The Nevada Bureau of Mines and Geology (NBMG) Sample Collection Database (also known as CORECUT) is the index of rock samples held by the NBMG. The database contains about 12,000 entries of which over 11,000 entries have locations in longitude and latitude (the on-line database includes only these). Access is through the NBMG main website at http://www.nbmg.unr.edu, followed by clicking on 1). "Collections", and 2). "Geologic Specimen and Geochemical Database". In 2019, NBMG began a project to photograph and scan thin sections under standard and cross polarized light. When applicable, these are now noted in the metadata records. All of the cores and cuttings are now also available in a new map web application http://nbmg.maps.arcgis.com/apps/webappviewer/index.html?id=2b2fc33d346...
