Atlantin
Atlantin is a fictional mineral and energy material used in speculative fiction and worldbuilding to evoke oceanic and ancient-technology themes. In most depictions, Atlantin appears as a blue-green crystalline substance with metallic luster, often associated with hydrothermal environments or imagined underwater cities. Its exact chemical composition varies by author, but common portrayals describe Atlantin as a complex metal silicate or sulfide containing trace amounts of titanium, cobalt, and rare earth elements. Reported crystal systems include cubic and tetragonal, with a Mohs hardness around 5.5 to 6.5 and a density near 3.8–4.2 g/cm3. Optical properties are typically in the mid‑1.6 to 1.7 range.
Occurrence and formation: Atlantin is usually linked to deep-sea hydrothermal processes or to fictional geologic settings
Uses and symbolism: In fiction, Atlantin is portrayed as a versatile material for energy storage, catalysis,
