Cheat Sheet
- Bravais Lattices & Crystal Systems -
Understand the seven crystal systems - cubic, tetragonal, orthorhombic, hexagonal, trigonal, monoclinic, and triclinic - and how they derive from the 14 Bravais lattices (as defined by the International Mineralogical Association). Use the mnemonic "Crazy Tigers Only Hate Tall Monkeys Tremendously" to recall each system in order. Mastery of these categories is key to any crystal system quiz and mineral properties quiz.
- Mohs Hardness Scale -
Familiarize yourself with the ordinal scale from 1 (talc) to 10 (diamond) to gauge scratch resistance - this scale is widely taught in geology courses at institutions like the University of Wisconsin - Madison. Remember the phrase "The Girls Can Flirt And Other Queens May Serve Cake" to memorize common hardness values. Practical scratch tests will boost your confidence in any mineral quiz or crystal quiz scenario.
- Cleavage vs. Fracture -
Differentiate perfect cleavage - in which minerals like mica split along flat planes - from irregular conchoidal fracture seen in quartz or obsidian (as detailed in USGS mineral guides). Practicing on hand samples or high-res images helps cement these distinctions for crystal system quizzes. Recognizing these surface patterns elevates your performance on mineral properties quizzes.
- Crystal Habit & Morphology -
Learn common habits - prismatic (tourmaline), fibrous (asbestos), bladed (tremolite) - and how these forms relate to internal symmetry (see Mindat.org for visuals). Relate habit to crystal systems: hexagonal crystals often exhibit six-sided prismatic shapes. Identifying habit quickly is a secret weapon in any crystal system quiz.
- Specific Gravity & Density -
Calculate specific gravity (SG = ϝ_mineral/ϝ_water) to distinguish dense minerals like galena (SG ~7.5) from lighter ones like quartz (SG ~2.65), as outlined in Cambridge University mineralogy references. A handheld balance and water displacement can confirm SG experimentally. Mastering this calculation rounds out your expertise in mineral properties quizzes and crystal quizzes.
