Indiana Caverns the calcium carbonate precipitates out of the water. The calcium carbonate, in the form of the mineral calcite, a solid, crystallizes onto the bottoms and sides of existing stalactites, stalagmites, helictites, and sheets of flowstone to grow the formations over time. Other minerals are brought into the cave by flowing of water to create white, red, tan, and gray colors on the formations and walls. St. Louis Limestone is primarily made of calcite, but is also known to contain magnesium sulfate, manganese dioxide, ferric oxide, gypsum, dolomite, and aragonite. On the show tour, deposits of calcite, manganese dioxide, and ferric
Calcium acetate/magnesium carbonate therapy is to reach a normal serum phosphorus level, i.e. between 0.81 - 1.45 mmol/l (2.5 - 4.5 mg/dl). Side effects from pharmaceutical therapy such as gastrointestinal disorders, e.g. nausea, constipation or diarrhoea may occur, as well as metabolism and nutritional disorders, e.g. hypercalcaemia or hypermagnesaemia. Calcium acetate/magnesium carbonate Calcium acetate/magnesium carbonate is a fixed-dose combination drug that contains 110 mg calcium and 60 mg magnesium ions and is indicated as a phosphate binder for dialysis patients suffering from hyperphosphataemia (abnormal high serum phosphorus levels). It is registered by Fresenius Medical Care under the trade names Renepho (Belgium) and OsvaRen
