Practical Mineral ID Labs
There are several mineral ID labs to complete. Each lab
introduces various methodologies of mineral
identification. Results of these labs when performed
with the client sample can then be used to compile the
Course Project (see Mineral id tab)
ANCILLARY MINERAL LAB: THIN
SECTION
During this lab you are to make a
thin section from a rock specimen of your choice,
granite preferred. The thickness of your section should
be as close as possible to the standard of 30µm. It is
therefore essential that your first section contains the
mineral quartz.
MINERAL ID LAB: SPECIFIC
GRAVITY
During this Lab you will establish the
density of a mineral specimen,
preferrably the client sample, using the Hydrostatic
Pan and Pycnometer methods.
MINERAL ID LAB: HM, Color,
Luster, Streak
During this lab you will use simple
physical tests to establish Mohs Hardness, Color,
Luster and Streak of a mineral sample.
MINERAL ID LAB: Mag, Rad,
Organo, UV
During this lab you will use your
physical senses, your cell phone sensors as well as
ultraviolet light testing to collect additional mineral
identifying properties on a sample.
MINERAL ID LAB: Simple
Chemistry & Flame
During this lab you will execute
simple chemical and physical tests, such as open
and closed tube tests, fusibility, and ion paper
chromatography on a mineral sample.
MINERAL ID LAB: Dry XRF
& XRD Analysis
During this Lab you will use x-
ray fluorescence (non-
destructive) to establish semi-quantitative
chemical mineral composition and x-ray
diffraction techniques (destructive) to interpret a
minerals crystallography and variant identity.
MINERAL ID LAB: Wet
Geochemical Analysis
During this Lab you will
proceed with the digestion of a
mineral to use spectrometric / mass
spectrometric analysis for chemical and trace
elements.
MINERAL ID LAB: Optical
Mineral ID
During this Lab you will use
the Polarized Light Microscope
with grain mounts and thin sections as well as
the Gem refractometer to establish the optical
properties of a mineral sample.

Labs have DEADLINES! Consult class schedule / CANVAS
Labs have NO repeats! First grade counts!
Labs are NOT group work. To be completed individually!
