Climate change and anthropogenic effects on shallow-water carbonate biogeochemistry
… state of surface ocean waters with respect to carbonate minerals will decline during the twenty-first century owing to increasing atmospheric CO2. As a result calcareous organisms could have difficulty calcifying, leading to production of weaker skeletons and their greater vulnerability to …

Dolomite as a paleoenvironmental archive
… evidence for dolomite replacing primary calcium carbonate (CaCO₃) in ancient and modern successions, has prompted the idea that most geologic dolomite formed through diagenetic alteration of CaCO₃, a process that weakens the link between the isotopic signals held by the primary carbonate and …

MAJOR AND MINOR ION GEOCHEMISTRY OF GROUNDWATERS FROM BERMUDA
… studied for variations in major and minor ion geochemistry. Factors which influence groundwater geochemistry include Ghyben-Herzberg/freshwater-seawater mixing, carbonate dissolution and recrystallization, redox and the hydrology. The major ions calcium, magnesium and strontium have been …

Investigating Telogenetic Karst Aquifer Processes and Evolution in South-Central Kentucky, U.S., Using High-Resolution Storm Hydrology and Geochemistry Monitoring
<p>Recent studies have investigated the hydrological and geochemical characteristics of karst aquifers in different settings; however, telogenetic karst aquifer processes remain poorly understood. In south-central Kentucky, the iconic Lost River Cave and Valley represents a large, complex …

Timing and Source of Alkali Enrichment at Mt. Etna, Sicily: Constraints from Clinopyroxene Geobarometry and In Situ SR Isotope Data
… between ~8.7 and 16.5 km within the volcano’s carbonate substratum. A select population of clinopyroxene exhibits increasing weight percent CaO and Mg# with decreasing pressure, providing new evidence for late-stage carbonate assimilation enhanced by magmatic recharge. Alkali-enrichment is thus …
