Dog tooth calcite, with its distinctive crystal shape resembling canine teeth, has captivated geologists and enthusiasts alike. Its unique structure and remarkable properties have placed it at the forefront of scientific research and architectural applications.
Formation and Structure of Dog Tooth Calcite
Calcite, a common carbonate mineral, crystallizes in various forms. Dog tooth calcite forms when calcium carbonate-rich solutions percolate through limestone or other carbonate rocks. These solutions deposit calcite crystals on existing crystal surfaces, resulting in the characteristic elongated, rhombohedral shape. The “dog tooth” projections form as new crystals grow on the edges of existing crystals, creating a zigzag pattern.
Properties and Comparisons VS Other Calcite Forms
Dog tooth calcite possesses several unique properties compared to other calcite forms:
Physical Properties
- Hardness: 3 on the Mohs scale
- Crystal System: Trigonal
- Density: 2.71 g/cm³
- Cleavage: Perfect rhombohedral cleavage
Optical Properties
- Transparency: Transparent to translucent
- Refractive Index: 1.486-1.658
- Birefringence: Strong
Crystal Morphology
- Shape: Elongated rhombohedra with “dog tooth” projections
