Guano-related phosphate-rich minerals in European caves
Philippe Audra, Jo De Waele, Ilham Bentaleb, Alica Chroňáková, Václav Krištůfek, Ilenia M. D'Angeli, Cristina Carbone, Giuliana Madonia, Marco Vattano, Giovanna Scopelliti, Didier Cailhol, Nathalie Vanara, Marjan Temovski, Jean-Yves Bigot, Jean-Claude Nobécourt, Ermanno Galli, Fernando Rull, and Aurelio Sanz-Arranz

  • 17 guano-related phosphates and 1 sulfate were identified in 22 European cave systems
  • 3 types of phosphates are present: precursors on fresh decaying guano; apatite-group minerals; and Al-, K-, Fe-, Mn-bearing phosphates
  • Spheniscidite and robertsite are the only known occurrence of these minerals in caves worldwide
  • Gypsum is often present, especially in dry environment
  • Radiometric guano dating shows ages up to 7000 years and deposition can be continuous over 1000 years

Fifty years of cave arthropod sampling: techniques and best practices
J. Judson Wynne, Francis G. Howarth, Stefan Sommer, and Brett G. Dickson

  • 110 papers examined (from 1967 - 2018) to explore how cave-dwelling invertebrates were sampled
  • A summary of techniques most commonly applied and appropriateness of these techniques is provided
  • Nearly one-half of the studies applied systematic techniques
  • Few papers provided enough information to repeat the study
  • Inconsistencies in sampling techniques nomenclature observed

Cave dripwater isotopic signals related to the altitudinal gradient of Mount-Lebanon: implication for speleothem studies
Carole Nehme, Sophie Verheyden, Fadi H. Nader, Jocelyne Adjizian-Gerard, Dominique Genty, Kevin De Bont, Benedicte Minster, Ghada Salem, David Verstraten, and Philippe Clayes

  • Cave dripwater isotopic values in agreement with the rainwater trendline of Lebanon
  • The altitudinal trend in the rainwater is demonstrated in cave dripwater
  • Cave dripwater trendline more significant when the infiltration basin is considered

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

ISOLUTION 1.0: an ISOtope evoLUTION model describing the stable oxygen (δ18O) and carbon (δ13C) isotope values of speleothems
Michael Deininger and Denis Scholz

  • A speleothem proxy system model for stable oxygen and carbon isotopes
  • Modeling of disequilibrium isotope fractionation processes in speleothems
  • Modeling of stable oxygen and carbon isotopes in dependence on cave parameters

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
