Thread:Recrystallization (1)

Chert is an example of recystallization. Millions of radiolarian skeletons fall to the sea floor in the abyssal plain and are buried under sediment. Pressure due to burial causes the silica in the skeletons to recrystallize and chert is formed.

Another classic example of recrystallization is aragonite in shells recrystallizing into the more stable form of calcite.
