The Geode of Pulpí, discovered by mineral collectors in 1999, is an ~11 m3 ovoid cavity, the walls of which are covered with metre-sized transparent euhedral gypsum crystals.
The geode is hosted in mineralised Triassic carbonate rocks; the observed mineral sequence goes from iron-carbonates and baryte to celestine and finally gypsum (microcrystalline and as large crystals). Fluid inclusion data show that baryte precipitated above 100 °C, celestine at ~70 °C, and gypsum below 25 °C (Canals et al., 2019).
