Quartz has been the main mineral used for optically stimulated luminescence OSL dating of sediments over the last decade. A new method of dating potassium feldspar grains from aeolian sands is demonstrated. A luminescence signal is measured whilst the grains are stimulated in. Portable Spectrofluorimeter for non-invasive analysis of cultural heritage artworks using LED sources.
Luminescence dating refers to a group of methods of determining how long ago mineral grains were last exposed to sunlight or sufficient heating. In this study, quartz optical stimulated luminescence (OSL) and K-feldspar post- IR infrared (IR) stimulated luminescence (pIR-IRSL) dating methods have been.

This paper aims to provide an overview concerning the optically stimulated luminescence OSL dating method and its applications for geomorphological research in France. We tested the suitability of K-feldspar post-IR IRSL methods using two sites with independent radiocarbon dating – shorelines at Harper Lake and Silver Lake. Beach ridges that form during seaward migration of a shoreline indicate the successive positions of past shorelines; their age and distribution can therefore provide a geological record of past coastal changes Tamura,
