The number of scientists and correspondingly the flood of publications explode. “Between 2008 and 2014, the number of scientific articles catalogued in the Science Citation Index of Thomson Reuters’ Web of Science grew by 23%, from 1.029,471 to 1

Kinetic fractionation of 18O and clumped isotopes 13C18O in calcite precipitated to speleothems in cave environments renders the paleo-climatic interpretation of these proxies difficult. Therefore a better understanding of the processes generating th

Outgassing of CO2 from thin water layers of a solution of CaCO3 in an H2O -CO2 system plays a crucial role in the precipitation of calcite. Understanding the process of outgassing of CO2 during precipitation of calcite to the surface of stalagmites i

When calcite is precipitated from a water film on top of a stalagmite to its surface, the carbonate in the solution and consequently also the carbonate in the calcite deposited becomes enriched in the heavy isotopes 18O and 13C (Hansen et al. 2016; D

O speleogenetskem pomenu vode, ki iz toplega vlažnega zraka kondenzira na hladne jamske stene je napisanega veliko. Kondenzirana voda se hitro uravnoteži z ogljikovem dioksidom v jamski atmosferi, zato raztaplja apnenec in pri tem tvori različne s

When water from the surface, e.g. from a lake, fl ows down through porous carbonate rocks, through a region with high hydraulic conductivity and encounters the water table of a phreatic aquifer, both waters mix by diffusion along their boundary. In a

We report on sinter terrace forms on the centimetre scale observed on the top and at the base of a stalagmite in Škocjanske jame (Škocjan caves). These exhibit connected rimstone dams, forming a net-like pattern with active water pools inside. The
