The Use of Submerged Speleothems for Sea Level Studies in the Mediterranean Sea: A New Perspective Using Glacial Isostatic Adjustment (GIA)

Geosciences (Switzerland), 2021
The investigation of submerged speleothems for sea level studies has made significant contributions to the understanding of the global and regional sea level variations during the Middle and Late Quaternary.

Ni-rich mineral nepouite explains the exceptional green color of speleothems [PDF]

Scientific Reports, 2023
Speleothems are secondary mineral structures typically found in karstic caves and usually composed of calcite or aragonite. Despite being naturally white, some might exhibit unusual colors, such as blue, black, red, yellow or green.

Stalactites Core Prospect as Environmental “Microbial Ark”: The Actinomycetota Diversity Paradigm, First Reported from a Greek Cave [PDF]

Polish Journal of Microbiology, 2023
Speleothems found in caves worldwide are considered the natural libraries of paleontology. Bacteria found in these ecosystems are generally limited to Proteobacteria and Actinomycetota, but rare microbiome and “Dark Matter” is generally under ...

Speleothem microstructure/speleothem ontogeny: a review of Western contributions

International 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 ...

Deep submerged speleothems in the Sansha Yongle Blue Hole (South China Sea) as determination of low sea levels during the Last Glacial Maximum

Frontiers in Marine Science, 2022
Although Last Glacial Maximum (LGM) sea levels have been the focus of much attention in climate and marine sciences, the timing, duration, and magnitude need further research.

Application of microbial membrane tetraether lipids in speleothems

Frontiers in Ecology and Evolution, 2023
Glycerol dialkyl glycerol tetraethers (GDGTs), which are derived from microbial membranes, occur widely in soils, peats, lake sediments, marine sediments, hot springs, and other environments.

GEOMAGNETIC EXCURSION RECORD PRESERVED IN THE SPELEOTHEM FROM WESTERN CAUCASUS: FIRST DATA

Геодинамика и тектонофизика, 2022
The study of the geomagnetic field evolution on minor timescales, in particular of such significant events as geomagnetic reversals and excursions, has acquired particular relevance nowadays due to the increased attention of mankind to the environment ...
