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 …

Marine authigenic carbonates form shallow-water microbialites, mud mounds, and
hydrocarbon-seep deposits and contain appreciable amounts of trace elements that yield …

Rare earth elements and yttrium (REY) have a distinct distribution pattern in seawater, and
this pattern may be faithfully preserved in carbonate sediments and rocks. Anomalous …

The determination of La and Ce anomalies in natural waters, biological samples and
biogenic sedimentary rocks can provide unique information on biogeochemical processes in …

A first study of REE+ Y distribution in a variety of Neoproterozoic (Cryogenian and
Ediacaran) carbonates from different settings in the Saldania, Gariep, Damara and West …

Anthropogenic activities associated with various new technologies are increasingly
disrupting the geochemical cycles of rare earth elements (REEs). For example, samarium …

This chapter focuses almost exclusively on marine evaporites and in particular on how the
chemistry of seawater is reflected in the mineralogy and facies distribution of deposits in …

When cyanobacteria originated and diversified, and what their ancient traits were, remain
critical unresolved problems. Here, we used a phylogenomic approach to construct a well …

Limestone, a major part of the global sedimentary succession, susceptible to post-
depositional diagenesis. Studies of limestone geochemistry are essential in the …

Two units of sedimentary carbonates in association with Neoproterozoic glaciations occur in
the Lantian Formation of the Ediacaran system, equivalent to the Doushantuo Formation …
