TLDR
The core Vema 28-238 as discussed by the authors preserves an excellent oxygen isotope and magnetic stratigraphy and is shown to contain undisturbed sediments deposited continuously through the past 870,000 yr.About:

Quaternary marine aminostratigraphy: Perth Basin, Western Australia
TL;DR: The Perth Basin is a narrow, elongate structure with an onshore area of some 45, 000 km2, extending approximately 1000 km along the Western Australian coastline and bounded in the east by the Darling Range.

Karst development and speleogenesis, isla de mona, puerto rico
TL;DR: In this paper, the Lirio Limestone/Isla de Mona Dolomite contact may result from syngenetic speleogenesis and dolomitization rather than preferential dissolution along a lithologic boundary.

Stratigraphy and correlation of the glacial deposits on the Montana Plains
TL;DR: The southernmost limit of late Wisconsin glaciation is in Montana, more than 170 km south of the Lethbridge moraine in Alberta, Canada (Figs 1 and 2) as mentioned in this paper.

Amino-acid racemizarion in Quaternary shell deposits at Willapa Bay, Washington
TL;DR: Extents of racemization (dl ratios) of amino acids in fossil Saxidomus giganteus (Deshayes) and Ostrea lurida Carpenter were measured on shell deposits exposed at 21 sites on the east side of Willapa Bay, Washington as discussed by the authors.

Magnetostratigraphy of Chinese loess–paleosol sequences
TL;DR: In this article, a review of recent developments in loess magnetostratigraphy, including pedostrigraphy based on magnetic susceptibility variations, is presented, highlighting progress in understanding the mechanisms by which the natural remanent magnetization (NRM) is acquired and discuss the fidelity of paleomagnetic recording in Chinese loess records, including the recording of magnetic polarity reversals, excursions, and relative paleointensity variations.

Revised carbonate-water isotopic temperature scale
TL;DR: The relationship between temperature and O(18) content relative to that for a Cretaceous belemnite of the Pee Dee formation previously reported (Epstein, Buchsbaum, Lowenstam, and Urey, 1951) has been re-determined using modified procedures for removing organic matter from shells, and is found to be 16.5 - 4.3 δ + 0.14 δ^2

Insolation changes, ice volumes, and the O18 record in deep‐sea cores
Wallace S. Broecker,Jan van Donk +1 more
TL;DR: In this article, a detailed curve of ice volume versus time is needed in order to test the validity of the hypothesis that changes in the earth's orbital parameters are the cause of oscillations in Pleistocene climate.

Oxygen Isotope Analyses and Pleistocene Temperatures Re-assessed
TL;DR: Oxygen isotope analyses of foraminiferal tests in deep-sea cores have been interpreted as showing that the temperature of seawater in the Caribbean and equatorial Atlantic varied by as much as 6°C during glacial cycles as mentioned in this paper.
Journal ArticleDOI
Carbonate-water isotopic temperature scale
TL;DR: In this article, a relationship between temperature and relative O 18 abundance in calcium carbonate in marine shells has been determined, where the relative abundance of the water in which the shell grew is known, and the temperature can be determined to an accuracy of ± 1.0°C.
