GeoMiner for Geologists

GeoMiner brings practical geology workflows into one free platform for working geologists, students, educators, and field teams. Use photo-assisted specimen screening for hand samples, outcrops, drill core, and thin sections; record core intervals, alteration, mineralization, structure, mapping stations, sample identifiers, QA/QC details, and production observations; and export field records for further review. The reference library, comparison guides, and training tracks support onboarding, field-school preparation, petrography teaching, and public outreach. AI-assisted results remain preliminary and should be checked against field evidence, site procedures, and appropriate professional or laboratory methods.

  • All free GeoMiner features — See identification, learning, reference, community, classroom, and field tools together.
  • Partner with GeoMiner — Discuss earth-science education, workforce awareness, technical collaboration, or sponsorship.
