Abstract

One area of recent speleothem research has been the analysis of luminescence variations. Here we present luminescence data for the dominant luminescence centre (excitation wavelength 330 to 390nm; emission wavelength 390 to 460nm). For many speleothems this peak can be resolved into two luminescence maxima. Data presented here, from a variety of speleothems and a wide range of cave locations, suggest that in many cases the ratio of luminescence intensity of these two luminescence intensity sub-centres can provide a more sensitive record of luminescence variations. Also, in some cases, it can provide a palaeoenvironmental proxy.
