Direct age determination of objects is a cornerstone of archaeological research, but also offers fields of application in the geosciences, biosciences and environmental sciences, as well as climate and solar research.

14C dating is a universal and precise method for determining the age of organic materials in particular. It covers historical times up to approx. 49,000 years before today.

With two MICADAS AMS systems, CEZA’s 14C laboratory has the most modern and globally recognised equipment in the field of radiocarbon analysis, with which even very small sample quantities in the milligram and microgram range can be dated.

Luminescence dating

The age of fired objects (ceramics, bricks, etc.) or the deposition/covering of sediments can be determined with the help of luminescence dating.

Selected dating methods from the field of geosciences, such as the determination of the isotope systems rhenium-osmium or platinum-osmium, complete the range.


Dendrochronology in the narrower sense is the only scientific method that allows the age of subfossil and historical wood to be determined to the exact year. It has therefore been used extremely successfully for decades in many areas of archaeological, art historical and geoscientific research for the calendar dating of wood.
