BOHINJ GEOLOGY

Bohinj can be explored in various ways – including geologically.

Interesting historical facts and stories will deepen your understanding of the development of Bohinj through time and space.

TYPES OF ROCK IN BOHINJ

The oldest rocks are parts of the 250 million years old Werfen layers. The largest surface area is covered by carbonate rocks, which consist of limestone, limestone with chert, and dolomite.

There are many raw mineral sites in Bohinj. Some, especially iron ore (Bobovec), were also the original reason for settling in Bohinj.

Geologically youngest are the effects of the glacier in Bohinj (the characteristic “u-shape”, which is especially visible in the Upper Bohinj Valley), limestone sediments (glacial moraine), and steep gorges.

Through the centuries, water-carved beautiful riverbeds that sometimes reach a depth of up to 20 metres and get as narrow as only 1 metre (riverbeds of Mostnica, Ribnica, Jereka, and Grmečica).

TECTONIC STRUCTURE

Bohinj lies in the heart of a tectonically very active area. Due to tectonic shifts, which have, and still do create the Alps, a process, which was fastest 25 million years ago, Bohinj regularly experiences earthquakes.

MINERAL RESOURCES

Bohinj is an area with smaller mineral resource sites. In the mountains (Especially on Rudno Polje and Pokljuka), iron ore (a. k. a. Bobovec) with its characteristic brown colour and rounded shape can be found.

There are also smaller quantities of bauxite, manganese ore, lake chalk at the lake, and a few layers of brown coal.
