Sinter


Calcareous or calc sinter is a freshwater, which is coming from the top of the rock, calcium carbonate deposit, also known as calc-sinter (synonym travertine). Characteristical for this kind of deposit are a low porosity and a well developed lamination. Calcareous sinter is often mixed up with the term siliceous sinter, which is mostly used in the context of sinter. In order to avoid this misunderstanding it is widely accepted to use the term "sinter" only for siliceous spring deposits and do not use it for calcareous deposits entirely. Deposits are formed from either calcite or aragonite. Precipitation is brought about by degassing of CO2, which decreases the solubility of calcite/aragonite.
