Dynamics of precipitation pattern formation at geothermal hot springs.

چکیده
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.

Steady states and linear stability analysis of precipitation pattern formation at geothermal hot springs.
A dynamical theory of geophysical precipitation pattern formation is presented and applied to irreversible calcium carbonate (travertine) deposition. Specific systems studied here are the terraces and domes observed at geothermal hot springs, such as those at Yellowstone National Park, and speleothems, particularly stalactites and stalagmites. The theory couples the precipitation front dynamics...
متن کاملGeochemical Techniques in Geothermal Development: an Update
The ultimate goal of geochemical studies of geothermal systems is to understand the physical-chemical processes responsible for their origin and evolution. The chemical composition of fluids (separated vapor and water), collected from fumaroles, hot springs and drilled wells at the Earth’s surface (25oC) is determined in the laboratory. Using the chemical geothermometers, conservation of mass, ...
متن کاملGeologic Model of the Geothermal Anomaly at Pilgrim Hot Springs, Seward Peninsula, Alaska
Pilgrim Hot Springs has a known shallow geothermal reservoir with temperatures approaching 91 ̊C in the top 100 meters of the system that underlies the main hot springs area of 1.5 km. The deeper reservoir is less understood with similar temperatures at the basement surface 320 meters directly beneath the hot springs. The aspect of this research is to create a stratigraphic model and delineate p...

متن کاملExperimental simulation of evaporation-driven silica sinter formation and microbial silicification in hot spring systems.
Evaporation of silica-rich geothermal waters is one of the main abiotic drivers of the formation of silica sinters around hot springs. An important role in sinter structural development is also played by the indigenous microbial communities, which are fossilized and eventually encased in the silica matrix. The combination of these two factors results in a wide variety of sinter structures and f...
