What is the difference between tuff and tufa rock?

Tuff and tufa are both geological formations, but the provided sources only discuss volcanic tuffs and do not provide details on tufa rock. Tuffs in regions like the Kapthurin Formation originate from volcanic activity and help researchers date archaeological layers.

What we know

• The Kapthurin Formation features tuffs and extrusive igneous rocks associated with Rift Valley volcanic activity. [2]
• Tuffs within the Kapthurin sequence have allowed for multiple argon-argon dating studies to analyze early human behavior. [2]
• The Aqua Anio Vetus was an ancient Roman aqueduct that used the river Anio as its water intake source. [3]

Still open

• The provided source package mentions volcanic tuffs in geological formations but contains no information defining tufa rock or its differences from tuff.
