Why do we study rock forming minerals?
Minerals occurring within a rock in small quantities are referred to as “accessory minerals”. Although accessory minerals are present in only small amounts, they may
provide valuable insight into the geological history of a rock
, and are often used to ascertain the age of a rock.

Having a knowledge of minerals and rocks is
the first important step to better manage Earth’s resources
and is important to our health and environment. To be a mineral, a material must be a naturally occurring, inorganic solid with a definite internal structure (crystalline), and a definite chemical composition.
What is importance of rocks?

olivine, augite, hornblende, biotite, calcium-
rich plagioclase (anorthite), sodium-rich plagioclase (albite), potassium-rich feldspar (commonly orthoclase), muscovite, quartz, and calcite.
What can rocks tell us?
Rocks tell us a
great deal about the Earth’s history
. Igneous rocks tell of past volcanic episodes and can also be used to age-date certain periods in the past. Sedimentary rocks often record past depositional environments (e.g deep ocean, shallow shelf, fluvial) and usually contain the most fossils from past ages.
What is the study of rocks and fossils called?
