Who we are

About the Association

The Association of Applied Geochemists (AAG) is a global community of applied geochemists working across exploration, environment, and analytical research. Founded in 1970, our mission is to advance the science and the people who practice it.

Our purpose

  • Advance the science of geochemistry as it relates to mineral exploration and the environment
  • Facilitate the acquisition, exchange and distribution of scientific knowledge
  • Encourage research and development
  • Sponsor symposia, seminars and technical meetings
  • Support students in applied geochemistry

How we achieve it

  • Publishes the journal Geochemistry: Exploration, Environment, Analysis (GEEA)
  • Publishes the quarterly science newsletter EXPLORE
  • Supports the journal Elements
  • Leads the biennial International Applied Geochemistry Symposia (IAGS)
  • Convenes regional meetings and co-sponsors meetings with other scientific societies
  • Supports students with low membership fees and research and travel grants
  • Provides access to specialized publications, lectures and podcasts
