Dataset for Geochemical constraints on the formation of rare-earth vanadates in phosphatic microenvironments: Insights from the second occurrence of anningite-(Ce).

This dataset contains supplementary experimental and geochemical data supporting the findings presented in the associated research article. The study documents the second worldwide occurrence of the rare mineral anningite-(Ce), discovered within a fossilized coprolite from the middle Miocene organodetritic limestones of the Żelebsko quarry (Roztocze region, eastern Poland).
