Collecting tips
- Look for Spring Deposits. Travertine forms around mineral springs, especially hot springs. Look for terraced formations, mounds, or layered deposits near active or ancient spring vents.
- Examine Cave Environments. While often called 'cave onyx,' speleothems (stalactites, stalagmites, flowstones) are a form of travertine. Explore limestone caves for these formations.
- Check for Porosity and Banding. Travertine is typically porous and often exhibits distinct layers or bands. This helps distinguish it from other limestones.
- Acid Test. As it's primarily calcium carbonate, travertine will effervesce vigorously when a drop of dilute hydrochloric acid is applied. Always use caution with acids.
