COLOR
The way a mineral interacts
with light
Some minerals always have
the same color
Some minerals have a range
of colors

STREAK
The color of the powder
produced by the mineral
Determined by scraping
mineral across a ceramic
plate

Luster
The way a mineral scatters
light
Distinguish between
metallic and non metallic

Hardness
Measure of a mineral’s
ability to resist scratching
Represents the strength of
the bonds
Hard minerals can scratch
soft minerals, but soft
minerals cannot scratch
hard ones
![Page 13: IDENTIFYING MINERALS - Weeblymrswelsing.weebly.com/.../identifying_minerals.pdf · IDENTIFYING MINERALS Author: Melissa Created Date: 11/22/2013 12:25:15 PM](https://reader034.vdocuments.site/reader034/viewer/2022043006/5f917e5bd5fed2589061b6be/html5/thumbnails/13.jpg)
Mohs Hardness Scale : 1 -10
1 =
10 = Diamond –
hardest
Talc -
softest

Crystal Habit
Preferred crystal shape that
forms when a mineral grows
unimpeded
![Page 15: IDENTIFYING MINERALS - Weeblymrswelsing.weebly.com/.../identifying_minerals.pdf · IDENTIFYING MINERALS Author: Melissa Created Date: 11/22/2013 12:25:15 PM](https://reader034.vdocuments.site/reader034/viewer/2022043006/5f917e5bd5fed2589061b6be/html5/thumbnails/15.jpg)

Breakage
How a mineral breaks
depending on the
arrangement of atoms
2 types:
Cleavage
Fracture
![Page 17: IDENTIFYING MINERALS - Weeblymrswelsing.weebly.com/.../identifying_minerals.pdf · IDENTIFYING MINERALS Author: Melissa Created Date: 11/22/2013 12:25:15 PM](https://reader034.vdocuments.site/reader034/viewer/2022043006/5f917e5bd5fed2589061b6be/html5/thumbnails/17.jpg)
Cleavage: mineral breaks along
weak bonds and forms distinct
flat, smooth (planar) surfaces
![Page 18: IDENTIFYING MINERALS - Weeblymrswelsing.weebly.com/.../identifying_minerals.pdf · IDENTIFYING MINERALS Author: Melissa Created Date: 11/22/2013 12:25:15 PM](https://reader034.vdocuments.site/reader034/viewer/2022043006/5f917e5bd5fed2589061b6be/html5/thumbnails/18.jpg)

Fracture: when bonding is
equally strong in all directions,
mineral breaks in an irregular
or curved way
![Page 20: IDENTIFYING MINERALS - Weeblymrswelsing.weebly.com/.../identifying_minerals.pdf · IDENTIFYING MINERALS Author: Melissa Created Date: 11/22/2013 12:25:15 PM](https://reader034.vdocuments.site/reader034/viewer/2022043006/5f917e5bd5fed2589061b6be/html5/thumbnails/20.jpg)
Specific Gravity
The density of a mineral as
compared to the density of
water
Estimate by lifting specimen
Density of pure water
1 g/cm³

magnet
![Page 22: IDENTIFYING MINERALS - Weeblymrswelsing.weebly.com/.../identifying_minerals.pdf · IDENTIFYING MINERALS Author: Melissa Created Date: 11/22/2013 12:25:15 PM](https://reader034.vdocuments.site/reader034/viewer/2022043006/5f917e5bd5fed2589061b6be/html5/thumbnails/22.jpg)
Feel
Certain minerals feel
slippery or greasy
Weak bonds allow atoms to
slide past each other
