Sažetak
Environmental and climatic changes are potentially recorded in recent terrestrial carbonates, such as speleothems or tufas. Stromatolite-like crusts have been the subject of great interest since they contain mm-size laminae, which are considered to represent annual climatic records. The origin of the light and dark layers has been attributed to seasonal variations in microbial assemblages and their activities, water chemistry and carbonate precipitation rates. In conclusion, both oxygen isotope, as well as geochemical records in the laminar crust to a certain extent reflect the temperature and other environmental conditions during the period of precipitation. However, the exact estimation of the precipitation temperature is not yet possible.
