Igneous rock:
Igneous rock
or
magmatic rock
, is one of the three main rock types, the others
being sedimentary and metamorphic. Igneous rock is formed through the cooling
and solidification of magma or lava. Typically, the melting is caused by one or
more of three processes: an increase in temperature, a decrease in pressure, or a
change in composition. Solidification into rock occurs either below the surface
as intrusive rocks or on the surface as extrusive rocks. Igneous rock may form
with crystallization to form granular, crystalline rocks, or without crystallization to
form natural glasses.
Metamorphic rock:
Metamorphic rocks arise from the transformation of existing rock types, in a
process called metamorphism, which means "change in form". The original rock is
subjected to heat and pressure, causing profound physical or chemical change. The
protolith may be a sedimentary, igneous, or existing metamorphic rock.They are
classified by texture and by chemical and mineral assemblage. The study of
metamorphic rocks provides information about the temperatures and pressures
that occur at great depths within the Earth's crust. Some examples of metamorphic
rocks are gneiss, slate, marble, schist, and quartzite.
Calcite:
Calcite is a rock-forming mineral with a chemical formula of CaCO3. It is
extremely common and found throughout the world in sedimentary,
metamorphic, and igneous rocks. Some geologists consider it to be a "ubiquitous
mineral" - one that is found everywhere. The properties of calcite make it one of
the most widely used minerals. It is used as a construction material, abrasive,
agricultural soil treatment, construction aggregate, pigment, pharmaceutical and
more. It has more uses than almost any other mineral.
Thank you for watching!
Igneous rocks, formed from magma or lava, and metamorphic rocks, transformed through heat and pressure, are explored alongside calcite, a versatile mineral used in various industries. Discover the beauty and significance of these geological formations.
