Abstract “Old phosphorite” deposits (Ediacaran to early Cambrian) located in Central
Guizhou, South China, are hosted in carbonate and represent the earliest phosphogenesis …

The rare earth elements and yttrium (REY) in bioapatite from deep-sea sediments are
potential proxies for reconstructing paleoenvironmental conditions. However, the REY …

Recently, rare-earth elements and yttrium (REYs, including La-Lu and Y) have been found to
be remarkably enriched in Pacific and Indian Ocean deep-sea sediments, as the extreme …

Rare earth elements (REE) and yttrium (Y), termed as REY, are recently found to be
extremely enriched in some pelagic sediments, which could be an important resource for …

Fossil biogenic apatites display trace element (TE) compositions that can record
environmental and biological signals, give insights into past water compositions, or be used …

Intra-bone rare earth element (REE) fractionation trends were studied by LA-ICPMS analysis
to put constraints on (1) the mechanisms controlling REE fractionation within fossil bones;(2) …

Strontium isotope ratios measured in fossil human teeth are a powerful tool to investigate
past mobility patterns. In order to apply this method, the sample needs to be investigated for …

Biomineralized tissues are chemically altered after death, and this diagenetic alteration can
obscure original biological chemical features or provide new chemical information about the …

Abstract The Late Paleocene–Early Eocene phosphorites of the Metlaoui Group in Tunisia
are a world-class phosphate resource. We review the characteristics of phosphorites …

In deep sea sediments, rare earth elements and yttrium (REYs) are predominantly carried by
bioapatite and Fe-Mn (oxyhydr) oxides. According to recent studies, REYs can migrate into …
