Magnesium (Mg) has an atomic number of 12 and belongs to the alkaline earth element
(Group II) of the Periodic Table. The pure Mg is a silvery white metal and has a melting point …

Hundreds of coral paleoclimate records have been developed over the past several
decades, significantly extending the instrumental record and improving our understanding of …

Shallow-water carbonate sediments constitute the bulk of sedimentary carbonates in the
geologic record and are widely used archives of Earth's chemical and climatic history. One …

Stable carbon and oxygen isotopes (δ18O and δ13C values) and trace elements have been
applied to the study of diagenesis of carbonate rocks for over 50 years. As valuable as these …

Dolomite precipitation models and kinetics are debated and complicated due to the complex
and temporally fluctuating fluid chemistry and different diagenetic environments. Using well …

Geochemical variations in marine biogenic carbonates that are preserved in the geological
record serve as proxies of past environmental change. However, interpreting most proxies is …

The beginning of the Ediacaran Period (∼ 635 Ma) is marked by conspicuous dolostone
units that cap Marinoan glacial deposits worldwide. The extent and sedimentary …

Measurements of B/Ca ratios in marine carbonates have been suggested to record seawater
carbonate chemistry, however experimental calibration of such proxies based on inorganic …

Available Mg isotope data indicate that dolostones of different ages have overlap** range
of Mg isotopic composition (δ 26 Mg) and there is no systematic difference among different …

Neoproterozoic cap carbonates host distinctive geochemical and sedimentological features
that reflect prevailing conditions in the aftermath of Snowball Earth. Interpretation of these …
