THE LIVING AND GROWING STONES OF ROMANIA

Growing Stones Of Romania

Growing Stones of Romania

Romania is known for this natural stones which quite literally grow by themselves. these stones are known as Trovants.

It is difficult to imagine that stones can really grow, but these stones seem to be alive!

The Romanian Trovants Museum Natural Reserve is located in Valcea County, close to the road connecting Ramnicu Valcea and Targu Jiu, 8 km far from Horezu. Here in a small village named Costesti, there are some fascinating and mysterious stones, called trovants, which are believed to have a life in them.

There are sand or grass levels with trovants in many places of Romania, but the ones in the region of Costesti are particularly impressive because of diversity of their shapes (mostly spherical or ellipsoidal) and dimensions.

The term “Trovant” is a term used in Romanian geology.

Trovants – represent a quite bizarre geological phenomenon, which consist in spherical shapes of cemented sand due to some powerful seismic activity that occurred 6 million years ago.

they have a strong stone core but their shells are made of sand. Scientifically these giant stones are sandstone concretions and the weird forms are achieved by these stones is an irregular secretion of cement.

But Geologists argue that these stones are the result of a cementation process that occurred millions of years ago in this region .

The earthquakes definitely contributed to the creation of the first trovants. It is assumed that trovants consist of a stone core, with an outer shell of sand.

What makes these formations unique and mysterious is that they are reproducing after coming in contact with water.

After heavy raining the stones grow starting with 6-8 millimeters and ending with 6-10 meters.

In year 2006 a museum (Muzeul Trovantilor)was built in Costesti, a village in the Valcea to host some of these remarkable pieces. Within the walls and outside of this museum, visitors can see these stones in different shapes and sizes.

In addition, just like the famous rocks in Death Valley, California, the trovants often move from one place to another place.

Complex aggregates of two ore more trovants can often be found. There is no mineralogical difference between these strange pseudoconcretions and the surrounding sands.

Their cement is often carbonate-type and no distinct nucleus can be found inside them.

Many hypotheses have been produced on their origin. However, 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”.

Trovants

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.

The great trovants found in the thick sand beds reflect great initial amounts of solutions in the bulk of the sandy sediment. The perfect spherical shapes which sometimes can be found suggest great magnitudes and durations of the paleoearthquakes.

A 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.

On Earth trovants of different ages have been recorded in in Russia, Siberian Platform, and Wyoming.

There are also in the Carpathians area (a mountain range in central Europe that extends from Slovakia and southern Poland southeastward through western Ukraine to northeastern Romania).

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.
