RECENT INVESTIGATION

During my Ph.D., I investigated the post-caldera pyroclastic activity of the La Primavera caldera in Mexico. Through detailed field observations, grain size and componentry analysis, geochemical studies, and U/Th radiometric dating, I identified and correlated the deposits of 14 explosive eruptions with their source volcanoes within the caldera. By integrating stratigraphic relationships between pyroclastic deposits and lava flows, new radiometric ages, and geochemical data, I refined the evolutionary model of the volcanic complex (Sourisseau et al., 2020). Additionally, I analyzed the geochemical composition of post-caldera pyroclastic units to gain insights into the magmatic processes responsible for the generation of La Primavera magmas (Sourisseau et al., 2023).

My present research focus on:

  • Holocene pyroclastic activity of the Colli dome, La Primavera caldera, Jalisco, Mexico.
  • Pyroclastic stratigraphy of the S-SW sector of the Pico de Orizaba volcano, Puebla-Veracruz, Mexico.
  • Tephrostratigraphy of the Totolcingo Lagoon, Serdan Oriental Basin, Mexico.

      RESEARCH INTERESTS

      • Reconstruction of volcanic histories by analyzing the relationships between pyroclastic deposits and lava flows, as well as through componentry analysis, geochemistry, and radiometric dating.
      • Reconstruction of past pyroclastic eruptions to better understand their dynamics and impacts.
      • Identification, description, and correlation of tephra deposits from lacustrine, marine, and glacial environments (e.g., DSDP, ODP, and IODP expeditions) with their source volcanoes. This work aims to establish detailed eruption frequency records, refine our understanding of large-magnitude volcanic events, and enhance correlations with paleoenvironmental archives.
