Calcite Mg and Sr partition coefficients in cave environments: Implications for interpreting prior calcite precipitation in speleothems

“…In addition to mixed host rock cave settings, other sources may also contribute to changes in the initial Mg/Ca and Sr/Ca ratios of the drip water. Examples include volcanic ash deposits (Jamieson et al, 2015), aerosol settling under dry climate conditions within the cave (Dredge et al, 2013), wind-blown dust (Zhou et al, 2008), and the balance between Sr derived from the soil versus Sr derived from the host rock (Wortham et al, 2017). Mg-and Sr-isotope analysis is a valuable tool to identify different sources of these elements (Oster et al, 2010;Riechelmann et al, 2012;Weber et al, 2017).…”

“…The most frequently used proxies are carbon and oxygen isotopes as well as trace elements (Baldini et al, 2015;Griffiths et al, 2010;Moseley et al, 2014). Speleothem trace element variability, however, may depend on a complex set of processes, and may be affected by different sources or transport and incorporation mechanisms, such as the presence of colloids (Hartland et al, 2012), aerosols (Dredge et al, 2013) and volcanic ash (Jamieson et al, 2015). This makes their interpretation occasionally challenging (Fairchild and Treble, 2009).…”

Last glacial climate oscillations and sudden environmental changes investigated in stalagmites from southwest Sulawesi, western Pacific

“…Cave carbonate mineral deposits, also known as speleothems, provide a unique opportunity to reconstruct climate changes, human evolution, recurrence patterns of paleoseismic events, and volcanic eruptions (e.g., Wang et al, 2001;Zhao et al, 2001;Fleitmann et al, 2004Fleitmann et al, , 2009Kagan et al, 2005;Tuccimei et al, 2006;Frisia et al, 2008;Wynn et al, 2008;Siklosy et al, 2009;Badertscher et al, 2014;Jamieson et al, 2015). While the importance of speleothems as archives of climate change has been well established, their role in the reconstruction of Earth's volcanism is still in its infancy.…”

Reconstructing seasonality through stable isotope and trace element analysis of the Proserpine stalagmite, Han-sur-Lesse Cave, Belgium: indications for climate-driven changes during the last 400 years

“…The use of trace elements brings additional information that can be used to unravel seasonal variability in speleothem chemistry. Examples of this include the use of trace element concentrations as proxies for precipitation (Baldini et al, 2002;Warken et al, 2018), soil processes (Regattieri et al, 2016) or changes in sediment supply (Regattieri et al, 2016) and can be used to identify volcanic ash fall events from speleothem records (Jamieson et al, 2015).…”
