The DCL is currently producing maps in the new DGM series as part of the State Map Program. Multiple coverage of varied scales and vintages is common in the San Juan Basin. Any donation of vintage photographs will be accepted and catalogued. Reasonable purchase agreements for photos of areas where our collection is sparse will be considered. The purpose of the Core Library is to have available for study representative cores from rock formations in different parts of New Mexico.
Microscopes are available for visitors' use.
There are several types of splitting machines in the Core Library. However, all sampling must be approved before samples are taken. In addition to the cores, location information, geophysical logs, driller's logs, and other materials are available for many holes. More than 1000 different cores donated by 156 companies or other organizations are ready for examination and many others are being processed. The age of units in these cores ranges from Precambrian to Holocene.
