It is calcium-carbonate dissolved by acidic ground-water, precipitated from the solution when the water emerges from the spring. Tufa is related to stalactites and stalagmites but of coarser, often softer, physical texture.
Tufa is formed when calcium-rich groundwater interacts with carbonate minerals, typically limestone or dolomite, and precipitates out calcite. This process usually occurs in caves, hot springs, or desert springs where the water flows or seeps to the surface, depositing layers of tufa over time.
Marble is formed when limestone is metamorphosed. This process occurs when the mineral calcite in limestone recrystallizes due to heat and pressure, resulting in a denser, harder rock with a crystalline structure.

Calcium and carbon form limestone. limestone caves are formed by water and other materials eroding the cliff to form a cave.
They - or it? - are normal karst caves, formed in limestone by its dissolution by water. I believe they still carry a stream: if so they are still forming.
