History & Mission

The Society

The Society of Economic Geologists, Inc., (SEG) is an international organization of individual members with interests in the field of economic geology. The Society's membership includes representatives from industry, academia, and government institutions. Annual meetings, publications, field conferences, and short courses ensure an active communication of economic geology-related concepts within the membership and with the economic geology profession at large. An individual may apply for membership as Fellow, Member or Student Member.


SEG originated from a 1919 gathering of a group of Geological Society of America (GSA) members who were especially interested in economic geology. The Society was established on December 28, 1920, during a constituting meeting of 60 distinguished professionals, including A.M. Bateman, W.H. Emmons, L.C. Graton, J.F. Kemp, A.C. Lawson, W. Lindgren, R.A.F. Penrose, Jr., R.H. Sales, J.E. Spurr and H.V. Winchell. Today the Society consists of more than 7000 members residing in over 90 countries throughout the world.


The objectives of the Society are as follows:

  • To advance the science of geology through the scientific investigation of mineral deposits and mineral resources and the application thereof to exploration, mineral resource appraisal, mining and mineral extraction.
  • To disseminate basic and applied scientific information arising from investigations of mineral deposits and mineral resources through SEG publications, meetings, symposia, conferences, field trips, short courses, workshops and lecture series.
