Late Quaternary climatic changes on the south-western Balearic slope (Western Mediterranean): Isotopic, faunal and mineralogical relationships
We report the results of a research on the carbonate mineralogy, planktonic foraminifera distribution, and oxygen and carbon isotope composition of G. bulloides in hemipelagic carbonate oozes of the Southwestern-Balearic Slope (Western Mediterranean) to contribute to the understanding of climatic an...
