Physio-Géo, 2012 Description and speleogenesis of some caves in the calcareous formations of the "Massif des Calanques" in relation with lithology and tectonic environments: faults, Sormiou anticline, submersion coast in the "Calanques" valleys, karstic landscapes until ...

Paleoceanography and Paleoclimatology, Volume 41, Issue 4, April 2026.Abstract The Penultimate Deglaciation (PDG) saw warming from the Penultimate Glacial Maximum to the Last Interglacial (LIG). We present 18‐kyr transient simulations through the PDG into the LIG using a fully‐coupled three‐dimensional ocean‐atmosphere model forced with Paleoclimate Modeling Intercomparison Project Phase 4 transient boundary conditions ...

Sedimentology, Volume 73, Issue 3, Page 706-741, April 2026.ABSTRACT Understanding the biotic and abiotic influences on the deposition and diagenesis of recent microbial carbonates is crucial for addressing the environmental and ecological significance of ancient organosedimentary structures. This study investigates these factors and their expression in the microstructure of Holocene tufa thrombolites from a ...

The role of microorganisms in the formation of a stalactite in Botovskaya Cave, Siberia – paleoenvironmental implications [PDF]
, 2013 Calcitic speleothems in caves can form through abiogenic or biogenic processes, or through a combination of both. Many issues conspire to make the assessment of biogenicity difficult, especially when focusing on old speleothem deposits.

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.Abstract In contrast to previous approaches, new reconstructions of changes in global mean surface temperature and global mean sea level (GMSL) include large variability in GMSL throughout the Pleistocene. Here we assess these reconstructions from an energy balance perspective by using them to force a global carbon cycle model in different scenarios ...

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.Abstract Recent studies have found a dipole pattern of hydroclimate variation in western Asia (WA) and arid central Asia (ACA) during the Holocene. However, speleothem δ18O evidence shows some inconsistencies with other lines of evidence, especially concerning the timing of peak wetness in WA and precipitation trends in ACA.

Origin and distribution of mineral species in limestone caves [PDF]
, 1971 More than 80 mineral species are known to result from secondary chemical reactions in solutional limestone caverns. These minerals are transitional and end-products of carbonate wall rock interactions with ground water and organic residue.

Quaternary, 2019 Here we present an overview of speleothem δ18O records from South America, most of which are available in the Speleothem Isotopes Synthesis and Analysis (SISAL_v1) database.

Paleoclimate in continental northwestern Europe during the Eemian and early Weichselian (125–97 ka): insights from a Belgian speleothem [PDF]
, 2016 The last interglacial serves as an excellent time interval for studying climate dynamics during past warm periods. Speleothems have been successfully used for reconstructing the paleoclimate of last interglacial continental Europe.

Insights into speleothems from lava tubes of the Galapagos Islands (Ecuador): mineralogy and biogenecity [PDF]
, 2016 Different types of hard and soft speleothems (stalactites, stalagmites, columns, crusts, flowstones, micro-gours and botryoidal coralloids) have been observed throughout lava tubes in the Galapagos archipelago, Ecuador.
