TLDR
In this article, the elemental proxies for palaeoclimatic and palaeoceanographic variability in marine sediments are discussed, and the application of sedimentary geochemistry to the reconstruction of climatic and oceanographic changes over the Cenozoic is discussed.
Abstract
Publisher Summary This chapter discusses the elemental proxies for palaeoclimatic and palaeoceanographic variability in marine sediments. Physical and biological processes during deposition coupled with post-depositional chemical reactions yield a complex component mixture that can provide significant palaeoceanographic and palaeoclimatic information to complement and strengthen interpretations derived from the study of microfossils and the isotopic compositions of sedimentary components. The chapter reviews the application of sedimentary geochemistry to the reconstruction of climatic and oceanographic changes over the Cenozoic, with emphasis on the Late Pleistocene. Records from both pelagic regimes and ocean margin provinces are used to show how information on both ocean conditions and terrestrial climates can be assembled from the major, minor and trace element composition of sea-floor deposits. The chapter provides background sedimentary information, and describes some common data manipulation techniques that are used to construct and study palaeoclimatic and palaeoceanographic records in marine sediments.

Calibration of XRF core scanners for quantitative geochemical logging of sediment cores: Theory and application

TL;DR: In this paper, a log-ratio calibration model for XRF core scanners is proposed, which is derived from a combination of XRF-spectrometry theory, principles of compositional data analysis, and empirical evidence.

Total organic carbon, organic phosphorus, and biogenic barium fluxes as proxies for paleomarine productivity

TL;DR: In this paper, the accumulation rates of three commonly used proxies for productivity from a set of primarily Quaternary sediment cores at 94 marine sites, compiled from 37 published sources, were evaluated for total organic carbon, organic phosphorus, and biogenic barium (Babio).

Links between iron supply, marine productivity, sea surface temperature, and CO2 over the last 1.1 Ma

TL;DR: In this article, the authors present a new multiproxy data set of sea surface temperatures (SST), dust and iron supply, and marine export productivity from the marine sediment core PS2489-2/ODP Site 1090 located in the subantarctic Atlantic, that allow them to evaluate various hypotheses on the role of the Southern Ocean (SO) in modulating atmospheric CO2 concentrations back to 11 Ma.

A marine biogeochemical perspective on black shale deposition

TL;DR: In this paper, the authors used the V:Mo ratio in the marine fraction of the Kimmeridge Clay Formation to hindcast the hydrography and biogeochemical conditions of deposition of a black shale of Late Jurassic age from its trace metal and organic carbon content.

Tracing bottom water oxygenation with sedimentary Mn/Fe ratios in Lake Zurich, Switzerland

TL;DR: In this paper, the authors studied the redox dynamics of manganese (Mn) in the sediment of Lake Zurich using precise sediment core age models, monthly long-term oxygen (O 2 ) monitoring data of the water column (1936-2010) and high-resolution XRF core scanning.

The continental crust: Its composition and evolution

TL;DR: In this paper, the authors describe the composition of the present upper crust and deal with possible compositions for the total crust and the inferred composition of lower crust, and the question of the uniformity of crustal composition throughout geological time is discussed.

Early Proterozoic climates and plate motions inferred from major element chemistry of lutites

TL;DR: The early Proterozoic Huronian Supergroup of the north shore of Lake Huron (Fig. 1) is a thick succession of sedimentary and volcanic rocks deposited between about 2,500 and 2,100 Myr ago as discussed by the authors.

A 17,000-year glacio-eustatic sea level record: influence of glacial melting rates on the Younger Dryas event and deep-ocean circulation

TL;DR: In this paper, a global oxygen isotope record for ocean water has been calculated from the Barbados sea level curve, allowing separation of the ice volume component common to all isotope records measured in deep-sea cores.
