(c) Rachaimer stalactite formation
If a dry cave system is wholly or partially, so it comes to the limestone formation when exiting through ceiling cracks kalkgesättigtes karst water. By release of carbon dioxide to the cave air is exceeded the solubility of calcium carbonate and calcium deposits out.
A similar process is observed in the kettle when hard water is heated, leading to the lime deposits (in this case "scale considered).

out in caves, the slow but steady lime deposits in the formation of stalactites. Ceiling speleothems (stalactites) usually have an inner, more or less fine Kalnal, through which water seeps, and, starting from calcite or aragonite crystals radiating.
stalactites have a large variety of shapes: thin "Macaroni" can be thousands hanging from cave roof, "normal" drip stones are common, but very seldom are Excentriques that grow in part to the crystal orientation of calcite or aragonite, in part, appear totally confused. Cauliflower-like structure (cauliflower Inter) also occur. If
unite the ceiling stalactites with their ground against growing stalactites (stalagmites), formed limestone pillars.
Formation of the speleothems takes a lange, sodass ein Tropfstein viele Jahrtausende alt sein kann. Auch unter Betonbrücken oder in Betonabwasser- oder Kabelkanälen kann man manchmal die Bildung von "Makkaroni" oder Sinter beobachten, wenn man das Alter dieser Bauwerke kennt, kann man die Wachstumsrate dieser "Tropfsteine" abschätzen.
