However, today caves are off-limits to rockhounds. Quartz. Mica is so soft (2.5 on Mohs scale) that it can be scratched with a fingernail. Generally white to clear, calcite is easily scratched with a knife. Due to the presence of carbonates (CO3), calcite reacts to most acids (such as hydrochloric acid, HCl) and effervesces on contact. If the substituted atom is not normally tetravalent, it usually contributes extra charge to the anion, which then requires extra cations. Deer, W.A.
