Education

Graduated in geology in 1987; Master degree in geology in 1990; Doctorate of geological sciences in 2002; all degrees at the Geology Department of Faculty of Natural Sciences and Engineering of the Ljubljana University. Her doctoral thesis with the title »The relationship between the autochthonous chemical and mechanical weathering during formation of karst caves« deals with weathering of limestones (incomplete solution) in caves and production of carbonate clastic sediments.

Research activity

  • Karst & cave sediments: composition, origin, age
  • Mineral composition of cave fluvial sediments and incomplete solution of limestones in the karst caves
  • Paleomagnetic dating of clastic sediments and flowstones: in collaboration with Institute of Geology CAS from Prague
  • Origin of the soils on karst surface / red soils (terra rossa soil):  undissolved remains of limestones and non-carbonate rocks, eolian influence
  • Karst geomorphology: morphology & lithology & tectonic and time
  • Interpretation and promotion of karst phenomena for public (applicable projects, lectures, exhibitions). Example: exhibition for Postojnska Cave – EXPO Postojna Cave Karst; IPA-EU project for regional cooperation Slovenia/Croatia: Life and water on karst - ŽIVO! (Life)

 

Research field

  • The basic field of her research work include karst geology, where she study carbonate lithology and weathering, karst and cave sedimentary environments, mineralogy of karst sediments, speleothem chronology and karst geomorphology. She participates in the Institute program Karst Research: in several national and international projects and projects for external customers (for example planning of new highways and railway). Her research work deals mostly with the mineralogical analyses of clastic cave sediments, analyses of mineral and crystalline structure of calcite in caves and paleomagnetic analysis of cave sediments in collaboration with Czech Scientists (see Cobiss). The results obtained are original and new, and have yielded many new insights about the geomorphic evolution of classical karst. During her research work she studied the geomorphology of the various areas of the Dinaric karst, karst in China, France, Australia, Iran and the United Arab Emirates.
