Speleothem microstructure/speleothem ontogeny: a review of Western contributions

open access: yesInternational Journal of Speleology, 2012
Mineral ontogeny is the study of the growth and development of mineral deposits in general and, in the present context, speleothems in particular. Previous researchers, mainly in Russia, have developed a nomenclatural hierarchy based on the forms and ...

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.

Heterogenous Late Holocene Climate in the Eastern Mediterranean—The Kocain Cave Record From SW Turkey

open access: yesGeophysical Research Letters, 2021
Palaeoclimate variability must be constrained to predict the nature and impacts of future climate change in the Eastern Mediterranean. Here, we present a late Holocene high‐resolution multiproxy data set from Kocain Cave, the first of its kind from SW ...

Proxy Response Heterogeneity to the Indian Monsoon During Last Millennium in the Himalayan Region

open access: yesFrontiers in Ecology and Evolution, 2022
We reviewed the available climate records for the past 2 millennia based on the analyzed sediment and speleothem archives from different regions of South Asia. Speleothem records from the core-monsoon regions of the Indian sub-continent have revealed the

Spatio-temporal dynamics of speleothem growth and glaciation in the British Isles [PDF]

open access: yesClimate of the Past
Reconstructing the spatio-temporal dynamics of glaciations and permafrost largely relies on surface deposits and is therefore a challenge for every glacial period older than the last due to erosion.

Говийн aгуйн спелеотемын судалгааны үр дүн ба эртний уур амьсгал

open access: yesProceedings of the Mongolian Academy of Sciences, 2017
No Mongolian AbstractSpeleothems have been found out in three caves: the Shar-khanan , Gurvan-Zeerd and Lovon-Chombo. Were dated by U-Th method. No speleothem deposition younger than 550 ky was found in the Gobi .

Petrographic and geochemical constraints on the formation of gravity‐defying speleothems

open access: yesThe Depositional Record, 2023
Cave carbonates, seemingly growing in defiance of gravity, have attracted the community's interest for more than a century. This paper focusses on ‘helictites’, contorted vermiform speleothems with central capillaries.

Early and mid-holocene environmental conditions in the eastern Adriatic recorded in speleothems from Mala Špilja cave and Velika Špilja cave (Mljet island, Croatia)

open access: yesActa Carsologica, 2017
This study presents high resolutionoxygen and carbon isotopic record of two U-Th dated stalagmites from the Eastern Adriatic caves. The stalagmites were collected from Mala špilja and Velika špilja caves situated on Mljet Island in the southern part of ...

Active growth of non-hydrothermal subaqueous and subaerial barite (BaSO4) speleothems in Lechuguilla Cave (New Mexico, USA)

open access: yesInternational Journal of Speleology, 2020
Barite (BaSO4) speleothems have been reported from caves around the globe and interpreted to have chiefly formed in phreatic, hypogene, hydrothermal settings.
