Sažetak
The aim of this study is to estimate a possibility of using trace elements as paleoclimate proxies in speleothems from some of the deepest caves of Dinaric karst located on Mt. Velebit (depth up to 1421 m). It is well known that there is an relationship between trace element content in speleothems and environmental conditions that can vary due to differences in climatic conditions on a surface, vegetation, chemical composition of bedrock, groundwater movement etc. Methods used in analysis are semiquantitative mineralogical analysis using X-ray powder diffraction to determine mineralogical composition, inductively coupled plasma mass spectrometry ICP-MS and atomic absorption spectrometry (AAS) to determine geochemical composition. Differences in geochemical and mineralogical content show us possibility of using trace elements and mineralogical composition in analysis of palaeoenvironmental changes in Dinaric karst.
