Phys. Rev. Lett. 96, 254501 (2006) [4 pages]Dynamics of Precipitation Pattern Formation at Geothermal Hot SpringsReceived 13 January 2006; published 27 June 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 of calcite in caves. We find explicit solutions for travertine domes at low flow rates, identify the linear instabilities which generate dam and pond formation on sloped substrates, and present simulations of statistical landscape evolution. © 2006 The American Physical Society URL:
