TL;DR: High-resolution determinations of crustal properties along the spreading center were made to gain knowledge of the source of new oceanic crust and marine magnetic anomalies, the nature of the axial magma chamber, and the depth of hydrothermal circulation.

TL;DR: The experimental replacement of calcite and aragonite by dolomite under a variety of conditions indicates that dolmitization can take place in marine and lacustrine environments under two conditions: low dissolved sulfate concentrations and insubstantial contemporary silica diagenesis.

TL;DR: In this article, a solution-redeposition mechanism is employed in the opal-A-to-opal-CT transformation in deep-sea sediments, showing that the transformation rate is much higher in carbonate-rich sediments than in clay-rich ones.

TL;DR: A comparison between seawater sulfate and marine carbonate carbon isotope records reveals no clear systematic coupling between the sulfur and carbon cycles over one to several millions of years, indicating that changes in the burial rate of pyrite sulfur and organic carbon did not singularly control the atmospheric oxygen content over short time intervals in the Cenozoic.

TL;DR: An empirical correlation between marine barite (BaSO4) accumulation rate in core-top sediment samples from two equatorial Pacific transects (at 140°W and 110°W) and the estimated primary productivity of the overlying water column were used to evaluate glacial to interglacial changes in productivity as discussed by the authors.
