Research Interests

  • Development of late-stage petrocalcic horizons in arid and semi-arid regions.
  • Linkage of geomorphic, tectonic, and paleoclimatic changes to pedogenesis in ancient soils.
  • The mode and timing of pedogenic silicate clay and barite formation in ancient carbonate soils.
  • Soil mineralogy and micromorphology.

 

Grants/Projects
