HYPOGENE SULFURIC ACID SPELEOGENESIS AND RARE SULFATE MINERALS (FIBROFERRITE, JAROSITE SUBGROUP) BAUME GALINIERE CAVE (ALPES-DE-HAUTE-PROVENCE, FRANCE)
Abstract:

 

The oxidation of sulfide sources (H2S gas, pyrite, hydrocarbons) produces sulfuric acid that strongly reacts with bedrock, causing limestone dissolution and complex interactions with other minerals. This type of cave development, known as sulfuric acid speleogenesis, is a subcategory of hypogenic speleogenesis, where aggressive water rises from depth. It also produces uncommon minerals, mainly sulfates. Baume Galinière is located in Southern France, in the Vaucluse spring watershed. This small maze cave displays characteristic features such as corrosion notches, calcite dikes and iron crusts, and sulfate minerals. Thirteen minerals were identified, including elemental sulfur, calcite, quartz, pyrite, goethite, gypsum, fibroferrite, plus all of the six members of the jarosite subgroup (jarosite, argentojarosite, ammoniojarosite, hydroniumjarosite, natrojarosite, plumbojarosite). The Baume Galinière deposits are the first documented cave occurrence of argentojarosite and the second known occurrence of plumbojarosite, hydronium jarosite, ammoniojarosite, and fibroferrite. Together with other hypogenic caves in the Vaucluse watershed, Baume Galinière Cave owes its origin in buried conditions to deep water rising along major faults, mixing with meteoric water at the contact of the karst aquifer and overlying impervious cover, and causing pyrite deposition. Sulfuric acid speleogenesis occurred later after base level drop, when the cave arrived in shallow phreatic then in vadose zone, with oxidation of pyrites involving sulfidic gases. Attenuated oxidation is still occurring through condensation of incoming air from outside. Baume Galinière Cave records the position of the paleo-cover and documents its retreat in relationship to valley incision caused by uplift and tilting of the Vaucluse block during Neogene.
