The International Journal of Speleology is the official journal of the Union Internationale de Spéléologie since 1978 and was founded in 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, archeology, paleontology, (paleo)climatology, cave meteorology, (geo)microbiology, environmental sciences, physics, chemistry, mineralogy, etc. IJS is published three times per year.

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.

Reverse pseudo-gours: a new sub-type of folia observed in the Nerja Cave (SE Spain)
Cristina Liñán Baena, Concepción Jiménez de Cisneros, Yolanda Del Rosal, and Paolo Forti

A new sub-type of folia has been described

Their genesis and evolution occur just at the air-water interface

Feeding water supersaturation degree extremely low

Slow and progressive lowering of the water level

Genesis: precipitation of minerals by rapid degassing of CO2 from water and/or evaporation.


Climate monitoring in the Caumont cave and quarry system (northern France) reveal near oxygen isotopic equilibrium conditions for carbonate deposition
Ingrid Bejarano-Arias, Carole Nehme, Sebastian Breitenbach, Hanno Meyer, Sevasti Modestou, and Damase Mouralis

  • We monitored air temperature, dripwater stable isotopes and modern carbonate, deposited on glass plates at Caumont
  • Dripwater δ18O values reflect thorough mixing in the epikarst and some bias towards the winter season
  • Modern calcite δ13C indicate that prior carbonate precipitation might occur during summer
  • Modern carbonate deposition analysis showed the isotope system is at/very near isotope equilibrium
  • Our results show that Caumont cave is suitable for the study of climate trends in the past


Subaqueous carbonate speleothems as paleotemperature archives – clumped isotope thermometry and stable isotope compositions of inclusion-hosted water
Attila Demeny, Ágnes Berentés, László Rinyu, Ivett Kovács, Gergely Surányi, and Magdolna Virág

  • Subaqueous speleothems yield reliable clumped isotope temperatures
  • Calcite-water oxygen isotope thermometry seems to work for subaqueous speleothems


Rates of diagenesis of tropical insectivorous bat guano accumulations: implications for potential paleoenvironmental reconstruction
Donald A. McFarlane and Joyce Lundberg

  • In tropical, wet guano, maximum acidity, temperature, and k values occur at depths of ~10-30 cm
  • Guano moisture level is the most significant control on k
  • Guano k values can have an enormous range – from 0.01 in wet tropical caves, down to 3 x 10-6 in extremely dry caves
  • SEM studies demonstrate that 3 kyr old guano in extremely dry conditions is essentially unaltered
  • Chitin survival under favorable conditions can thus be extrapolated to timescales of 105 years


Dispersion of artificial tracers in ventilated caves
Claudio Pastore, Eric Weber, Frédéric Doumenc, Pierre-Yves Jeannin, and Marc Lütscher

  • Artificial CO2 was injected in ventilated karst conduits (caves and mines), to assess the airflow
  • Geometrical conduit parameters, air velocity, and tracer dispersion were also carried out
  • The 1-D advection-dispersion model was compared with measured breakthrough curves
  • The theory of dispersion is also compared with dipersion inferred from field data
  • BTC tailing may stem from dead-flow zones that enhance aerosol deposition
