DescriptionTravertine-mound Bridgeport CA.jpg
Hot Springs at Bridgeport, California, Sierra Nevada
English: Calcium carbonate chemically precipitated out as Travertine from the waters of Hot Springs of Bridgeport California.
Precipitation occurs, when environmental conditions of the water change (temperature, pressure, etc. Ex.: emerging from underground) and cause the water to release (part of) its Carbon dioxide as gas. Waterquantity and sediments in this case were large. Biotic material may increase the precipitation by photosynthesis (in this case negligible).
Deutsch: Kalksinter, in großen Mengen hinter heißen Quellen chemisch ausgefällt. An der Ausfällung haben in diesem Fall Algen und ähnliche Pflanzen mit ihrer Photosynthese nur geringfügig mitgewirkt. Die Kalk-Ablagerungen sind - wie in Karsthöhlen - dicht und ohne grobe Verunreinigungen. Das ausgehärtete Sediment von reichlich Quellwasser bildete gering-porösen, harten Travertin.
