  Description:

    Abstract:
      The Craters of the Moon 30 x 60 minute quadrangle shows the geology of the 
        northern two-thirds of the Craters of the Moon (COM) lava field and 
        volcanic structures of the northern and central parts of the Great Rift 
        volcanic rift zone.  The COM lava field is the largest, predominantly 
        Holocene lava field in the conterminous United States.  The northwest 
        corner of the map shows older sedimentary, intrusive, and volcanic rocks 
        that range in age from Ordovician to Miocene.  These rocks provide 
        evidence of compressional fold and thrust events of the Antler and 
        Sevier orogenies.  Compression was followed by voluminous volcanism 
        represented by the Challis Volcanic Group.  Basin-and-Range faulting 
        followed in Neogene time.
      The COM lava field covers about 1,600 square kilometers and contains about 
        30 cubic kilometers of lava flows and associated vent deposits.  
        Stratigraphic relationships, paleomagnetic studies, and radiocarbon ages 
        indicate that the field formed during eight eruptive periods designated 
        as H, the oldest, to A, the youngest.  Each eruptive period was several 
        hundred years or less in duration and separated from other eruptive 
        periods by non-eruptive recurrence intervals of several hundred to about 
        3,000 years.  The first eruptive period began about 15,000 carbon-14 
        years ago and the latest one ended about 2,100 carbon-14 years ago.
      All available field, paleomagnetic, radiocarbon, and argon-40/argon-39 
        data are incorporated in this map and they quantitatively refine the 
        volcanic and paleomagnetic history of the pre-Holocene lava fields and 
        the COM lava field.  In a sense, these data determine the "pulse rate" 
        for Pleistocene and Holocene basaltic volcanism in the area of this map.
      Twenty-three new argon-40/argon-39 geochronologic data reveal a fairly 
        complete and continuous record of basaltic volcanism in the Craters of 
        the Moon 30 x 60 minute quadrangle for the last 500 ka.  The ages 
        cluster into age groupings at ~30 ka, 50-70 ka, 100-125 ka, 260-290 ka, 
        320-340 ka, and 475 ka.  There are apparent periods of ~30 to 60 ka 
        duration when little or no volcanic activity took place between groups.
      Magnetic polarity and remanent inclination and declination directions for 
        most lava flows in the quadrangle have normal magnetic polarity; they 
        were emplaced during the Brunhes Normal Polarity Chron and are younger 
        than 780,000 years.  Directions of remanent magnetization and the new 
        argon-40/argon-39 ages were used to correlate and approximately date 
        lava flows and lava fields for this map.
    Purpose: 
      This map provides geologic, geochronologic, paleomagnetic, and 
        petrographic data for the northern part of the predominantly Holocene 
        Craters of the Moon lava field, for late Pleistocene lava fields 
        surrounding the Craters of the Moon field, and for sedimentary and 
        volcanic rocks in the southern part of the Pioneer Mountains.  These 
        data will contribute to wise management and preservation of the Craters 
        of the Moon National Monument and for broad-scale understanding of the 
        basaltic-volcanic evolution of the eastern Snake River Plain.

Data_Quality_Information:

  Attribute_Accuracy:
    Attribute_Accuracy_Report:
      Attributes were checked by manually comparing hard copy plots of the 
      digital data with the source materials.  Authors and USGS map editor 
      performed separate reviews.

  Logical_Consistency_Report:
    Map elements were visually checked for overshoots, undershoots, duplicate 
      features, polygon closure, and other errors by the author and by the GIS 
      technician(s) that created the digital database.  Automated (ArcInfo) 
      routines were also used to check the databases for polygon label errors, 
      line or point attribution errors, sliver polygons, dangling arcs, 
      intersection errors, and projection information.  Check plots of the map 
      were reviewed by at least two other geologists for consistency with basic 
      geologic principles and general conformity to USGS mapping standards.
