The CRC includes modern core and cutting examination rooms, microscopes, and sampling and photography equipment. For each NPRA core, the USGS Core Research Center maintains two formats. A slabbed face of each core represents the archive format and the butt of each core represents the sample format. The archive format is used for examination, photography, and spotting samples. Once participants spot sample locations, the CRC staff collects samples from corresponding locations in the sample format.
Additional information regarding sampling policy is available at the CRC web site .
Accommodations are the responsibility of individual workshop participants.
