Abstract
Thermoluminescence: A Tool for the Environmental Analysis of Recent Sediment Cores
Harry H. Roberts, William E. Graves
ABSTRACT
A method has been developed for determining the presence and spatial distribution of minerals in Recent sediment core samples. Autoluminographs are produced of core slabs chilled to 77°K in liquid nitrogen, activated by a strong gamma radiation source (CO60), and then heated rapidly to slightly above ambient temperature. Contrasts between core constituents result from differences in characteristic spectra and variations in light intensity which are recorded on color film. Thermoluminescence of sedimentary materials offers an extension of such valuable techniques as X-ray radiography for assessing diagenetic and environmental characteristics of Recent sediment cores.
