Marine biogenic calcification is the biologically mediated process by which marine organisms produce and deposit calcium carbonate minerals to form skeletal structures or hard tissues.

The ultimate fate, over the course of millennia, of nearly all of the carbon dioxide formed by humankind is for it to react with calcium carbonate in the world's oceans. Although, this …

2021年5月10日 · Calcium carbonate (CaCO 3) minerals secreted by marine organisms are abundant in the ocean. These particles settle and the majority dissolves in deeper waters or at …

2017年10月19日 · Temperature-dependent aragonite and calcite formation by scleractinian corals were examined in low molar (m) Mg/Ca seawater, the experimental conditions replicating the …

2017年7月18日 · In this paper, we dissolve 13 C-labeled calcites in natural seawater. We show that the time-evolving enrichment of 𝜹 13 C in solution is a direct measure of both dissolution …

Calcium carbonates are among the most abundant and reactive minerals on Earth, and their dissolution/preservation in the ocean helps to regulate changes in atmospheric pCO 2.

Here, we investigate the role of aragonite dissolution on the early diagenesis of calcite-rich sediments using a novel 3D, micrometric-scale reactive-transport model combined with 3D, X …

2023年11月15日 · This study documents distinguishable Ca isotopic fractionation during the formation of methane-derived high-Mg calcite and aragonite, providing fundamental …

2009年1月15日 · Our results show that the overall reaction of calcite precipitation in both seawater and NaCl–CaCl 2 solutions is dominated by the following reaction: Ca 2 + + CO 3 2 - …

1980年11月1日 · PDF | The behavior of calcite in typical mixed-layer seawater supersaturated with respect to calcite and aragonite was investigated using saturometry... | Find, read and cite …
