Also, any core removed for sampling must be replaced with a marker showing the name of the sampler, organization, date, and footage of core removed. The State Geologist must approve sampling of the cores and samples for thin section or destructive purposes. Thin sections or other data must be returned to the library upon completion of the study or upon request. The Survey is to receive a copy of all research results, data, reports, publications, interpretations, assays, and logs form the examination of the core. This information will become part of the public record.
Some core holes have lithologic logs which have been placed on open file.
However, there may be some core holes along with lithologic logs which are held confidentially. It may be possible to view the cores and obtain confidential lithologic logs by contacting the company that provided the core and logs. It is the responsibility of the user to obtain written permission to view the core and have the lithologic logs released. University students borrowing core and samples for use in reports, research or thesis, sign a special use agreement form. They must have their major professors take full responsibility, in writing, to see that all materials are returned in good condition and all necessary reports, research, etc., are submitted to the Survey in a timely manner.
