Clumped Isotope Temperature Reconstruction Using Stalagmite Drip Cups. [PDF]

open access: yesRapid Commun Mass Spectrom
ABSTRACT Rationale Application of clumped isotope palaeothermometry to speleothems (carbonate cave deposits, e.g., stalagmites and flowstones) has been restricted largely to subaqueous samples because of kinetic fractionation processes that occur during subaerial speleothem formation, which lead to erroneously high inferred temperatures.

Global Warming and Mass Extinctions Associated With Large Igneous Province Volcanism

open access: yesGeophysical Monograph Series, Page 83-102., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Last interglacial sea-level history from speleothems: a global standardized database [PDF]

open access: yesEarth System Science Data, 2021
Speleothems (secondary cave carbonate precipitates) are archives of valuable information for reconstructing past sea levels as they are generally protected from weathering and erosion by their location and can be dated with U-series methods.

Hydrologic Evolution of a Carbonate Aquifer (Dinaric Karst, Croatia)

open access: yesGeologia Croatica, 2010
Dinaric Karst terrains contain specific, lam inatedspeleothems, which line all surfaces of subterraneanvoids including Cretaceous bedrock limestone, and oldervadose speleothems and clastic sediments.

An attempt to identify source areas of clastic deposits from selected caves of the Prokletije Mountains (Montenegro): a mineralogical and U-series geochemistry approach

open access: yesInternational Journal of Speleology, 2023
The Prokletije Mountains/Albanian Alps are the highest part of the Dinaric Mountains. Paradoxically, these mountains and their cave areas remain among the most enigmatic in Europe, having only recently become subjects of scientific research and cave ...

Constraining Holocene hydrological changes in the Carpathian–Balkan region using speleothem δ18O and pollen-based temperature reconstructions [PDF]

open access: yes, 2014
Here we present a speleothem isotope record (POM2) from Ascunsă Cave (Romania) that provides new data on past climate changes in the Carpathian–Balkan region from 8.2 ka until the present.

Speleothems in Cova des Pas de Vallgornera: their distribution and characteristics within an extensive coastal cave from the eogenetic karst of southern Mallorca (Western Mediterranean)

open access: yesInternational Journal of Speleology, 2014
The abundance and variety of speleothems are undoubtedly among the remarkable features of Cova des Pas de Vallgornera, the longest cave system in Mallorca Island developed in the eogenetic karst of its southern coast.
