In Slovakia we went to the “Aragonites Caves Ochtina” , this caves have 300 meters of long and the temperature is around 7 Cº.
The aragonite is formed from thermal water or geysers, filtered water that have come into contact with hot rocks located at great depth and have re-emerged to the surface. This water dissolves minerals from rocks in its wake, including calcium. As the thermal waters evaporate, the calcium-containing precipitates and, when in contact with air, combines with oxygen and carbon dioxide to form the crystals of aragonite.
We can found aragonita in the form of stalactites and in the shell of nearly all mollusks and coral skeleton.
This is an example of the aragonite cave :

Hello Silvia and Irene,
How beautiful they are! Could you walk all along the cave? How many people a day can visit this cave? Is there any problem with their preservation?
You are really lucky being able to visit this work of art!!!!
Yes, it's very beautiful, yes, we could walk all the cave, we don't know how many people can visit this cave at day...
the temperature have to be adequate and the moisture, because if not it couldn't continue to form.
Ok, right. I'll keep this cave in my mind in case I can visit it some day.
Thanks
