Geochemistry of core sediments from the southeast coast of Bangladesh: Implications for provenance and chemical weathering intensity

Geochemical analyses of major oxides, trace, and rare-earth elements (REE) were examined on the ~70 m core sediments collected from the southeast coast of Bangladesh to determine sediment provenance, maturity, and chemical weathering conditions. The sediment samples contained high SiO2 (62-91 wt.%) and low Al2O3 (~5-17 wt.%) contents and showed a ...

Mineralogical and chemical changes of soil and stream sediment formed by intense weathering of the Danburg granite, Georgia, U.S.A.

Lithos, 1988
Abstract A series of soil and stream sediments developed during intense weathering on the metaluminous Danburg granite, northeastern Georgia, U.S.A., have been analyzed mineralogically and chemically. The concentrations of Ba, Na, Rb and Cs in the silt and coarser fractions are controlled mainly by feldspars and biotite.

Low chemical weathering intensity in the Vøring Basin during the Paleocene-Eocene Thermal Maximum

The Paleocene Eocene thermal Maximum (PETM) was a rapid global warming event, which occurred ~ 56 million years ago and lasted for ~200 ka. It is characterized by a massive rapid input of 13C-depleted carbon into the atmosphere and ocean, causing a 2-7‰ negative carbon isotope excursion (CIE).
