| Abstract: | More than 70 samples of Turonian-Danian samples from the eastern and southeastern Russian Plate were studied by the X-ray phase analysis and classical wet chemistry. It has been established that zeolites occur in all studied types of carbonate, siliceous, and clayey rocks. Steadily high zeolite concentrations were revealed in sections of the Santonian formation. Character of zeolite formation was examined simultaneously in both spatiotemporal and lithogenetic aspects. Analysis of the stagewise distribution of zeolites supports the concept of primary volcanogenic nature of the zeolite-forming material and actually represents an indicator of the activity of explosive volcanism in the Late Cretaceous-Paleocene. It is emphasized that high zeolite concentrations in Upper Cretaceous-Paleocene formations are a prospecting guide for zeolite raw material. They can serve as scientific basis for the formulation of prognostic-revision and prospecting works in the study region |
