Dobšiná mine dump (Hlboká dolka): weathered stibnite

Mine tailings and waste rock
- Type
- Mine tailings and waste rock
Kaufmann et al. (2024, Chemical Geology): in situ δ123Sb of secondary antimony minerals formed by stibnite weathering; some keep the stibnite signature (complete Sb transfer), others (tripuhyite, chapmanite, hydroxyferroroméite, stibiconite) are lighter, precipitated from only part of the dissolved Sb or adsorbed on iron oxides. Hand-sorted ore left on the dump for at least a century; in situ profiles from the grain cores (deposits database, +0.06 to +0.09 ‰) to the rim and then the yellowish Sb oxide crust, increasingly light. Original position of the fragments unknown.
