed in this step, it rises upwards, this results in
part of the diorite formed in the first process to start melting (Chen, 2017). The formed diorite
will combine with the surrounding melting sedimentary rocks and igneous rocks which makes
magma to cool and form granite. These formation processes occur in the earth's crust which is
always found in the mountainous regions, the formation occurs on the land. The above formation
process can be illustrated visually as below;
