Trace element and stable isotope data from a flowstone in a natural cave of the mining district of SW Sardinia (Italy): evidence for Zn2+-induced aragonite precipitation in comparatively wet climatic conditions

International Journal of Speleology, 2011
A speleothem from Crovassa Azzurra, a mine cave in SW Sardinia (Italy), has been analysed for mineralogy, minor and traceelements and stable isotopes. It is composed of layers of primary calcite and aragonite, with a region of secondary calcite.

The glacial cycles and cosmic rays

, 2004
The cause of the glacial cycles remains a mystery. The origin is widely accepted to be astronomical since paleoclimatic archives contain strong spectral components that match the frequencies of Earth's orbital modulation.
