PART III Written Lab: see instructions below (complete on separate sheet)
Metallic mineral ores are important economically and in many industries. If geologists understand
how, when and in what geologic setting these ore rocks (the rocks containing the mineral) are
typically found, it may help in the search for new mineral resources.
A.
Choose one metallic mineral from the following list. On a separate sheet, answer all the
questions below about this mineral. Answers must be written in paragraph form.
B.
Choose another non-metallic mineral and answer ONLY questions 3-7. Answers must be
written in paragraph form.
magnetite
pyrite
copper gold
graphite galena
1.
Where in the United States has this mineral been found in enough abundance to mine
(past of present)?
2.
Choose one mining location. What is the geologic time period during which this
mineral
ore (host rock) was originally formed?
3.
With what type of rock(s) is this metallic mineral associated? (igneous, sedimentary,
metamorphic, or specific name of rocks)?
3.
What are the properties of this mineral?
color
luster
hardness
streak
specific gravity
4.
What is the chemical formula of this mineral?
5.
Is this mineral considered to be a native element? Explain.
6.
What are some important uses of this mineral?
7.
Draw a small sketch of each mineral in its crystal form or natural rock
setting.
You may also include a photo of the mining operation (optional)
and include the source of the photo.
8.
If you were a mineral geologist, where would you suggest searching for the minerals
you described? Explain.
9.
List your sources of information at the end of your assignment.
Book: Author, Title, Publisher, Date of publication, Pages referenced.
Web: url address such as www.mineral.com
Hint: First look up the mineral of interest on the web or in a mineral guide.
Do an internet search for mining of that mineral in the U.S.. When you find a location you
can write about, do a search for that specific mine name or location. Please be sure to list
ALL sources to which you referred. No sources, no credit!!
DO NOT COPY ANY SENTENCES FROM BOOKS OR WEBSITES.
If you must use the author’s exact words, be sure to use QUOTES and give credit by putting
the author’s name and the year of publication in parenthesis after the quotation marks:
“Copper is usually found in nature in association with sulfur.” (minerals.USGS.gov 2009)
