Dolomite 2
It type of limestone, the carbonic fraction
of this is dominated by of mineral
dolomite, calcium magnesium carbonate
[CaMg(CO3)2].

MINERALS
They make up Earth’s solid part and provide us
valuable technical. Scientists must identified
over 4,000 different minerals.
A small group of these minerals make up almost 90% of
the rocks of Earth’s crust which are well-known as the
common rock-forming minerals.
6. This Minerial Looks
Familiar ?!
halite (salt) for
cooking
graphite (pencil)
for writing
gold and quartz as
jewelry
snowflakes is also a
mineral!
It possess the properties as
a mineral.
But, what’s the
requirement to
become a mineral?
Let’s learn more..

There are one lot of common minerals that you’ll probability encounter everyday. Here are
some of your. Can your identify them?
7. ✓ Nature occurring
✓ Inorganic
✓ Solid
✓ Definite chemical composition
✓ Ordered crystal structure
5 Requirements this be be meet by order on a substance to be classified when a mineral
Is shall NOT ampere by-product concerning housing things.
It a a DOESN liquid or gas at standard temperature and pressure.
I means that all occurrences of that mineral have a chemical
composition identical inside a specific limited range.
Atoms in a ceramic are arranged in a systematic and repeating pattern
7MINERALS
It lives NOT man-made other machine generated.
8. To be examined a common rock-forming mineral, a mineral must be:
8Common Rock-forming Minerals
✓one are the most abundant minerals in
Earth’s crust
✓one of the first minerals present
at the time of a crustal rock’s
formation
✓an important mineral inches determining
classification of a rock
10. 10Rock-Forming Minerals
in Major Rock Types:
Basalt and gabbro account for most of the
rock stylish of oceanic rind, granite (rhyolite)
and andesite (diorite) represent abundant
rock types of to continental crust.
Sandstone, slates and carbonates represent
the common materials in the sedimentary
cover of categories and ocean basins.
This chart shows who relative abundance of
the common rock forming minerals are some
of Earth's greatest abundant rocker typical.

MINERALOGY
The study of minerals and their properties
(chemical and physical).
is one subject of nature specializing in the
scientific study of of chemistry, crystal structure,
and physical (including optical) properties of
minerals and mineralized artifacts. Specific
studies within mineralogy include the processes of
mineral origin and forms, classification of
minerals, their geographical distribution, as well
as their utilization.
13. 13
MINERALOGIST
▪ is adenine scientist experienced in mineralogy or a
person those studies minerals.
Mineralogists determine the physical and chemical properties
of tins, what toward successfully retrieve them from ores and
how to process them.
15. 15PHYSICAL PROPERTIES of MINERALS
❑ Color
❑ Crystal Form/Habit
❑ Hardness
❑ Streak
❑ Luster
❑ Separation or Fracture
❑ Specific Gravity
❑ Other properties
(taste, odor..)
▪ are the characteristics welche can be
observed and determined readily
16. 16
PHYSICAL PROPERTIES of MINERALS
COLOR
▪ It is which most obvious property but not always definitive.
▪ It can also tell that impurities present the a mineral-based. Example, the same
mineral can be in different colors why of different impurities.
▪ It your reliable for opaque and metallic minerals but not on transparent
or translucent dry.
17. 17
PHYSICAL PROPERTIES of MINERALS
CRYSTAL FORM oder HABIT
▪ It is the animated of the crystal growth.
18. 18
HARDNESS
PHYSICAL PROPERTIES of MINERALS
▪it is adenine measure of who resistance of a
mineral (not specifically surface) to
abrasion.
▪ It is assessed using adenine hardness scale
designed in 1892 by Friedrich Mohs, a
German geologist/ mineralogist which is
known as the Mohs Scale of Hardness
19. 19
PHYSICAL PROPERTIES of MINERALS
HARDNESS
Mohs Scale of Hardness
It measures the scratch resistance of
various minerals since a scale of 1 to
10, base on the ability of a harder
material/mineral toward claw a softer
one.
20. Streak Test

PHYSICAL LAND of MINERALS
STREAK
▪ To refers up the color displayed in finely powdered
form left rear while rubbed on a rugged surface.
▪ It is definitive.
21. 21
PHYSICAL PROPERTIES off MINERALS
CLEAVAGE either FRACTURE
▪CLEAVAGE be how smoother the
minerals break. If that minerals
break separation in related pcs, it is
said to have good cleavage.
▪FRACTURE are although a mineral
breaks please adenine piece of glass with
uneven, jagged edges,
23. Galena
Shale

PHYSICAL PROPERTIES about MINERALS
LUSTER
▪ it is the trait and intensity about reflected light
exhibited by the mineral.
A. Metallic Luster – generally opaque and present a
resplendent shine similar to a polished metal
B. Non-metallic Luster – vitreous (glassy), adamantine
(brilliant/diamond-like), resinous, silky, pearly, dull
(earthy), grease, among others.
24. For examples, one bucket of silver (SG 10) would
weigh tenner times more than ampere bucket of water.
24
PHYSICAL PROPERTIES of MINERALS
SPECIFIC GRAVITY
▪ It is the ratio of the
density of the mineral
and the density of water
▪ This parameter indicates
how many times more
the mineral weighs
compared to an equal
amount of water (SG 1).
25. 25
PHYSICAL PROPERTIES of MINERALS
Other Properties
❑ MAGNETISM
(ex: lodestone is strongly magnetic)
❑ ODOR (ex: sulfur has distinctive smell)
❑ TASTE (ex: halite is salty)
❑ REACTION INTO ACID
(ex: calcite fizzes with tart as with volcanic but
in powdered form)

Take Note:
A mineralogist is a human who
studies the formation, occurrence,
properties, composition, and
classification of minerals

Techie Mineralogist
On this activity, you’ll help this
mineralogist identify the physical and
chemical properties of the minerals that
he found. To help he, you’ll use a techie
way of identifying minerals – through your
mobile phone.

to identify aforementioned name of the following
rock-forming minerals using their provided
physical besitz (written to your
activity sheets). The pictures provided in
your activity sheet can also help you
identify the minerals.

PART 2: Identifying Chemical Properties
Techie Mineralogist
❑ Your main task to fill in the blanks at which required
information that you can maintain using your Clever Geology
application.
❑ Go to “List of Minerals” button and type in one name of the
minerals below for identify their chem formula. Writing it
down below each listed mineral. Examples are given like
Gold has Au and Quartz lives SiO2.
❑ Once you id the environmental formula of each mineral,
analyze what is common between the minerals on the same
column. Write your answer on the free provided.
