The present overview is intended to point the readers' attention to the important subject of
calcium orthophosphates (CaPO 4). This type of materials is of the special significance for …

Micro-organisms contribute to Earth's mineral deposits through a process known as bacteria-
induced mineral precipitation (BIMP). It is a complex phenomenon that can occur as a result …

Increasing interest in deep-seabed mining has raised many questions surrounding its
potential environmental impacts and how to assess the impacts' significance. Under the …

Subseafloor microbial activities are central to Earth's biogeochemical cycles. They control
Earth's surface oxidation and major aspects of ocean chemistry. They affect climate on long …

The Algerian sedimentary phosphorites of marine origin are located mainly in the Tébessa
region, which is part of the Eastern Saharan Atlas. These phosphorites are hosted by …

Abstract The approximately 2,220–2,060 million years old Lomagundi–Jatuli Event was the
longest positive carbon isotope excursion in Earth history and is traditionally interpreted to …

Rare earth elements (REEs) are commonly used proxies to reconstruct water chemistry and
oxygen saturation during the formation of authigenic and biogenic phosphates in marine …

Several naturally occurring biological materials, including bones and teeth, pathological
calcifications, microbial mineral deposits formed in marine phosphogenesis areas, as well …

Relationships between geological phosphorite deposition and biological apatite nucleation
have often been overlooked. However, similarities in biological apatite and phosphorite …

Rare earth element (REE) analyses are reported on glauconite-bearing phosphorites from
northeastern Algeria. These rocks of Paleocene-Eocene age are located in the Eastern part …
