Our on-line inventory dataset includes sample material from oil and gas wells, mineral prospects, surface samples, and additional metadata for most archived samples. The interactive inventory interface allows users to quickly view details of the sample repository before visiting the facility. If you do not find materials appropriate to your research needs, please contact GMC staff for help. We have search capabilities not available through the web search interface.

Pre-arrange details of your visit with the GMC Curator.

The GMC offers both public and private viewing rooms, overhead "daylight" track lighting, counters, sinks, LED stereoscopes, and digital balances. Visitors may bring their own specialty equipment, personal Wi-fi access must be pre-arranged with the Curator before the visit. High quality Zeiss petrographic and stereographic microscopes with a high quality photographic attachment are available separately. No samples may be taken.

Analyze Samples

Removal of material for analysis must be approved by the GMC Curator. Investigators should submit an abstract of the proposed sampling plan that includes justification of scientific work and a detailed sample plan. The Curator will examine the scientific merit for use of a finite sample resource and determine if there are sufficient materials to achieve valid analytical results. All data results and unused remaining materials must be returned to the GMC within 9 months of the sample date.
