Abstract

The data set contains data on thin layers of altered tuffs and tuffites in the Upper Jurassic-Lower Cretaceous boundary beds of Western Siberia found in well cores. A list of sections is given for wells in which these interlayers are found, indicating the depth of origin (measured by core and geophysical logging), their description (thickness, structural features, predominant composition), lithostratigraphic linking, information about published research results. According to the litho- and biostratigraphic linking, the tuffaceous interlayers are indexed, those indexes are correlated with subregional pyroclastic levels in accordance with the tephrostratigraphic scale developed for the Upper Jurassic – Lower Cretaceous  boundary beds of Western Siberia.
