Paleotemperature Changes in the Upper and Middle Pleistocene [PDF]

Eiszeitalter und Gegenwart, 1967
By the combination of land and sea data the author came to the conclusion that the duration of the Middle and Upper Pleistocene glacial ages was of the same order of magnitude.

Ikaite nucleation at 35 degrees C challenges the use of glendonite as a paleotemperature indicator [PDF]

, 2020
Glendonites have been found worldwide in marine sediments from the Neoproterozoic Era to the Quaternary Period. The precursor of glendonite, ikaite (CaCO3 · 6H2O), is metastable and has only been observed in nature at temperatures <7 °C.

Measurement of Paleotemperature

The Quaternary Research (Daiyonki-Kenkyu), 1967
Principle and experimental method of paleotemperature analysis were reviewed. The temperature coefficient of equilibrium constant of exchange reaction of oxygen atom between water and carbonate is large enough to enable us to calculate temperature of formation of carbonate in water.

MODELLING OF PHANEROZOIC FOCI OF HYDROCARBON GENERATION TO ASSESS THEIR ROLE IN FORMATION OF THE PALEOZOIC OIL DEPOSITS (SOUTHEASTERN OF WESTERN SIBERIA)

Известия Томского политехнического университета: Инжиниринг георесурсов, 2021
The relevance. Commercially producible volumes of oil and gas from the Paleozoic play are defined within all territory of Western Siberia. Extensive work to assess the amount of the pre-Jurassic hydrocarbon resources was performed in southeastern.

Oxygen Depletion in Lake Waters May Skew brGDGT‐Inferred Temperatures by More Than 10°C

Geophysical Research Letters
Branched glycerol dialkyl glycerol tetraether (brGDGT) paleothermometry is an important tool for paleoclimate research. Oxygen availability has been suggested to skew brGDGT‐inferred temperatures, but the effect is poorly constrained.

Dead Sea Warming and the Origin of Salt Giants

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Episodically in Earth's history, marine basins became hydrologically restricted, forming “salt giants,” yet the mechanisms driving their formation remain debated. The modern Dead Sea, undergoing restriction from anthropogenic inflow diversion, shows rapid lake‐level decline and salt precipitation.

Planktonic foraminiferal Mg/Ca as a proxy for past oceanic temperatures: a methodological overview and data compilation for the Last Glacial Maximum [PDF]

, 2005
As part of the Multi-proxy Approach for the Reconstruction of the Glacial Ocean (MARGO) incentive, published and unpublished temperature reconstructions for the Last Glacial Maximum (LGM) based on planktonic foraminiferal Mg/Ca ratios have been ...
