Non-Destructive Characterization Of Variously Colored Gypsum And Aragonite/Calcite Speleothems From The Cigalère Cave (Ariège, France), Martin Vlieghe, Johan Wouters, Gérald Fanuel, Jean-François Drion Du Chapois, Anne Gallez, Stéphane Pire-Stevenne, Gaëtan Rochez, Johan Yans
Non-Destructive Characterization Of Variously Colored Gypsum And Aragonite/Calcite Speleothems From The Cigalère Cave (Ariège, France), Martin Vlieghe, Johan Wouters, Gérald Fanuel, Jean-François Drion Du Chapois, Anne Gallez, Stéphane Pire-Stevenne, Gaëtan Rochez, Johan Yans

The Cigalère Cave is a 21 km-long karstic cave located in the Ariège Department, in the French Pyrenees, and underlies directly the Bentaillou Pb-Zn-Fe sulfide ores. The cave hosts abundant gypsum mineralizations, some of them exhibiting various colorations including blue, yellow, purple, orange and black. Due to strict preservation policies, these colored mineralizations have not been studied much. Here we propose a non-destructive characterization of five distinct gypsum or carbonate speleothem structures from the Cigalère, exhibiting different colorations. To comply with the preservation policies, no sample was taken from the cave, and all speleothems were analyzed in situ using portable …
The Taxonomy And Origins Of Folia: A Brief Review, Donald G. Davis, Louise D. Hose, Harvey R. Duchene
The Taxonomy And Origins Of Folia: A Brief Review, Donald G. Davis, Louise D. Hose, Harvey R. Duchene
International Journal of Speleology
All folia demonstrate a few common elements: folia (singular, folium) are planar or sub-planar speleothems, slanting downward and away from cave walls and ceilings, and genetically associated with fluctuating environmental interfaces. They were first identified and named from examples in western USA hypogenic caves but have since been identified elsewhere in the world. Folia shelves are typically composed of calcite and interweave smoothly along sub-horizontal contours. Calcite accretion, both chemical and mechanical from suspended particles, follows water-surface fluctuations to form protrusions in arrays along walls and ceilings where new accretion tends to follow the water-surface downward during descending phases, gradually …
Correlation Of Geochemical Zones In Great Onyx Cave, Mammoth Cave National Park, To Surficial Geological Units, William Strehl
Correlation Of Geochemical Zones In Great Onyx Cave, Mammoth Cave National Park, To Surficial Geological Units, William Strehl
Mahurin Honors College Capstone Experience/Thesis Projects
Cave passages in Great Onyx Cave, developed within the Girkin and Ste. Genevieve Limestones of Mammoth Cave National Park, contain a variety of secondary features on cave walls, including speleothems such as stalactites, stalagmites, and flowstone, evaporite minerals, and dissolution features such as pits and domes. What secondary features are present on the walls of a cave passage depends on the flow and geochemistry of capillary water that has interacted with the cave passage. In the Mammoth Cave aquifer, five distinct geochemical zones have been broadly defined and each typically contains a particular set of secondary features. Geochemical zonation in …
Low Impact Sampling Of Speleothems – Reconciling Scientific Study With Cave Conservation, Claire L.V. Macgregor, John C. Hellstrom, Jon D. Woodhead, Russell N. Drysdale, Rolan S. Eberhard
Low Impact Sampling Of Speleothems – Reconciling Scientific Study With Cave Conservation, Claire L.V. Macgregor, John C. Hellstrom, Jon D. Woodhead, Russell N. Drysdale, Rolan S. Eberhard
International Journal of Speleology
Speleothems are increasingly valued as important paleoclimate archives and yet the removal of samples from caves can come at a cost to natural heritage, impacting delicate environments with limited mechanisms for repair. Conservation of cave environments is a key responsibility for scientists and, with this in mind, we are working to develop and implement techniques that allow us to extract valuable scientific data, with minimal impact. In this study, we demonstrate the utility of low-impact reconnaissance dating surveys on caves in southern Tasmania and southwest Western Australia as a precursor to the removal of stalagmites for paleoclimate reconstruction. Small flakes …
Co-Authorship Analysis Of The Speleothem Proxy-Climate Community: Working Together To Tackle The Big Problems, Micheline L. Campbell, John N. Callow, Gavan S. Mcgrath, Hamish A. Mcgowan
Co-Authorship Analysis Of The Speleothem Proxy-Climate Community: Working Together To Tackle The Big Problems, Micheline L. Campbell, John N. Callow, Gavan S. Mcgrath, Hamish A. Mcgowan
International Journal of Speleology
Understanding the environmental context of speleothem palaeo-climate proxies is fundamental to their interpretation. We analyse four methodological approaches to accomplish this: stalactite discharge analysis, proxy/process tracer studies, discharge modelling, and geophysics. Datamining produced citation data sets that reflected these methodological sub-disciplines. Social network analysis is used to examine co-authorship within and between these sub-disciplines, and between the joint methodological community and the broader speleothem proxy climate community. Members of the sub-disciplines have become more connected to one another over time, and to members of the other sub-disciplines. High degrees of connectivity between and within communities allows for the rapid and …
Moonmilk As A Human And Veterinary Medicine: Evidence Of Past Artisan Mining In Caves Of The Austrian Alps, Christoph Spötl
Moonmilk As A Human And Veterinary Medicine: Evidence Of Past Artisan Mining In Caves Of The Austrian Alps, Christoph Spötl
International Journal of Speleology
The use of moonmilk for medical and other purposes in the Alps is documented since the 16th century. This article reviews speleological reports and sparse historical accounts about the extraction of moonmilk from 18 caves in the Eastern Alps of Austria in an artisan mining style. One such example from a cave in Tyrol is documented in detail, where moonmilk was mined until the beginning of the 20th century and which, due to its remote location, uniquely preserved traces of both the mining and processing style.
