Geologic map of the Santa Ana Pueblo quadrangle, Sandoval County, New Mexico

The Santa Ana Pueblo quadrangle is located in the northern part
of the Albuquerque basin, which is the largest basin or graben
within the Rio Grande rift. The quadrangle is underlain by
poorly consolidated sedimentary rocks of the Santa Fe Group and
is dominated by Santa Ana Mesa, a volcanic tableland underlain
by basalt flows of the San Felipe volcanic field. The San
Felipe volcanic field is the largest area of basaltic lavas
exposed in the Albuquerque basin. The structural fabric of the
quadrangle is dominated by dozens of generally north striking,
east- and west-dipping normal faults associated with the
Neogene Rio Grande rift.
