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.

First insight on the genesis of iron oxide-hydroxide biospeleothems in Rancho Chico Lava Tube, Mexico
Rafael López-Martínez, Elizabeth Solleiro-Rebolledo, Rocio Alcántara-Hernández, Teresa Pi Puig, Sergey Sedov, Daisy Valera Fernández, M. Nayeli Luis-Vargas, Yasmany Lima Vera, Jesús Solé, and Ramon Espinasa-Pereña

  • First report of massive Fe oxide biospeleothems in a Mexican lava tube
  • Speleothems are composed of ferrihydrite, halloysite, goethite, and clays
  • Microbial features and 16S data confirm Fe-oxidizer-mediated deposition
  • Soil processes mobilize Fe, enabling microbial precipitation in lava tubes
  • Petrography and geochemistry reveal multiphase, microbially driven genesis
