[edit]DescriptionFleinsbrunnenbach Moos+Kalk Erms-Tributar Schwaebische-Alb.jpg |
Deutsch: Detail vom Kalktuff am 7-m-Wasserfall (Talverengung und Gefällstufe in den Liegenden Bankkalken, ki4) des sehr kleinen Baches „Fleinsbrunnenbach“ bei Seeburg (Bad Urach), Schwäbische Alb. Der kleine Bach, von der Karstquelle bis zur Mündung in die Erms nur 1,5 km lang, führt – gemessen an der Wassermenge – enorme Mengen an gelöstem Calciumcarbonat mit sich, die am Wasserfall von Palustriella commutata (Moos) als Kalktuff chemisch ausgefällt werden. Im hier sichtbaren ersten Stadium ist der Kalktuff eine leicht zähe, wässrig-braune Masse, die trocknend, das weiterwachsende Moos umkrusten. Das Aufkommen an Kalktuff ist vor allem in den wasserreicheren Warmzeiten des Holozäns mächtig angeschwollen. Die Forschung zweier geologisch paläontologischer Universitätsinstitute hat den Bach 1993-1995 näher untersucht und festgestellt, dass hier auch kalkbildende Lebewesen (Cyanobakterien) mikrobiologisch Kalktuff-Wachstum verursachen. English: Detail of calcareous tuff at the 7-m-water-fall of the very tiny rivulet “Fleinsbrunnenbach”, in a valley directly after “Seeburg” (en:Bad Urach), Swabian Alb. The rivulet messures only 1,5 km from karst spring to its flowing into rivulet “Erms”. Fleinsbrunnenbach’s water carries an enormous amount of soluted calcium carbonate, which is chemically precipitated by Palustriella commutata (class of mosses: Bryophyte) as seen in the photograph. When freshly sedimented, the calcareous tuff is a washy-brown mass, when dry, it hardens and incrusts the mossplants, which continue to grow. Research done on the Fleinsbrunnenbach in 1993-1995, published in “Sedimentary Geology 126 (1999) 103–124”, even found „organic substrates, particularly cyanobacteria-dominated microbial mats and biofilm”, that are covered by calcium crystals. |
