Potassium levels in seawater are 392ppm and are an important component of Aragonite.
These two elements also help with the formation of Aragonite in the coral skeleton.
The calcium carbonate(CaCO3) in coral reefs and in the shells of other marine calcifiers comes in two different mineral forms:
calcite and Aragonite.
This is because seagrasses take up CO2 in
the water column through photosynthesis and elevate the Aragonite saturation state,
potentially offsetting ocean acidification impacts at local scales.
Due to ocean acidification, it is projected that
by 2050 only about 15% of coral reefs will be in areas where Aragonite levels are adequate for coral growth.
They are composed of an organic substance(a scleroprotein named conchiolin)
and of calcium carbonate(usually in the form of Aragonite)arranged in concentric layers, the outermost of which are mostly nacreous.
The tour will help you to learn about the process of petrifying objects, how the thermal water is discharged,
about the pipeline that is a few decades old and is plugged by Aragonite and how sinter and Aragonite is collected.
