Investigation of Mg and Sr Distribution in Speleothem

Abstract

<p> The distribution of Mg and Sr in speleothem from Yorkshire, England, Vancouver Island and West Virginia, was investigated. Concentrations of Mg range from 300 to greater than 3000 parts per million. Concentrations of Sr range from less than 100 to a few hundred parts per million. Sr partitioning between seepage water and calcite may be more rate sensitive than Mg partitioning.</p> <p> It is possible that Mg and Sr in speleothem could provide information on kinetics and mechanism of speleothem formation and on seepage water and source rock composition.</p> <p> It may be possible to interpret Mg concentration in speleothem in terms of temperature if equilibrium partitioning of Mg between calcite and seepage waters can be demonstrated.</p>
