Karen J. Vanderwolf, David Malloch, Donald F. McAlpine, and Graham J. Forbes


Sulfur Cave (Romania), an extreme environment with microbial mats in a CO2-H2S/O2 gas chemocline dominated by mycobacteria
Serban M. Sarbu, Joost W. Aerts, Jean-François Flot, Rob J.M. Van Spanning, Calin Baciu, Artur Ionescu, Boglárka M. Kis, Reka Incze, Sándor Sikó-Barabási, Zoltan Para, Botond Hegyeli, Nicu-Viorel Atudorei, Casey Barr, Kenneth Nealson, Ferenc L. Forray, Cristian Lascu, Emily J. Fleming, Wilbert Bitter, and Radu Popa

  • Sulfur Cave (Romania) is fed by mofettic emissions of CO2, CH4, H2S, and water vapors
  • A redox gas chemocline (i.e. oxic/anoxic gas/gas interface) occurs in Sulfur Cave
  • Microbial biofilms colonize the cave walls at the gas/gas interface
  • Below the interface, rich deposits of twinned and elongated sulfur crystals are found
  • Sulfur Cave biofilms are important in the search for life in extreme environments


Underground dinosaur tracksite inside a karst of southern France: Early Jurassic tridactyl traces from the Dolomitic Formation of the Malaval Cave (Lozère)
Jean-David Moreau, Vincent Trincal, Daniel André, Louis Baret, Alain Jacquet, and Michel Wienin

  • Hettangian tridactyl dinosaur tracks were discovered in the Malaval Cave (southern France)
  • The tracksite was studied using photogrammetric imaging technique
  • More than 26 footprints of theropods were identified
  • The depositional environment varied from subtidal to intertidal/supratidal flat marsh
  • This work highlights the great interest to heighten palaeoichnological prospections in karsts


Interpreting the origin and evolution of ‘karst’ features from a siliceous hydrothermal terrane: A case study from the Upper Geyser Basin in Yellowstone National Park, USA
Kevin W. Blackwood, Lainee A. Sanders, and Stacy I. Gantt-Blackwood

  • Hydrothermal features in Yellowstone National Park may be products of hypogene speleogenesis
  • The resulting hypogene morphologies may play a vital role geyser function and development
  • Many concepts used to study karst may be applicable in studies of these hydrothermal features
  • Managing these features as a form of karst may improve management of these natural resources


The role of mites in the construction and weathering of siliceous biospeleothems
María José López-Galindo

  • Siliceous speleothems can be developed between granite boulders
  • Siliceous speleothems have a needed biological stage in their development
  • A previously undescribed mite species participate in their construction and weathering
  • Mites are able to excavate niches in the speleothem to complete their life cycles
  • They secrete silk and have a single claw in the form of a hook
