A New Symbol for a Great Vision
The new GSA logo is a graphical representation of Earth in space. It reflects the expansion that has taken place within the geological sciences. Geoscience is no longer limited to earthbound, hard-rock geology, but includes planetary geology and the integration of other scientific disciplines such as biology, chemistry, atmospheric science, and oceanography.
The new logo also reflects increased research activity by GSA members outside of North America and the growing number of non-United States-based GSA members. It supports the Society's globalization initiative.
Inside the Design
Visual description of new GSA logo.

The green portion in the lower half depicts a portion of the globe. Its undifferentiated surface allows for assumed inclusion of the lithosphere, asthenosphere, hydrosphere, and biosphere, along with the many scientific disciplines involved in their study.
The white area represents Earth's atmosphere, communicating inclusion of atmospheric sciences.
The deep purple at the top represents space and the attendant planetary disciplines that are a vital part of the geosciences.
The name element of the mark makes clear that this expanded view of the geosciences is held by the Geological Society of America.
While the geosciences have expanded in scope, and GSA as a society has moved beyond the boundaries of North America and hard-rock geology, the name element strongly states both our scientific orientation and our organizational identity.
