Improved field sample selection methods for dating Quaternary sediments based om infrared stimulated luminescence from feldspars

Objective



Luminescence dating methods are able to provide ages for a
variety of sedimentary deposits as they determine the time since the mineral grains were last exposed to light. Thermoluminescence (TL) and optically stimulated luminescence (OSL) measurements can be applied to quartz and feldspar grains in the laboratory but a way of analysing samples in the field would be invaluable in determining sampling strategy. This proposal aims to
develop such field equipment based on the infrared stimulated liminescence (IRSL) from feldspars. Fundamental laboratory
studies would be carried out on mineral separates from a variety of sediments whose age is known and the measurement procedure would be tested on sediment cores brought back to the laboratory. This project could lead to the development of a down hole probe for stratigraphical age assessment, with applications in oceanography, engineering and construction.
