Welcome to American Journal of Science

About American Journal of Science

We are in transition to a new hosting server. Please access to https://ajs.scholasticahq.com/ for latest articles and old archives. AJS is now a Diamond Open-Access journal, and all articles are available without subscription.

Focus

AJS publishes research that expands our knowledge of the Earth, with an emphasis the study of the structure, composition, and evolution of our planet, and the physical, chemical, and biological processes that have influenced its evolution. Recent papers have focused on geochemistry, geochronology, geodynamics, geomorphology, basin analysis, Earth history, petrology, tectonics, and thermochronology, but new directions are welcomed.

Changes Starting in 2023

  • Diamond Open-Access model: Authors can publish standard-length papers for free, and readers have free access to all our publications.
  • Web-based submission system (Submit your paper)
  • New journal format
