Water plays a critical role in erosion and sediment transport and this relationship is most
evident in the hyperarid Atacama Desert of Northern Chile, a region characterized by …

Carbonate minerals have precipitated from seawater for at least the last 3.8 billion years, but
changes in the physical and chemical properties of carbonate rocks demonstrate that the …

Phosphorus is a limiting nutrient that is thought to control oceanic oxygen levels to a large
extent,–. A possible increase in marine phosphorus concentrations during the Ediacaran …

Anoxic and iron-rich oceanic conditions prevailed throughout most of the Archean and
Proterozoic (4000 to c. 540 million years ago, Ma), but the oceans are hypothesised to have …

The central part of the Sichuan Basin shows an excellent exploration potential in the
dolomitized microbial reservoirs of the Dengying Formation. However, the influence of …

Marinoan cap carbonates are the first sedimentary rocks deposited after the Marinoan
Snowball Earth glaciation and likely record the marine geochemical signals across the …

Neoproterozoic marine dolomite cements represent reliable, albeit complex, archives of their
palaeoenvironment. Petrological and high‐resolution geochemical data from well …

Fibrous carbonate cement is a common phase in marine phreatic environments—but its
origin and diagenetic history are underexplored. This paper compares two fibrous fabrics …

Abstract The terminal Ediacaran Khatyspyt Lagerstätte (ca. 550–544 Ma) of Arctic Siberia
has been a prime target for geobiological research. Previous evidence suggested that …

The history of oceanic oxygenation from the late Neoproterozoic to the early Cambrian is
currently debated, making it difficult to gauge whether, and to what extent environmental …
