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 …

Over the past century a number of models have been developed to explain the vast
stratigraphic distribution of authigenic dolomite. These models include hydrogeological …

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 …

Although deep carbon recycling plays an important role in the atmospheric CO2 budget and
climate changes through geological time, the precise mechanisms remain poorly …

For the first four billion years of Earth's history, climate was marked by apparent stability and
warmth despite the Sun having lower luminosity. Proposed mechanisms for maintaining an …

Shallow-water carbonate sediments constitute one of the most abundant and widely used
archives of Earth's surface evolution. One of the main limitations of this archive is the …

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 …

Deep carbon cycle is crucial for mantle dynamics and maintaining Earth's habitability.
Recycled carbonates are a strong oxidant in mantle carbon-iron redox reactions, leading to …

Groundwater-derived solute fluxes to the ocean have long been assumed static and
subordinate to riverine fluxes, if not neglected entirely, in marine isotope budgets. Here we …

Calcite growth experiments have been performed in the presence of aqueous Mg at 25° C
and 1bar pCO2 to quantify magnesium partition coefficient DMg=(Mg/Ca) solid (Mg/Ca) fluid …
