Flashcards do conjunto (16)
- 1MineralsAre signs in rocks that help understand history. They are naturally occurring, inorganic, crystalline solids with a definite but sometimes variable chemical composition. The structure determines the behaviour of the mineral
- 2RocksThe bulk of solid materials found on earth, a solid mass of small particles of minerals
- 3Naturally OccuringNot synthetically made
- 4Identifying MineralsUse tests like lustre, colour, streak, habit, cleavage, hardness and composition
- 5FractureMeans an irregular breakage or a breakage not along the a plane of weakness
- 6CleavageA breakage along a plane of weakness
- 7HardnessResistance to scratching, scraping, or wearing away
- 8LustreThe character of reflected light of a substance
- 9Crystal FormThe geometric shape formed by the growth of crystal faces
- 10HCl TestThe reaction between weak HCl and calcium carbonate
- 11StreakColour of the mineral when the crystal is powdered
- 12CompoundMaterial made of two or more chemical elements bonded together
- 13Igneous MineralsA mineral created by crystallization from cooling magma
- 14Mineral FormationResults from crystallization, precipitation, combining and recrystallization, or produced from living organisms
- 15Seven Common Rock Forming MineralsOlivine, Calcite, Feldspar (plagioclase and orthoclase), Amphibole, Biotite, Quartz, Pyroxene
- 16Mineral FamiliesSilicates, Sulfides, Carbonates, Halides, Sulfates, Oxides, Native Elements
