Rocks & Minerals
Division: Div C – High School
Event Rules: See the National rules manual
National Event Page: Here
Required Materials: Something to write with
There is a formatting error in the event rules in Column 2, Lines 26 & 27 where text was needlessly indented as Willemite and Zircon are not members of the Tourmaline Group.
The Tourmaline Group has a footnote is because Tourmaline is its own mineral AND a group, there are some common minerals in the Tourmaline Group like Schorl and Elbaite.
Under Plagioclase Feldspars there should be Anorthite. It is one of the most common rock bearing minerals in the entire world. It is something students will prep for especially with “feldspar ternary diagrams” as a topic in a different section. In fact, the ternary diagram is described by % anorthite (%An).

This event is usually done as stations that teams rotate through. It can also be done as an individual test taking event, where each station has been copied into a test for the team. Teams may be viewing any combination of samples, pictures, or recorded/written descriptions. They will then be asked to answer questions (multiple choice, fill in the blank, short answer, generating graphs or charts, etc) about the sample, including identification, classification by properties, origin, uses and importance. Teams may be asked multiple questions at each station.
Teams MUST bring a writing instrument. Teams may also bring one magnifying glass and one 3-ring binder (any size) containing information in any form from any source. The materials must be 3-hole punched and inserted into the rings (sheet protectors are allowed). Teams can also bring a field guide and the rocks and minerals list!
High score wins. Predetermined questions will be used to break ties.

The Tar Heel Gem and Mineral Club was formed in 1974 as a nonprofit educational organization for people who enjoy the lapidary arts, earth sciences, and related subjects. The main objectives of the club are to investigate, preserve, and share knowledge of rocks, minerals, and precious stones, and to promote interest in mineralogy, paleontology, earth sciences, and lapidary techniques, among club members and among the general public. The club pursues these goals through publications, meetings, lectures, field trips, exhibits, demonstrations, and other activities.
