Original use
The plant residues are preserved in the typical black bituminous mudstones of Skonca beds. Bituminous layers were formed in the coastal wetland at the end of the Ladinian period. Regardless that the environment was very rich with different plants – even coal was formed – the plant residues were mainly burned out. There are very little determinable residues, therefore the sample with residues of extinct horsetail and conifer is so much more important.
Present use
The described specimen is being preserved, secured and presented as important natural heritage of mining in Idrija with exceptional universal values. It represents one of the natural sites of the Idrija ore deposit. It is a part of the geological collection of Idrija Municipal Museum. Visitors can view it within the permanent museum exhibition “Five Centuries of the Mercury Mine and the Town of Idrija”. It can also be used for different types of mercury heritage promotions.
Original location
