The distribution patterns of rare earth elements (REEs) are frequently used as proxies for
ancient seawater chemistry or paleomarine environmental conditions. However, recent work …

Fluorapatite (FAp, nominally Ca5 (PO4) 3F) is the most common phosphate mineral at the
Earth's surface and a main host for rare-earth elements (REE) in magmatic and …

The factors influencing goethite to magnetite conversion during magnetizing roasting of an
iron-rich rare earth ore using coal as the reductant were explored in the present paper. The …

The ecogeochemistry is the application of geochemical features to study animal ecology.
This approach is promising for using in reconstructions of ancient pelagic ecosystems …

An isotopic investigation of organic matter of the Late Devonian-Carboniferous
(Mississippian) conodont elements of various morphology was carried out. δ 13Corg values …

Conodont elements composed of protein-apatite nanocomposites are considered a
promising geochemical archive due to their high resistivity to weathering and diagenetic …

Conodont elements are calcium phosphate (apatite structure) mineralized remains of the
cephalic feeding apparatus of an extinct marine organism. Due to the high affinity of apatite …

Conodonts were the Palaeozoic and Triassic extinct group of the marine animals
possessing discussed affinities. The only mineralized parts of conodonts are tooth-like …

Detailed geochemical and mineralogical insights into some of the richest rare earth
elements and yttrium (REY)-containing bioapatites from ocean-floor sediments have been …

The δ13Corg values and their variations in conodont elements of the latest Famennian–
Tournaisian species Polygnathus parapetus Druce are considered. The conodonts studied …
