Go to their website and fill out the form, and they will get one in the mail to you as soon as they are able. As part of their outreach, the NCSU Mineral Research Lab located in Asheville will send you a free rocks kit if you are a NC teacher. Check out this link to find a Rocks and Minerals club near you Predetermined questions will be used to break ties. Teams can also bring a field guide and the rocks and minerals list! Scoring: Know binaries Useful books Understanding Phase Diagrams V.B. The materials must be 3-hole punched and inserted into the rings (sheet protectors are allowed). Teams may also bring one magnifying glass and one 3-ring binder (any size) containing information in any form from any source. Teams may be asked multiple questions at each station. 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 viewing any combination of samples, pictures, or recorded/written descriptions. It can also be done as an individual test taking event, where each station has been copied into a test for the team. This event is usually done as stations that teams rotate through. In fact, the ternary diagram is described by % anorthite (%An). It is something students will prep for especially with “feldspar ternary diagrams” as a topic in a different section. It is one of the most common rock bearing minerals in the entire world. Under Plagioclase Feldspars there should be Anorthite. 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. Phase relationships between nepheline, alkali feldspar and leucite are represented at 1 bar, solid line, and at 1 Kb, dashed line, water-vapor pressure x, ternary minimum (cf. 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.
