The U.S. Geological Survey (USGS), in cooperation with the Arkansas Geological Survey (AGS), has gathered available geophysical logs and related data from the USGS office archives in Arkansas and Tennessee as a basis for developing a hydrogeologic framework for the Southeast region of the United States. Similar efforts were undertaken by the Mississippi Embayment Regional Aquifer Study (MERAS) and the Regional Aquifer-System Analysis (RASA) Program. The logs compiled for these older efforts were difficult to access from the paper files; however, and partly because of this, older and newer logs were compiled into a single digital database for the current study.

This collection consists of processed rock samples as well as unprocessed geological hand samples associated with the research of USGS scientist Robert E. Zartman. Zartman was an early contributor to USGS geochemistry and geochronology research and many of these samples are likely associated with his lab work with K-Ar, Rb-Sr, Sm-Nd, fission track, and U-Th-Pb dating methods. This collection contains one pallet of geological samples and one pallet of laboratory equipment.
