The geology was mapped from 1997 to 1999 and modified in 2004 to 2008. The geologic mapping was conducted in support of the USGS Rio Grande Basins Project, funded by the USGS National Cooperative Geologic Mapping Program. The mapped distribution of units is based primarily on interpretation of 1:16,000-scale, color aerial photographs taken in 1992, and 1:40,000-scale, black-and-white, aerial photographs taken in 1996. Most of the contacts on the map were transferred from the aerial photographs using a photogrammetric stereoplotter and subsequently field checked for accuracy and revised based on field determination of allostratigraphic and lithostratigraphic units. Determination of lithostratigraphic units in volcanic deposits was aided by geochemical data, 40Ar/39Ar geochronology, aeromagnetic and paleomagnetic data. Supplemental revision of mapped contacts was based on interpretation of USGS 1-meter orthoimagery. This version of the Montoso Peak quadrangle geologic map uses a traditional topographic base from the United States Geological Survey (USGS) overlain on a screened shaded relief base generated from 10-m digital elevation model (DEM) data in the USGS National Elevation Dataset; sun illumination is from the northwest at 45° above the horizon. 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 youth of the deposits has allowed only modest displacements to accumulate for most faults, and (3) many 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. Faults classed as "inferred" were traced based on linear alignments of geologic, topographic and aerial photo features such as vents, lava flow edges, and drainages inferred to preferentially develop on fractured rock. Lineaments defined from magnetic anomalies form an additional constraint on potential fault locations. Purpose: To provide a digital geologic map database of the quadrangle incorporating new constraints on the regional geologic framework.

Native_Data_Set_Environment: Windows_NT, 5.1, Intel ARC/INFO version 9.3 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 visually checked by the authors for overshoots, undershoots, duplicate features, and other errors. There is a static topological relationship between the 'Contacts', 'Unit_label' 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.

Feature classes include 'Contacts', 'Dike', 'Flow_Directions', 'Lineament', 'Polygon', 'Samples', 'Strike_Dip', 'Unit_label', and 'Well_location'. 'Polygon' feature class is contructed using Contacts and 'Unit_ label' feature classes in ArcCatalog. 'Flow_Directions' indicate inferred lava flow directions; 'Dikes' are intrusive dikes; 'Lineaments' are identified on aerial photographs and aeromagnetic data and often are coincident with fracture zones; 'Samples' is a subset of samples listed in Table 2 and 3 and are restricted based on location within the quadrangle. Locations may not be exactly coincident with coordinates in Table 3 because Table 3 coordinates are GPS coordinates whereas sample locations in 'Samples' may be moved based on cartographic requirements. Locations may not be precisely coincident with coordinates in Table 3 Table 3 coordinates reflect GPS coordinates obtained when samples were collected in the field. Map coordinates for some sample points have been adjusted slight for clarity of base cartographic materials but do not reflect significant change relative to actual sampled locations. 'Strike_Dip' are point data representing bedding attitudes; 'Well_location' is the location of well corresponding to the column in Figure 3. Raster datasets include MontosoBasemap.tif/.tfw and MontosoHillshade.tif/.tfw >---------------------------------------------------------------- >Database structure of 'Polygons': >---------------------------------------------------------------- >Field Name Data Type >OID Object ID >Shape Geometry > >Geometry Type-Polygon >UNIT Text > >Length-50 >DESCRIPTION Text > >Length-200 >Shape_Length Double >Shape_Area Double > > >Descriptions of user-defined database items in 'Polygons': >UNIT: Abbreviated name of map unit >DESCRIPTION: Name of map unit and geologic age > >Unique item list for 'Polygons': >UNIT DESCRIPTION >af Artificial fill (latest Holocene) >Qg Gravelly alluvium (Holocene? and late Pleistocene) >Qsw Sheetwash deposits (Holocene to middle?
