Geologically, the area lies on the southern flank of the Ozark dome, an uplift that exposes oldest rocks at its center in Missouri. Physiographically, the Boxley quadrangle lies within the Boston Mountains, a high plateau region underlain by Pennsylvanian sandstones and shales (Purdue and Miser, 1916). Valleys of the Buffalo River and its tributaries expose an approximately 1,600-ft-(490-m-)thick sequence of Ordovician, Mississippian, and Pennsylvanian carbonate and clastic sedimentary rocks (fig. 2) that have been mildly deformed by a series of faults and folds. Part of Buffalo National River, a park encompassing the Buffalo River and adjacent land that is administered by the National Park Service, extends through the eastern part of the quadrangle. Mapping for this study was conducted by field inspection of numerous sites and was compiled as a 1:24,000-scale geographic information system (GIS) database. Locations and elevation sites were determined with the aid of a global positioning satellite receiver and a hand-held barometric altimeter that was frequently recalibrated at points of known elevation. Hill-shade-relief and slope maps derived from a U.S. Geological Survey 10-m digital elevation model as well as orthophotos were used to help trace ledge-forming units between field traverses within the Upper Mississippian and Pennsylvanian part of the stratigraphic sequence. Strike and dip of beds were typically measured along stream drainages or at well-exposed ledges. Beds dipping less than 2° are shown as horizontal. Structure contours, constructed on the top of the Boone Formation and the base of a prominent sandstone unit within the Bloyd Formation, were hand drawn based on elevations of control points as well as other limiting information on their maximum or minimum elevations. Purpose: To provide a digital geologic map database of the quadrangle that improves understanding of the regional geologic framework and its influence on the regional ground water flow system.

Native_Data_Set_Environment: ArcInfo version 9.1 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 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 Polygon, contacts, Boundary, faults, and labelpoints 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 portrayal on a base at 1:24000 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 m. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Contact locations were also aided by use of a barometric altimeter with vertical resolution of about 6 m tied to topographic contours with vertical accuracy of about 6 m. Topographic basemap elevations values (boxleybase.tif) are from the published USGS 7.5-minute topographic map. Hill- shade-relief, slope analysis, and slope of the slope analysis raster datasets were computed from the U.S.G.S digital elevation models with a vertical accuracy of 10 feet or less. Lineage: Process_Step: Process_Description: Original mapping of geology was completed. Process_Date: 2005 Process_Step: Process_Description: The original map data were imported into ArcMap/ArcInfo as point data.

The 'Polygons' features class contains geologic polygons constructed using the 'contacts', 'Boundary' and 'faults' feature classes as the bounding arcs and 'labelpoints' to attribute the polygons. Other structural features are in 'folds'. Attitudes for bedding are included in 'attitudes_flat' and 'attitudes_inclined'. Structural contours interpreted for the upper contact of the main body of the Boone Formation are in 'strcnt_Mb' and structural contours for the base of the upper Bloyd Formation are in 'strcnt_Pbu'. Field locations the structural countours are constructed from are in 'cntrlpts_Mb' and 'cntrlpts_Pbu', respectively. Cross-section lines for A-A' and B-B' are in 'crosssection'. >----------------------------------------------------------------- >Database structure of 'Polygons':
