Overview

This research uncovers volcanic activity linked to deglaciation in southern Chile, indicating changes in melting processes.

Key Points

  • The aim is to investigate the volcanic activity at Carrán-Los Venados and its connection to post-glacial melting processes.
  • Analysis of trace element characteristics and U-series isotopes
  • Examination of olivine textures and chemistry
  • Assessment of eruption styles and temporal changes in the volcanic field
  • Older Basal Lavas show dampened subduction influence and higher melting rates
  • Evidence of longer storage times for Basal Lavas compared to Holocene tephras
  • Historic eruptions reveal a uniform composition, indicating a developing storage system in the lower crust
