This report is a brief compilation of the general geologic history of the Mesa 10 x 20 NTMS quadrangle of east-central Arizona (33 - 340 N. latitude, 110-1120 W. longitude). References listed at the end of the report are divided into a general geology section, an MS and PhD thesis section, listing only works of broad scope or interest, and a section at the end dealing with uranium occurrences. This report accompanies a 1:250,000 map of the general geology of the quadrangle which has an accompanying legend. A separate map shows known mineral occurrences in the quadrangle. Eight regional cross sections oriented NE-SW and extending through the Mesa quad are included with the map.
