Abstract

Hyperspectral mapping is a very powerful technique for determining the cathodoluminescence (CL) emission characteristics and chemical compositions of materials over relatively large areas and at micron to sub-micron spatial
resolutions (Lee et al. 2005). Using a Cameca SX100 electron probe at Strathclyde University, which is equipped with a silicon CCD spectrograph and energy- and wavelengthdispersive X-ray detectors, we have investigated spatial and
spectral variations in the CL properties of meteoric calcite cements from the Upper Permian of the UK and perthitic alkali feldspars (Na- and K-rich intergrowths) from the Precambrian Klokken syenite, Greenland.
