Abstract

U zadnja dva desetljeća metode za određivanje starosti sedimenta su drastično uznapredovale. Dobivaju se podaci koji su vrlo visokih preciznosti i s lakoćom se uzorci mogu svrstati u geološki slijed događanja. Postoje brojne metode mjerenja i određivanja koje imaju različite vremenske dosege, ovisno o radioaktivnom elementu. Najčešće korištene metode se temelje na radioaktivnom raspadu izotopa, a neke od njih su metoda Uran – Olovo, metoda Kalij – Argon, Rubidij – Stroncij, a za organske uzorke koristi se metoda Ugljika – 14 i mnoge druge. Do danas su sakupljeni podaci o geološkim procesima, klimatskim uvjetima, promjenama u okolišu i evoluciji čovjeka u kvartaru, ali i u drugim geološkim razdobljima.

Abstract (english)

In the last two decades, methods for determining sediment age have improved dramatically. Today, data are very precise and samples can be easily classified into a geological sequence of events. There are a number of measurement and determination methods that have different time ranges, depending on the radioactive element that is used in analysis. The most commonly used methods are based on radioactive isotope decay and some of them are Uranium - Lead method, Potassium - Argon method, Rubidium - Strontium, and for the organic samples Carbon – 14 is used as well as a lot ofothermethods. Today, there are a lot of collected data about geological processes, climatic conditions, changes in the environment and human evolution in the Quaternary, but also in other geological periods.
