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
