Assessing provenance of Upper Cretaceous siliciclastics using spectral gamma-ray record

Popis výsledku v původním jazyce

The relationship between contents of clay minerals/grain size and spectral gamma-ray record (concentrations of K, U and Th) in sediments is used for interpretation of sedimentary facies in wire-line logs. However, this approach is often complicated by the multi-component nature of mineralogically immature siliciclastics. As mineralogy of the source material and grain-size sorting during transport both contribute to the detrital composition of the final sediment, a joint study of facies and outcrop gamma-ray spectra can potentially make the latter an effective tool in provenance studies. This paper provides comparison of outcrop gamma-ray data and detailed facies mapping with mineral and chemical composition of the rocks (modal composition; transparentheavy mineral assemblages; WDX SEM chemistry of minerals) and interprets them in terms of provenance changes. We studied the Upper Cretaceous, synorogenic siliciclastic sediments of the Mazak and Godula Formations (Silesian Unit of the We
