Geologically, the region lies on the southern flank of the Ozark dome, an uplift that exposes oldest rocks at its center in Missouri. Physiographically, the map area spans the Springfield Plateau, a topographic surface generally held up by Mississippian cherty limestone and the higher Boston Mountains plateau to the south, held up by Pennsylvanian rocks. The Buffalo River flows eastward through the map area, enhancing bedrock erosion of an approximately 1,600-ft- (490-m-) thick sequence of Ordovician, Mississippian, and Pennsylvanian carbonate and clastic sedimentary rocks that have been mildly deformed by a series of faults and folds. Quaternary surficial units are present as alluvial deposits along major streams, including a series of terrace deposits from the Buffalo River, as well as colluvium and landslide deposits mantling bedrock on hillslopes. Purpose: To provide a geologic map database of the map area that improves understanding of the regional geologic framework and its influence on the regional groundwater flow system. Furthermore, additional edits were made to the Ponca and Jasper quadrangles in the following ways: new control points on important contacts were obtained using modern GPS; recent higher resolution elevation data allowed further control on placement of contacts; some new contacts were added, in particular the contact separating the upper and lower Everton Formation.

Native_Data_Set_Environment: ARC/INFO version 10 Browse_Graphic: Browse_Graphic_File_Name: http://pubs.usgs.gov/sim/3314/ Browse_Graphic_File_Description: Graphical representation of the map Browse_Graphic_File_Type: pdf 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 such as overshoots, undershoots, duplicate features, and other errors were identified through standard topological checks within ArcGIS and by visual inspection. There is a static topological relationship between the polygon, geology_arc, and geology_label feature classes. 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. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Contact locations were also aided by use of a barometric altimeter with vertical resolution of about 6 meters tied to topographic contours with vertical accuracy of about 6 meters. Topographic basemap elevation values are from published USGS 7.5-minute topographic maps. Hillshade raster was created from USGS NED 10 meter digital elevation model data, available for download from http://nationalmap.gov.
