| Sumario: | This data publication documents a digitised subset of the historical La Alquimia Compañía Anónima rock collection, originally assembled to identify and evaluate bauxite and related aluminium‑rich ores across the Iberian Peninsula. The dataset comprises 124 hand specimens of karstic bauxites, near‑lateritic bauxites and kaolin‑bearing rocks, each accompanied by detailed macroscopic descriptions, curated metadata and, where available, legacy geochemical labels. For many specimens, major‑element compositions and mineralogical information have been compiled from sample labels and associated analytical archives, complementing recent non‑destructive portable X‑ray fluorescence (XRF) analyses that established the collection as a geochemical reference for Iberian bauxite and kaolin deposits. The data package includes a comma‑separated values (CSV) file with structured specimen metadata, a data description file and a folder of specimen images linked to records through a persistent internal identifier. Together, these resources provide a reproducible, FAIR‑oriented framework for reusing the La Alquimia collection in studies of karst bauxite genesis, lateritic weathering, industrial mineral resources and regional stratigraphy. |
