Sažetak
Speleothems can grow for thousands of years. During that time they encode palaeoclimatic information in their geometry and geochemistry. A great work has been done over the past decade with a variety of techniques that have been used to investigate trace elements included in the structure of speleothems (CaCO3) or isolated within the crystal lattice. Solid state NMR can bring new information for high resolution palaeoclimate and palaeoenvironmental reconstruction. Until now, MAS NMR was used to investigate 31P in speleothems. The aim of our work is to determine the possibility of investigating other trace elements in the structure of speleothems such as 23Na and 27Al using solid state NMR in order to contribute to the understanding of the conditions of their formation. Samples in the study are taken from various locations in Croatian karst that is characterized by complex speleogenesis influenced by different climatic, geological, hydrological and geomorphological environments.
