  Description:
    Abstract: This digital map database was compiled from previously published and unpublished data by the author and USGS colleagues, and from published maps by others, as indicated in figure 3 on the map sheet.  A pamphlet included with the map provides a brief discussion of the geology of the quadrangle, a description of map units, and references cited.
    Purpose: The map in intended to provide (1) regional geologic information at a scale (1:100,000) intermediate between that of the new New Mexico State Geologic Map (scale 1:500,000) and individual 7- and 15-minute geologic quadrangles at 1:24,000 and 1:62,500, respectively, of part of the western part of the Mogollon-Datil volcanic field; and (2) updated, detailed information on the ages, sources, distribution, and correlation of caldera-related ignimbrites (ash-flow tuffs), and associated extrusive and intrusive volcanic rocks in the northwestern part of the Mogollon-Datil volcanic field.  The ignimbrites are mainly outflow from the major Oligocene and Eocene caldera eruptive centers in adjacent areas, but the Tularosa Mountains 30  60 quadrangle also contains numerous eruptive centers of post-caldera age, which are aligned along major structural trnds of basin and range age (~ 201 million years), and constitute a basaltic to silicic, bimodal volcanic assemblage.
    Supplemental_Information:
      The dataset for the Tularosa Mountains quadrangle consists of six coverages:
      >tulgeop
      >tulflt
      >tulgline
      >tulgpnt
      >tuldpnt
      >tullndec

      The coverage tullndec is not a "true" ARC/INFO coverage.  It consists of various symbols drawn as arcs.

      Also included are the following files, which are used to run the Plot AML in ArcInfo:

      tulplot.aml -- ArcInfo aml used to create a graphics file
      tulplot.gra -- ArcInfo graphics file
      alcgeol.mrk -- ArcInfo marker set
      dike.lin -- ArcInfo line set
      dtpt.mrk -- ArcInfo marker set
      fnt039 -- ArcInfo font used in dtpt.mrk

      Also included is a georeferenced TIFF image (tulrec.tif) derived from a scan of  the Tularosa Mountains quadrangle topographic base map on scale-stable film. The accompanying file called tulrec.tfw is a file generated during rectification of the tiff image in ArcInfo and is needed to use the file tulrec.tif in some applications.

Data_Quality_Information:
  Attribute_Accuracy:
    Attribute_Accuracy_Report: Staff of New Mexico Bureau of Mines and Mineral resources scanned source stable-base material, vectorized scan, attributed files from author drafting and annotations, and produced check plots and coverages. Author and map editor (U.S. Geological Survey) proofread check plots, and digital map specialist reviewed digital files. Digital map specialist and map editor corrected linework and attributing as needed and produced new check plots. Digital map specialist and editor proofread new check plots and reviewed digital files, making final corrections as needed; editor imported files into graphics program to prepare cartographic product.  Author proofread cartographic product (the map sheet layout and pamphlet).  Digital Map Specialist and map editor made final changes to correct attribute errors discovered in the process of cartographic production.  They generated frequency tables to identify errors in attribute spelling and unattributed features.  This map was thoroughly reviewed for conformity with U.S. Geological Survey editorial standards and stratigraphic nomenclature.
  Logical_Consistency_Report: Polygon and node topology are present.  All polygons are labeled and were tested by using the ArcInfo command LABELERRORS.  All polygons were checked for closure, node errors, overshoots, undershoots, dangles, and intersections by using ArcInfo routines.  The ArcInfo commands BUILD and CLEAN were run to ensure the topological consistency of the dataset.
  Completeness_Report: Data are complete.
  Positional_Accuracy:
    Horizontal_Positional_Accuracy:
      Horizontal_Positional_Accuracy_Report: The accuracy of location of polygons, lines, and points is consistent with the map scale of 1:100,000.

      DIPDIRECTION--Refers to direction of dip of bedding surface or foliation, and is given as N (north), NE (northeast), E (east), SE (southeast), S (south), SW (southwest), W (west), or NW (northwest).

      VOLCANICAGE--Refers to the age of the volcanic center or vent in millions of years (Ma), where determined.

      The tuldpnt coverage consists of points that are locations of test wells and road metal quarries.

      The tuldpnt.pat INFO file consists of the following items:

      GEOCODE--Refers to the type of point and is one of the following:  "oil well," "climate well," or "quarry."

      NAME--Gives the full name of the well, either "SWEPI No. 1 oil test well" or "600-m Oberlin University climate test well."
      ----------------------------------------------------------------------
      The tullndec coverage consists of arcs that are line decorations:  bar and ball symbols that show displacement on faults, arrows that show dip direction on faults, and  arrows used to indicate the gradational contact between facies of the upper Pueblo Creek Formation of the Spears Group (annotations:  AF, alluvial facies; VF, vent facies).

      The tullndec.aat INFO file consists of the following items:

      DIPVALUE--Refers to amount of dip on fault, in degrees, where known; a value of 0 was arbitrarily entered in this field for faults where no dip was determined or known.

      DIPDIRECTION--Refers to direction of dip of a fault, and is given as N (north), NE (northeast), E (east), SE (southeast), S (south), SW (southwest), W (west), or NW (northwest).
