H. R. Collins Laboratory
& Geological Sample Repository
Core Sample Use Policy
The ODNR Division of Geological Survey desires to make its core samples readily accessible for legitimate and professional scientific research by qualified practicing geologists, trained geotechnical individuals, consulting firms, graduate geology students, and university geology faculty. At the same time, the Division of Geological Survey has a determined responsibility to permanently preserve a minimum of one half (½) of the original diameter for each core held at the Sample Repository. In order to achieve a balance of these goals, the following Core-Use Policy and the Permission Form for use by non-ODNR personnel have been prepared. Please note: there is a separate Oil-and-Gas Well Cuttings Use Policy.
The H. R. Collins Laboratory (HRCL) is available for use by appointment only and during normal business hours (8:00 a.m. to 4:30 p.m., M–F, excluding state holidays). Access is given on a first-come first-served basis unless special permission is given by the Division Chief. All non-ODNR personnel should review this core sample use policy and complete the Permission Form for use of laboratory facilities and core/sample repository. To schedule a visit, please send a brief e-mail to firstname.lastname@example.org describing the project, cores to be examined, duration of study, anticipated reports or publications, mailing and e-mailing addresses, and telephone numbers (including cell phone numbers) of each investigator. Completed permission forms should be submitted to the Facility Coordinator, Aaron Evelsizor, prior to or during the scheduled visit.
Written requests to examine or borrow core samples should be submitted to:
ODNR Division of Geological Survey
H. R. Collins Laboratory
3307 South Old State Road
Delaware, OH 43015-7635
The Division of Geological Survey greatly prefers and highly recommends that core be examined at the HRCL. When macroscopic sample examination is not sufficient, a few thin-section billets may be provided as long as the minimum ½ core is preserved. If (1) many samples are requested, (2) destructive testing is involved, or (3) the core is to be examined off-site, a formal request must be submitted. The following requirements also apply:
- The request must be specific as to which cores are required and the amount of sampling necessary. Sampling of cores must be kept to the minimum (i.e., generally not more than a quarter (1/4) core for cores 2 inches or less in diameter nor more than an eighth (1/8) core for cores greater than 2 inches in diameter).
- All borrowers are subject to the Compensation in Appreciation of Services schedule; all costs related to sampling, handling, or transporting core material shall be borne by the borrower. If cores are to be split, this will be done at the HRCL unless other arrangements are approved by the Facility Coordinator.
- Cores remain the property of the Division of Geological Survey. Thin sections, polished sections, sample residues, etc. made from sampled portions of the cores shall be returned at the conclusion of the project to become part of the Division of Geological Survey's permanent library for the benefit of the public. All thin sections, billets, and sample residues should be clearly labeled with core number and footage.
- Each core generally shall be on loan for a period of no longer than 45 business days. Under certain circumstances, a limited extension to the original loan may be granted. A formal, written request must be submitted two weeks prior to the expiration of the original loan and can be submitted as an e-mail attachment. In the event returned core is determined to have been damaged, improperly handled or sampled, or is otherwise in poor condition, the borrower will forfeit the privilege of borrowing other materials from the core repository.
- Final sampling arrangements shall be set forth in an e-mail from the Facility Coordinator and acknowledged by the borrower.
- Copies of core sample descriptions, data, analytical results, unpublished and published reports, must be supplied to the Division of Geological Survey. All data should be made public through independent publication and/or placed on open file at the Division of Geological Survey. In certain very unusual circumstances, information may be placed in a confidential status under the authority of the Division Chief (ORC §1505.03).
- The Division of Geological Survey must be properly acknowledged in any unpublished report or formal publication resulting from the inspection and/or analysis of samples it holds.
