Abstract:
The Ute Mountain 7.5' quadrangle is located in the south-central part of
the San Luis Basin of northern New Mexico, in the Rio Grande del Norte
National Monument, and contains deposits that record volcanic,
tectonic, and associated alluvial and colluvial processes over the past
four million years. Ute Mountain has the distinction of being one of the
largest intermediate composition eruptive centers of the Taos Plateau, a
largely volcanic tableland occupying the southern portion of the San Luis
Basin. Ute Mountain rises to an elevation in excess of 3,000 m, nearly
700 m above the basaltic plateau at its base, and is characterized by three
distinct phases of Pliocene eruptive activity recorded in the stratigraphy
exposed on the flanks of the mountain and in the Rio Grande gorge.
Unconformably overlain by largely flat-lying lava flows of Servilleta Basalt,
the area surrounding Ute Mountain records a westward thickening of basin-fill
volcanic deposits interstratified in the subsurface with Pliocene basin-fill
sedimentary deposits derived from older Tertiary and Precambrian sources to
the east. Superimposed on this volcanic stratigraphy are alluvial and
colluvial deposits derived from the flanks of Ute Mountain and more distally-
derived alluvium from the uplifted Sangre de Cristo Mountains to the east
that record a complex temporal and stratigraphic succession of Quaternary
basin deposition and erosion.
Pliocene and younger basin deposition was accommodated along predominantly
north-trending fault-bounded grabens. These poorly exposed fault
scarps cutting lava flows of Ute Mountain volcano. The Servilleta Basalt and
younger surficial deposits record largely down-to-east basinward displacement.
Faults are identified with varying confidence levels in the map area.
Recognizing and mapping faults developed near the surface in young, brittle
volcanic rocks is difficult because: (1) they tend to form fractured zones
tens of meters wide rather than discrete fault planes, (2) the relative youth
of the deposits has resulted in only modest displacements on most faults, and
(3) some of the faults may have significant strike-slip components that do not
result in large vertical offsets that are readily apparent in offset of
sub-horizontal contacts. Those faults characterized as “certain” either have
distinct offset of map units or had slip planes that were directly observed
in the field. Lineaments defined from magnetic anomalies form an additional
constraint on potential fault locations and are indicated as such on the map sheet.
Purpose:
To provide a geologic map database of the quadrangle that
improves understanding of the volcanic events surrounding
development of Ute Mountain and Quaternary surficial deposition
of basin deposits.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Attributes were checked by manually comparing hard copy plots of
the digital data with source materials. Authors and USGS map
editors performed separate reviews.
Logical_Consistency_Report:
Map elements were checked by the authors for overshoots,
undershoots, duplicate features, and other errors. There is a
static topological relationship between the utegeolines and
polygon feature classes. Features were not duplicated, but
coincident lines exist between data layers where appropriate.
Completeness_Report:
Geologic map units were collected and digitized at appropriate
resolution for portrayel on a base at 1:24:000-scale. Data are
complete: no features were eliminated or generalized.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Potential exists for errors in location by the geologist in
the field but many locations of many contacts were aided at
control sites by use of a global positioning receiver with
typical horizontal accuracies less than 20 meters.

Overview_Description:
Entity_and_Attribute_Overview:
The data were created in ArcGIS in Geodatabase format.
The feature dataset representing the geology contains 5
feature clases. A static topologic relationships is established
between ute_geolines, ute_labels, and ute_polygons. The
following description explains the user defined features
within each feature class. Feature classes are as follows:
ute_geolines: contacts, faults, dikes and other boundaries
used to create topologic boundaries of polygons;
ute_labels: label points indicating geologic unit;
ute_polygons: areas representing distribution of geologic
unit;
ute_aeromag: aeromagnetic lineaments interpreted from
reduced to pole aeromagnetic data;
ute_samples: sample point locations for samples used
in the tables for geochemistry and geochronology.
