Abstract
Geological materials (clayey sediments and copper slates) were searched by different nuclear-analytical techniques (instrumental neutron activation analysis, X-ray fluorescence and examination of the natural radioactivity). The bulk analysis of the sediments tested show distinct differences in the concentration of several elements. A ruby laser source has been used with an inductively coupled plasma for the simultaneous determination of trace and minor elements in a compact geological material (copper slate). The distribution of 27 elements in a boring core u-as measured. A special calibration method by multiple laser ablation and signal integration for compact samples is described. Pattern recognition methods has been used for the correspondence of both similar geological zones and elements with similar geochemical behaviour in the material.
