Horace R. Collins Laboratory & Core Repository
Horace R. Collins Laboratory & Core Repository

The ODNR Division of Geological Survey Horace R. Collins Laboratory is a multiuse facility located at Alum Creek State Park in Delaware County, Ohio. Core, sample, and twelve other collections are housed at the Ohio Geological Sample Repository. One wing of the facility has laboratories for core and sample description and analysis, petrographic studies, aggregate testing, and sedimentation research. A second wing houses Division of Watercraft Central District offices. The Collins Lab also headquarters the Ohio Seismic Network.

Dedicated October 12, 1999, the Collins Lab provides citizens, industry personnel, and researchers a climate-controlled environment conducive for the study of repository holdings. Facilities include:

  • A sample-preparation and analysis laboratory containing examination tables, petrographic and binocular microscopes, and other examination equipment.
  • A core splitter, a drill press with core-plugging bit, and rock saws to permit the sampling of core and cutting samples for thin sections and other laboratory analyses. Collins Lab personnel will conduct sample preparation and core plugging for a nominal fee.
  • High-resolution core photography is also available.
