Lead (Pb) fluxes and Pb isotopic compositions from Masaya Volcano, Nicaragua

Abstract:

We report Pb concentrations and isotopic compositions measured in plume aerosol and Pele's hair (lava) samples collected from Masaya volcano, Nicaragua, to provide the first data pertaining to Pb emissions from the Central American volcanic arc. Lead isotopic compositions, determined by Thermal Ionisation Mass Spectrometry, in the Pele's hair samples were found to be 206Pb/ 207Pb∼1.196, 208Pb/207Pb∼2.46 and 206Pb/204Pb∼18.6. Mean Pb fluxes from Masaya were calculated to be 1.0ton Pbyr-1 with ...
