Summary: The network of lava tubes is one of the most unexploited natural wonders of the Galapagos Islands. Here, we provide the first morphological, mineralogical, and biogeochemical assessment of speleothems from volcanic caves of the Galapagos to

Bubble trail and folia in cenote Zapote, Mexico: petrographic evidence for abiotic precipitation driven by CO2 degassing below the water table
Autor: Rafael López-Martínez, Fernando Gázquez, José M. Calaforra, Philippe Audra, Jean Y. Bigot, Teresa Pi Puig, Rocío J. Alcántara-Hernández, Ángel Navarro, Philippe Crochet, Liliana Corona Martínez, Raquel Daza Brunet
Publikováno v: International Journal of Speleology, Vol 49, Iss 3, Pp 173-186 (2020)
Folia are speleothems that resemble bells, inverted cups, or bracket fungi, and whose origins are still controversial. Cenote Zapote (an underwater cave) in the Yucatán Peninsula (México), is home to some of the largest folia reported to date. Thes

Publikováno v: Water, Air, and Soil Pollution. 187:65-80
Use of δ11B provides a solid tool for discriminating hydrogeochemical processes in complex coastal aquifers. Its efficiency increases markedly when it is applied along with other major or minor constituents. Nevertheless, various factors may affect

Speleothems in gypsum caves and their paleoclimatological significance
Autor: Angel Fernandez-Cortes, José M. Calaforra, Paolo Forti
Publikováno v: Environmental Geology. 53:1099-1105
This article highlights the relationship between speleothems growing inside gypsum caves and the particular climate that existed during their development. Speleothems in gypsum caves normally consist of calcium carbonate (calcite) or calcium sulphate

Geological and environmental implications of the evaporite karst in Spain
Autor: Juan José Durán, F. Cardona, Federico Ortí, P. Garay, José M. Calaforra, Francisco Gutiérrez
Publikováno v: Environmental Geology. 53:951-965
In Spain, evaporite outcrops cover approximately 7% of the total area of the country. Most of the evaporitic formations are made up of Ca-sulfates (gypsum/anhydrite) or Ca-sulfates and halite. Certain Paleogene marine evaporites also contain K-Mg-chl
