      Volcanic CO2 output at the Central American subduction zone inferred from melt inclusions in olivine crystals from mafic tephras

      H. Wehrmann, K. Hoernle, M. Portnyagin, M. Wiedenbeck and K. Heydolph

      Version of Record online: 14 JUN 2011 | DOI: 10.1029/2010GC003412

      Key Points

      • CO2 concentrations determined in mafic melt inclusions from the CAVA by SIMS
      • CO2 degassing pathways substantiate subduction water fluxes
      • CO2 output flux from the mantle wedge at the CAVA: 2.8 × 104 g/s

      Arc-parallel shear deformation and escape flow in the mantle wedge of the Central America subduction zone: Evidence from P wave anisotropy

      W. Rabbel, I. Koulakov, A. N. Dinc and A. Jakovlev

      Version of Record online: 7 JUN 2011 | DOI: 10.1029/2010GC003325

      Key Points

      • The upper mantle of the Central America subduction zone is anisotropic
      • In the fore arc P wave anisotropy is arc-parallel
      • P wave anisotropy indicates escape flow in agreement with GPS and S waves
