Spatially resolved luminescence

Single grain dating for mixed sediments or heterogenous radiation fields

Spatially resolved luminescence

Not every grain in a sediment sample reflects the same last bleaching and burial history. By analysing single mineral entities (whether grains or parts of it) different dose populations can be distinguished and models derived for different events of e.g. beaching or deposition.

  • Single grain detection through spatially resolved luminescence

  • Measurement of single grains

  • Detection of bioturbation and mixing

  • Differentiation of sedimentation components, like rock erosion versus aeolian

  • Spatial analysis of heterogeneous samples, e.g. with mineral intergrowth
