Romania is definitely a fascinating place to visit. One place you should not miss is the small village of Ulmet – Bozioru, in Buzau County, where you will find the Trovant Rocks of Romania – they are believed to have life in them.
They do not only grow but also multiply by themselves, with a deposition rate of about 4-5 cm in 1000 years.
In most cases the stones are round or have a streamed line shape, with no sharp corners.
After rain begins, something incredible happens: like mushrooms they grow and increase in size. each Trovant varies in size from a few centimeters to even 10 meters. Some of them even move on their own.
Their internal structure is also unusual – if you cut them in half you will find age rings like the ones trees have.
Trovants appeared after an earthquake which thought to have happened 6 million years ago. The hypothesis on the seismic origin of the trovants is very well sustained by many laboratory experiments of which the most relevant are those, in which sand spheres are obtained out of wet sand on fine sieves under mechanical shocks.
The term “Trovant” is used in Romanian geology (“cemented sand”) and they aren’t a part of science fiction, they are just an amazing geological phenomena.
Scientists believe that the stones increase in size due to high content of various mineral salts, which are under their shell.When the surface becomes wet, these chemicals start spreading and put pressure on the sand, making the stone “grow”.
But this is just a theory; no well-documented research or conclusive experiments have ever been conducted on these miraculous rocks. For now, they remain a popular tourist attraction in Romania. “Muzeul Trovantilator” (Trovants Museum National Reserve) was inaugurated in 2004 and is now protected by UNESCO.
Trovants were formed in the process that involved: gravitation force, seismic shocks, solution cohesion forces (particularly surface tension) and the adhesion strength between the sand grains and the liquid.
In Romania there are particularly numerous the lower Sarmatian trovants which are very diversely shaped.
Trovants have combined characteristics of plants and rocks, which makes it confusing to categorize them as a non-living or a living creature.
Weather it is alive or not, these spectacular growing stones are something that you need to see and touch if you ever come visiting Romania.
