Fissure Ridges: A Reappraisal of Faulting and Travertine Deposition (Travitonics)

Geosciences, 2021
The mechanical discontinuities in the upper crust (i.e., faults and related fractures) lead to the uprising of geothermal fluids to the Earth’s surface. If fluids are enriched in Ca2+ and HCO3-, masses of CaCO3 (i.e., travertine deposits) can form mainly

Ostracode-based aminostratigraphy and aminochronology of a tufa system in central Spain [PDF]

, 2005
In the Priego area, central Spain, extensive tufa deposits are located in three small tributaries located at the head of the 1000 kmlong Tagus River. The deposits are originated after karst-origin running waters emerged from the confines of the canyons ...

Dynamics of precipitation pattern formation at geothermal hot springs

, 2006
We formulate and model the dynamics of spatial patterns arising during the precipitation of calcium carbonate from a supersaturated shallow water flow. The model describes the formation of travertine deposits at geothermal hot springs and rimstone dams ...
