Sediment dating When sediments cover an archaeological site they are exposed to light and the mineral grains are bleached.Such events can be dated by luminescence methods and the age employed to deter

Tooth enamel and quartz grains Archaeological sites often contain teeth from animals or humans or the site is contained in quartz bearing sediment. The enamel can be dated with Electron Spin Resonance

Unheated rock surfaces The last light exposure of rock surfaces can be dated for establishing the age of e.g. the construction and destruction of walls Granite or other quartz/feldspar containing rock

Ceramics, pottery, bricks and statues Optically Stimulated Luminescence (OSL) as well as Thermoluminescence (TL) can be applied to heated objects made from clay. While the typology of ceramics is a ba

Flint and other heated rocks When rocks have been heated in antiquity the time of the last exposure to high temperatures can be determined Rocks containing amorphous/microcrystalline SiO 2 can be date

Pulsing Pulsing the stimulation allows the separation of quartz and feldspar luminescence signals for dating of mixed mineral samples Sometimes mineral separation in sediment or solid samples is not p

Electron Spin Resonance Sedimentation ages can be established for quartz During long transport in fluvial systems the ESR (EPR) signal in quartz grains is sufficiently reduced to allow the determinati

Radiofluorescence A technique for dosimetric dating of potassium feldspar to establish sedimentation ages. Infrared-Radiofluorescence (IR-RF) is a technique for dosimetric dating of potassium feldspar

Spatially resolved luminescence Single grain dating for mixed sediments or heterogenous radiation fields Not every grain in a sediment sample reflects the same last bleaching and burial history. By an
