Geocache Description:




Symposium "Sea Magic" 2016:
In 2016 here at the promenade foreign and domestic sculptors worked in an open-air atelier. Their 6 marble works, inspired by the sea, are the works selected at the Symposium "Sea Magic", attended by 12 sculptors from Canada, Ukraine, Macedonia, Greece and Albania.

With chisels, trimmers and compressors, the masters assisted by their assistants are realizing in record time sculptures titled "Golden Sea Cutting", "Dream", "Aphrodite", "Dolphins", "Seagulls" and "Dallga".

We shall take a closer look at the sculpture Dolphins by Niko Godroli.



How marble is formed:
The process of how marble is formed is always pretty similar, no matter what color it is.
Marble is a metamorphic rock, which means that it’s created by the transformation of other rocks such as calcite, dolomite or aragonite.
The process of transformation occurs at high temperatures as well as high pressure underground which restructure the crystals in the rock.

The process started for over 200 million years ago in the Triassic period, with sedimentation, as dead organisms and organic material fell on the earth's surface and formed a thick layer of sediments that were petrified to calcite.
The transformation from calcite, marble was caused by movements of the tectonic plates, when the African plate began to move towards the Eurasian plate.
The pressure and temperature of the Earth initiated the process of change in the sedimentary rocks and made mountains up to 1900 meters height, which are mainly composed of marble. The temperature and pressure required to form marble destroys any fossils and sedimentary texture of the original stone.

The marble at the dolphins is typically white as a result of transformation of almost pure limestone.
The limestone consisted mainly of the mineral calcite as a crystalline form of calcium carbonate CaCO3.
That marble contains much calcium, carbon and oxygen.
The plate's position today

Examples of variations:


The colors of marble due to the minerals which have been transformed indicates:
- White marble is formed of very pure limestone.
- Pink color comes from the presence of manganese.
- Green color is often of serpentine from limestone rich in magnesium or dolomite with silicon impurities. Copper also provides a green color.
- Red marble indicates the presence of hematite.
- Yellow marble due to limonite.
- Black comes from iron oxide.
- Mixture of colors in the marble comes from the pure limestone was contaminated by various minerals.
