The International Journal of Speleology, the official journal of the Union Internationale de Spéléologie since 1978, has been published since 1964. It is a double-blind, peer-reviewed, international scientific journal that publishes research and review articles concerning all sciences involved in karst and caves, such as geology, geomorphology, hydrology, archaeology, palaeontology, (palaeo)climatology, biology, meteorology, microbiology, environmental sciences, physics, chemistry, mineralogy etc. IJS is published semiannually.

Articles are open access at http://scholarcommons.usf.edu/ijs. The journal is abstracted and indexed in the following services: Directory of Open Access Journals, ISI Thomson Services (Science Citation Index-Expanded including the Web of Science, ISI Alerting Service, Current Contents/Physical, Chemical and Earth Sciences), Bibliography & Index of Geology (GeoRef, Cambridge Scientific Abstracts, EarthScienceWISE (Oxmill Publishing), EBSCO publishing, Geobase, Speleological Abstracts (UIS), Ulrich’s Periodical Directory ™, BIOSIS Zoological record, SCOPUS (Elsevier), and SCImago Journal and Country Rank.

U-Pb dating of speleogenetic dolomite: A new sulfuric acid speleogenesis chronometer
Victor J. Polyak, Paula P. Provencio, and Yemane Asmerom

  • Sulfuric acid speleogenesis (SAS) produces sulfate, carbonate, and oxide byproducts.
  • Many SAS caves no long contain sulfate byproducts that are dateable by 40Ar/39Ar.
  • We applied U-Pb analyses of a dolomite crust sample from Carlsbad Cavern.
  • A model age of 4.1 +/- 1.3 Ma for the dolomite crusts matches the alunite age.
  • U-Pb dating of speleogenetic dolomite is a new way of measuring the timing of SAS.


Morphological and mineralogical characterization of speleothems from the Chimalacatepec lava tube system, Central Mexico
Rafael López-Martínez, Ricardo Barragán, Hugo Beraldi-Campesi, Tomáš Lánczos, Juan R. Vidal-Romaní, Roman Aubrecht, Juan P. Bernal Uruchurtu, Teresa Pi Puig, and Ramón Espinasa-Pereña

  • Opal-A speleothems from acharacterized.
  • Microscopic observations reveal the presence of biomorphs.
  • The formations from Chimalacatepec lava tube system are classified as biospeleothems.
  • The study shed light on the diversity of speleothems from volcanic caves.


Age re-assessment of the cave bear assemblage from Urşilor Cave, north-western Romania
Marius V. Robu

  • Results of the P4, K and Index of Plumpness indicate an earlier evolutionary stage.
  • All three indices should be used with precaution when analyzing MIS 3 cave bear sites.
  • Urşilor cave bear population seem to belong to a eastern clade of U. Ingressus group.


Search for an artificially buried karst cave entrance using ground penetrating radar: a successful case of locating the S-19 Cave in the Mt. Kanin massif (NW Slovenia)
Andrej Gosar and Teja Čeru

  • Cave entrance buried under debris should be located using a geophysical method.
  • For thick debris which overlays limestone surface a low-frequency GPR was selected.
  • GPR profiles were measured across rough surface using special RTA antennas.
  • In recorded radargrams a topographic depression with the cave was clearly imaged.
  • The exact cave location and debris thickness were proven by successful excavation.


Life in the Underworld: Anchialine cave biology in the era of speleogenomics
Jorge L. Pérez-Moreno, Thomas M. Iliffe, and Heather D. Bracken-Grissom

  • Anchialine cave organisms serve as ideal study subjects for evolutionary biology.
  • Genomic methods can be especially useful for large-scale biodiversity studies.
  • Genomics has great potential to study connectivity, diversification, & speciation of cave fauna.
  • Transcriptomic approaches will elucidate the mechanisms of evolution in extreme environments.
  • Modern technologies considerably expand the breadth & depth of questions to be answered.


Characterization of minothems at Libiola (NW Italy): morphological, mineralogical, and geochemical study
Cristina Carbone, Enrico Dinelli, and Jo De Waele

  • Fe-rich concretions in Libiola Mine are studied
  • The word minothems is coined for secondary mineral precipitated in mine environments
  • Mineralogy, texture, and chemistry of minothems were analyzed
  • Studied minothems are made of ferrihydrite that transforms into goethite upon aging
  • Low crystalline goethite easily retains toxic elements into its structure
