The Oceanic Chemistry of the Rare-Earth Elements [and Discussion]

Because of the unique chemical characteristics of the rare-earth elements (REES), they provide information as oceanic tracers of element source and reactivity. The absolute and relative concentrations of the REES in ocean waters reflect ...

Iron Formation: The Sedimentary Product of a Complex Interplay among Mantle, Tectonic, Oceanic, and Biospheric Processes

Iron formations are economically important sedimentary rocks that are most common in Precambrian sedimentary successions. Although many aspects of their origin remain unresolved, it is widely accepted that secular changes in the style of...

Rare earth element and Nd isotopic variations in regionally extensive dolomites from the Burlington-Keokuk Formation (Mississippian); implications for REE mobility during carbonate diagenesis

These carbonates of the midcontinent region have been subject to two major episodes of regionally extensive (100 000 km 2) dolomitization. A consistency in the Nd isotope ratios and REE patterns, along with the presence of anomalously lo...
