One room serves as preparation laboratory, where all incoming samples are unpacked and chemically treated to purify the sample and extract the desired minerals in the right grain size.
Investigations on OSL (Optical Stimulated Luminescence) and TL (Thermoluminescence) properties of materials.
Coarse-grained quartz and K-feldspar minerals from supraglacial sheet flow deposits and glacilacustrine sediments within ice-marginal moraines were analysed using the single-aliquot regenerative-dose (SAR) protocol.
Independent age control and clear geomorphological relationships indicate that all samples should yield YD or post-Last Glacial Maximum (LGM) ages.
Linking the timing of glacial episodes and behaviour to climatic shifts that are documented in ice and marine sedimentary archives is key to understanding ocean-land interactions.
In the NW Scottish Highlands a large number of closely spaced (‘hummocky’) moraines formed at retreating glacier margins.
Quartz OSL shine down curves showed low luminescence sensitivity, significant medium-to-slow components, a weak fast component, and scattered SAR data; Linearly Modulated-OSL (LM-OSL) measurements confirmed that the fast component was weak or absent.
