Description:
Abstract:
The bedrock geology of the 7.5- by 15-minute Hartland and North Hartland, VT-NH quadrangles consists of deformed Ordovician to Cretaceous crystalline metamorphic and intrusive igneous rocks. The database includes contacts of bedrock geologic units, faults, outcrops, structural geologic information, and photographs.
Purpose:
The bedrock geology was mapped to study the tectonic history of the area and to provide a framework for hydrogeologic characterization of the fractured bedrock of Vermont and New Hampshire. The digital data are intended for use by all government, academic, commercial, or other agencies in need of digital geologic map information. The report contains a GIS database, two large-format color sheets in Adobe Portable Document Format (PDF), metadata, and a readme.txt file.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
All attributes digitized during the creation process were verified by displaying the lines and points in the database with respect to the USGS 7.5-minute topographic base map (1:24,000 scale), but no formal tests were performed.
Logical_Consistency_Report:
These data are believed to be logically consistent, though no tests were performed. Geometry is topologically clean.
Completeness_Report:
The geologic contacts were delineated on a USGS 7.5-minute topographic map based on observations at the outcrops shown in the database. Not all outcrops within the area were identified or visited during mapping. The geologic contacts might change if additional outcrops are discovered or exposed as the natural land changes or as the result of development. The features in the database are not based on legal parcels or definitions.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The data were created on a USGS 7.5-minute topographic map at 1:24,000 scale. Therefore, the horizontal accuracy is assumed to be within National Map Accuracy Standards, with a horizontal accuracy of 45.6 feet at the 95% confidence level. Locational information in the field was provided by a Garmin eTrex Venture GPS receiver.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
The data were delineated on a USGS 7.5-minute topographic map at 1:24,000 scale. Therefore, the vertical accuracy is assumed to be within National Map Accuracy Standards, with a vertical accuracy of 11.9 feet at the 95% confidence level.

Process_Step:
Process_Description:
Geology mapped by Walsh in 1995-1996 in Vermont and 2010-2012 in New Hampshire; assisted by Bart T. Cubrich. A preliminary version of the geology of the Hartland quadrangle was published by Walsh (1998). This report supersedes the report by Walsh (1998). This report also supersedes the mapping by Lyons (1955) in the southern half of the Hanover 15-minute quadrangle. The bedrock geology was mapped using standard techniques. Location information during modern mapping (2010-2012) was collected with a GPS receiver (GPS model: Garmin eTrex Venture). Locational data for data mapped in 1995-1996 was obtained by pace, compass, and altimeter and digitized by Walsh. The line and polygon data were compiled in Adobe Illustrator over the topographic basemap. Field and compilation sheets were scanned and registered in Illustrator. Topographic basemap separates were scanned at 400 dpi. Line and polygon data were exported from Illustrator in DXF format to Arc/Info version 10.0. Point data collected in 2010-2012 were collected with GPS imported to ArcGIS version 10.0 to create shapefiles. Point attribute data were entered in an Excel spreadsheet and joined to the GPS data in ArcGIS. Strike and dip data from Walsh (1998) were heads-up digitized in Arc/Info Workstation. The GPS data were collected in latitude and longitude in degrees minutes and seconds in WGS84 datum. GPS data were projected to the New Hampshire Stateplane coordinate system (FIPS Zone 2800) in NAD83 datum, with units in feet. GPS locations were compared to the topographic basemap of the area and repositioned to match the base. The original coordinates remain in the OrientationPoints Feature Class. After editing in Arc/Info, all arcs, polygons, and points were converted to shapefiles. Data in the Vermont State Plane coordinate system were re-projected to the New Hampshire State Plane coordinate system. Line and polygon data were edited in Arc/Info and converted to shapefiles. Shapefiles were plotted in ArcMap and exported to Illustrator. Final cartography was done in Adobe Illustrator. Shapefiles were converted to Feature Classes in an ESRI ArcGIS geodatabase. Meghan E. Mason assisted with geodatabase conversion.
