QUARZ MOORALLA RAUCHQUARZ (Miniatur), Mooralla Victoria Australien
Quarz ist ein robustes kristallines Mineral, das aus Siliziumdioxid besteht. Seine Struktur besteht aus einer kontinuierlichen Anordnung von SiO4-Silizium-Sauerstoff-Tetraedern, wobei jedes Sauerstoffatom zwischen zwei Tetraedern geteilt wird, was zu der chemischen Formel SiO2 führt. Diese Klassifizierung ordnet Quarz strukturell als Gerüstsilikatmineral und von der Zusammensetzung her als Oxidmineral ein. Es ist nach Feldspat das zweithäufigste Mineral in der kontinentalen Erdkruste.
