“…Indeed, Audra et al (2009) proposed that only calcite forms can be considered as real folia, while Davis (2012) includes a variety of shapes and mineral for the term. Despite most folia reported to date being made of calcite, some examples of folia composed of native sulfur have been described (Hose et al, 2000(Hose et al, , 2009Lugli et al, 2017;D'Angeli et al, 2018).…”

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. These speleothems are currently growing in an active underwater system, meaning this site offers an excellent opportunity to constrain the different formation models proposed for folia, which have traditionally relied on inactive examples. In Cenote Zapote, folia are closely related to bubble trails and cupolas, suggesting an underwater CO2-degassing process. In thin section, they display a succession of columnar-open and columnar-elongated endings in micrite-dendritic fabrics. Our petrographic and geochemical results demonstrate the abiotic origin of these folia and indicate carbonate precipitation from cold water by CO2 degassing below the water table that started at least 5,210 yrs BP. We conclude that these folia formed as a result of subaqueous calcite precipitation around CO2 bubbles trapped below overhanging walls of the cave. The sequential alternation of columnar and micritic fabrics can be explained by changes in the position of the halocline and H2S-rich water mass while the exceptional size is the result of carbonate precipitation from waters saturated in CaCO3 during thousans of years. Then we propose the classification of these speleothems as a subtype of folia. This subtype could be named Hells Bells, respecting its original description.

“…To overprint a flank margin cave in that setting requires that sea-level position and the freshwater lens to be at almost the exact same elevation. Most flank margin caves are found at positions consistent with the +6 m sea-level highstand of MIS 5e [36], but flank margin caves with elevations up to 20 m have been located and are believed to represent earlier highstands, such as MIS 11 [14,37].…”

Diffuse Versus Conduit Flow in Coastal Karst Aquifers: The Consequences of Island Area and Perimeter Relationships

Abstract:The majority of limestone islands are made of eogenetic carbonate rock, with intrinsic high porosity and permeability. The freshwater lenses of small islands are dominated by diffuse flow regimes as the island perimeter is everywhere close to the meteoric catchment of the island interior. This flow regime produces flank margin caves at the lens margin, where dissolution is enhanced by mixing corrosion, superposition of organic decay horizons and higher flow velocities as the lens thins. The lens interior develops touching-vug flow systems that result in enhanced permeability and lens thinning over time. As islands become larger, the area (meteoric catchment) goes up by the square, but the island perimeter (discharge zone) goes up linearly; diffuse flow becomes inefficient; conduit flow develops to produce traditional epigenic cave systems that discharge the freshwater lens by specific turbulent flow routes, which in turn are fed by diffuse flow in the island interior. Locally, diffuse flow to the island perimeter continues in coastal proximal areas between major conduit flow routes to produce flank margin caves. The Bahamian Archipelago represents a case history in which tectonics is limited, the rocks are entirely eogenetic and the diffuse to conduit flow transition is demonstrated.

“…In our dataset, 13% of all ages were excluded from the final age-depth models in the original publications, mostly because they were not in the correct stratigraphic order and were thus considered unreliable. In radiometric dating, out-of-sequence anomalous ages can occur due to diagenetic phenomena affecting the carbonate fabric, and/or sources of error during sample preparation and analysis (e.g., cross-contamination, environmental contamination, spike calibration problems; [65,[140][141][142][143]).…”

The Potential of Speleothems from Western Europe as Recorders of Regional Climate: A Critical Assessment of the SISAL Database

Western Europe is the region with the highest density of published speleothem δ 18 O (δ 18 O spel ) records worldwide. Here, we review these records in light of the recent publication of the Speleothem Isotopes Synthesis and AnaLysis (SISAL) database. We investigate how representative the spatial and temporal distribution of the available records is for climate in Western Europe and review potential sites and strategies for future studies. We show that spatial trends in precipitation δ 18 O are mirrored in the speleothems, providing means to better constrain the factors influencing δ 18 O spel at a specific location. Coherent regional δ 18 O spel trends are found over stadial-interstadial transitions of the last glacial, especially in high altitude Alpine records, where this has been attributed to a strong temperature control of δ 18 O spel . During the Holocene, regional trends are less clearly expressed, due to lower signal-to-noise ratios in δ 18 O spel , but can potentially be extracted with the use of statistical methods. This first assessment highlights the potential of the European region for speleothem palaeoclimate reconstruction, while underpinning the importance of knowing local factors for a correct interpretation of δ 18 O spel . Quaternary 2018, 1, 30 2 of 30and AnaLysis (SISAL) database (SISAL_v1) contains 376 speleothem records from across the globe [3]. About a quarter of these records (92) are from Western Europe, making it the region with the highest density of published speleothem datasets worldwide [3]. This paper reviews these records within the wider (palaeo-)climatic context of Western Europe, with the objective to identify and promote the potential of cave sites in the region for future palaeoclimate studies. Moreover, we test the suitability of a large compilation of speleothem records to reveal the existence of regional trends in space and time [4].While early studies on Western European speleothems principally focused on their availability for temperature reconstruction using δ 18 O of the carbonate [5,6], it was quickly recognised that δ 18 O spel is driven by a complex interplay of regional and site-specific factors, such as moisture source and circulation dynamics, amount of precipitation, dripwater residence time in the overlying karst, cave temperature and ventilation dynamics, and potential kinetic effects during carbonate deposition [7,8]. Due to the filtering effect of the soil-karst system, the δ 18 O spel signal is usually strongly temporally attenuated compared to precipitation δ 18 O, and affected to varying degrees by local noise [4]. This is particularly pronounced at mid-latitude sites and over the Holocene, when ranges in δ 18 O spel are typically small (average standard deviation of Western European δ 18 O spel in SISAL_v1 is 0.36 ) and reflect only moderate climate shifts, as is apparent from other palaeoclimatic evidence (e.g., [9]). Over glacial-interglacial timescales, changes in the seasonality of precipitation and the spatial stationarity of climate patterns need...
