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:

Pedostratigraphy of Chinese loess deposits and climatic cycles in the last 2.5 Myr
TL;DR: The most complete and distinct loess-paleosol sequence occurs in the Baoji section of the southern part of the Loess Plateau as mentioned in this paper, which represents thirty seven major cold to warm climatic cycles in the last 2.5 Myr.

Correlation of the Eemian (interglacial) Stage and the deep-sea oxygen-isotope stratigraphy
TL;DR: In this paper, a complete interglacial sequence in coastal marine sediments in western Norway is correlated with the Eemian Stage by means of pollen stratigraphy, and with deep-sea cores with marine fossils.
22. quaternary oxygen isotope record of pelagic foraminifers: site 806, ontong java plateau1
T. Bickert,H. Schmidt,G. Wefer +2 more
TL;DR: In this article, an oxygen isotope record that can serve as a new standard for Quaternary chronology in the western Pacific was presented, and the Brunhes/Matuyama boundary was estimated at 792 ka (± 10 k.y.).

Brunhes time scales and the interpretation of climatic change
TL;DR: In this article, two new δ18O time scales have been developed for the Brunhes Epoch using equatorial Pacific core V28-238 using continuous strip-sample technique, the first is based on a constant accumulation rate of aluminum, an assumption which has been shown to be acceptable for the last 360,000 years of the record by comparison with 230Th ages determined via the continuous strip sample technique.

Plio-quaternary vertical motions and the subduction of the Nazca ridge, central coast of Peru
José Macharé,Luc Ortlieb +1 more
TL;DR: In this article, it was shown that the Andean deformation of the coastal area between Pisco and Lomas is characterized by a quite continuous sequence of uplift events progressing southwards, and that the strongest uplift has been occurring immediately south of the inland projection of the Nazca Ridge.

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.
