A review on the potentiality of rare earth elements to trace pedogenetic processes
C Laveuf, S Cornu - Geoderma, 2009 - Elsevier
This review aims at considering the use of REEs to trace pedogenetic processes, in order to
quantify the respective contribution of the successive processes on pedogenesis. We first …

Diagenetic uptake of rare earth elements by bioapatite, with an example from Lower Triassic conodonts of South China
The distribution patterns of rare earth elements (REEs) are frequently used as proxies for
ancient seawater chemistry or paleomarine environmental conditions. However, recent work …

Diagenetic constraints on the use of cerium anomalies as palaeoseawater redox proxies: an isotopic and REE study of Cambrian phosphorites
G Shields, P Stille - Chemical Geology, 2001 - Elsevier
Seawater rare-earth element (REE) distributions show heavy REE enrichment and cerium

Did cooling oceans trigger Ordovician biodiversification? Evidence from conodont thermometry
The Ordovician Period, long considered a supergreenhouse state, saw one of the greatest
radiations of life in Earth's history. Previous temperature estimates of up to∼ 70° C have …

Crystal-chemical controls on rare-earth element concentrations in fossil biogenic apatites and implications for paleoenvironmental reconstructions
Fossil biogenic apatites display rare-earth element (REE) patterns which have been
proposed to reflect environmental and biological controls on past seawater composition …

[PDF][PDF] Has the REE composition of seawater changed over geological time?
GA Shields, GE Webb - 2004 - repository.geologyscience.ru
The shale-normalised REE pattern of modern seawater is characterised by two main
features: negative Ce anomalies and relative enrichment of the heavy REE (Fig. 1c). Positive …

Experimentally-controlled carbon and oxygen isotope exchange between bioapatites and water under inorganic and microbially-mediated conditions
Modern bone and enamel powders have reacted at 301 K with 13C-and 18O-labelled
waters under inorganic and microbial conditions. The aim of the study is to investigate the …
