Carbonate Deposition

GEOTHERMAL ENERGY

Carbonate Deposition:

The formation of carbonate minerals due to carbonate precipitating out of solution. Geothermal fluids often contain carbonates and as the temperature of the fluids cool when they reach the surface carbonate minerals precipitate out of the solution.

• Silica Deposition
• Carbonate Deposition
• Alunite
• Other Hydrothermal Deposits

• Hydrothermally Altered Rock

Carbonate deposits come in many forms and sometimes develop into spectacular colorful terraces such as these at Mammoth Hot Springs in Yellowstone National Park, Wyoming. Photo by Darren Atkins

Includes travertine and massive carbonate deposits typically associated with modern chloride-rich alkaline hot spring discharges and/or microbial activity.
