This repository contains raw and processed data for the paper: "The diagenetic fingerprint of rotliegend sandstones in the groningen gas field" by Mulder et al. (2026). The dataset comprises quantitative point count data of authigenic minerals of Rotliegend sandstones from the Groningen gas field. It also includes processed correlation analysis plot data. This data was used to calculate average authigenic mineral compositions and correlation coefficients.
