In 1990,the U.
S. Geological Survey, in cooperation with the U.
S. Department of Energy Idaho Operations Office, and established the Lithologic Core Storage Library at the Idaho National Laboratory (INL). The facility was established to consolidate,catalog, and permanently store nonradioactive drill cores and cuttings from subsurface investigations conducted at the INL, or to provide a location for researchers to examine,sample, and test these materials.
The facility is open by appointment to researchers for examination, or sampling,and testing of cores and cuttings. This report describes the facility and cores and cuttings stored at the facility. Descriptions of cores and cuttings include the corehole names, corehole locations, and depth intervals available.
Most cores and cuttings stored at the facility were drilled at or near the INL,on the eastern Snake River Plain; however, two cores drilled on the western Snake River Plain are stored for comparative studies. Basalt, and rhyolite,sedimentary interbeds, and surficial sediments compose most cores and cuttings, and most of which are continual from land surface to their total depth. The deepest continuously drilled core stored at the facility was drilled to 5000 feet below land surface. This report describes procedures and researchers' responsibilities for access to the facility and for examination,sampling, and return of materials.
