Compilation of the digital database depended on advice and assistance in the use of ALACARTE - ARC/INFO from T.T. Fitzgibbon, C.M. Wentworth, and G.A. Phelps, and Johanna Fenton
Together with the description of map units (btyrep.txt or btyrep.ps), and in conjunction with the recently published Nevada Test Site Region map database (Sawyer and others, 1995, USGS Open-File Report-567), the Beatty geologic map database provides the most recent synthesis of the stratigraphy and structural geology of the southwestern Nevada volcanic field, the Nevada Test Site, and the Yucca Mountain site.
