How does quartz replace fluorite?

Hydrothermal Activity:
Mineral-rich hydrothermal fluids move deep within the Earth’s crust.

Chemical Replacement:
Silicates in the hydrothermal fluids react with fluorite, gradually forming quartz.

Crystal Growth:
Quartz crystals grow on the structure of fluorite, preserving the original fluorite shape.
This process results in quartz crystals that have the form of fluorite.

Dimensions: 5 x 5 x 11.5 in

Locality: Anxi, Quanzhou, Fujian, China
