The first tufa sampling campaign accomplished / 20.08.2019

On August 19, a group of researchers and students performed the first sampling of water, tufa and bedrock in the Krka valley, Slovenia

With great support of Mr. Emil Glavič from the “Kajak raft klub Žužemberk” and enthusiastic students of geology from the Faculty of natural sciences and engineering at the University of Ljubljana, we took barrage tufa samples at 18 consecutive barriers between Zagradec and Dvor, as well as water samples from Krka river at the barriers and its main tributaries in this flow section. The bedrock was sampled, too. The water and rock samples will be analysed for elemental, mineral and isotopic composition of carbon, oxygen, magnesium, strontium and uranium, to estimate the fraction of authigenic carbonate in the fluvial carbonate formations.
