Generalized lithology for lithogeochemical classification of the bedrock of Vermont

This data release provides a generalized lithology look-up table for the lithogeochemical classification of Vermont's bedrock geologic map units. The table is defined from the mapped bedrock geologic units published by Ratcliffe and others (2011) and the generalized lithology of rock group A and rock group B for lithogeochemical classification as defined by Robinson and Kapo (2003). The 2003 classification was created for all six New England states and Vermont's geologic units were based on an older, less detailed, bedrock map of Vermont by Doll and others (1961). The new data table in this data release is designed to be joined with the published attribute table from the 2011 map database, as part of the bedrock geologic map unit polygons. The join attribute is the item called "Lith" in the 2011 map database. The data table is non-interpretive and the 2011 map data were not modified. The data release contains two files, including one metadata file and one comma-delimited (CSV) file: VTcontax_attrib_lithology.csv.
