The Selenite Sphere from Madagascar is a stunning natural mineral formation composed of selenite, a type of gypsum crystal. This beautiful sphere features delicate, transparent crystals that reflect light and create a mesmerizing visual effect.
Geological Information
Selenite is a mineral composed of hydrated calcium sulfate (CaSO4·2H2O). It forms through the evaporation of ancient seas and salt lakes, often creating large, transparent crystals. The Selenite Sphere from Madagascar is likely to have formed in a similar environment, where mineral-rich water evaporated, leaving behind a deposit of selenite crystals.
Formation Process
The formation of selenite crystals like those found in the Selenite Sphere from Madagascar involves a process known as crystallization. As mineral-rich water evaporates, the concentration of dissolved minerals increases, eventually leading to the formation of crystals. In the case of selenite, the crystals can grow quite large, forming transparent, tabular crystals.
