The Division of Geological Survey sample repository has approximately 4,300 sets of well cuttings, 230,000 feet of core, and other geological samples available for study. Samples may be examined on site by appointment only. Microscopes are available if needed. Sampling and testing of core is permitted under certain circumstances with prior approval. There is a core-use policy in effect. The samples are housed in the Survey's Horace R. Collins Laboratory, located at Alum Creek State Park north of Columbus. The street address is 3307 South Old State Road, Delaware, Ohio, 43015; telephone (740) 548-7348; fax (740) 657-1979.
The Collins Laboratory is a multi-use facility. In addition to the sample repository, the Division of Geological Survey maintains its publications inventory at the Collins Lab. The facility includes a classroom/conference room furnished with audiovisual equipment (see Guidelines for Use). Telephone and computer lines are available by special arrangement. A learning center is being developed which will highlight rock, mineral, and fossil displays, maps and posters on Ohio geology, and Survey activities. The Ohio Earthquake Information Center is located adjacent to the learning center and houses seismometers in the Ohio Seismic Network. This network can detect earthquakes in Ohio and throughout the world. One wing of the building houses Survey laboratories that are being developed for core and well-cuttings preparation, sample examination, petrographic studies, sedimentation research, and aggregate testing. The Division of Watercraft, Central District, shares part of the office wing and has their publications warehouse on site.
The Division of Geological Survey is always interested in adding to our sample collection. Operators are encouraged to donate well samples and cores in order to attain representative statewide sample coverage for the use of all. The Survey will pick up saved samples and cores if we receive notification.
