The John C. Green Collection (Green collection) contains approximately 365 thin section slides, 17 original field notebooks, published and unpublished maps, over 1000 index cards of petrographical and mineralogical information, as well as georeferenced maps and point data in GIS geodatabase format. The data was collected by Dr. John C. Green between 1956 and 1963 in preparation for his PhD dissertation, The geology of the Errol quadrangle, New Hampshire-Maine (Green, 1960) at Harvard University and the subsequent Geological Society of America Special Paper, Stratigraphy, and structure of the Boundary Mountain anticlinorium in the Errol quadrangle, New Hampshire-Maine (Green, 1964). Of the roughly 365 thin sections,...
This collection contains 15 1:24,000-scale surficial geologic maps throughout NH in Geologic Map Schema (GeMS) format. Specific 7.5-minute quadrangles include Bartlett, Bradford, Center Sandwich, Danbury, Hillsboro Upper Village, Jackson, Jefferson, Lancaster, Melvin Village, Mount Grace, Mount Chocorua, Mount Dartmouth, New London, Royalston, and Squam Mountains. The data preservation work in this project involved converting legacy geologic map schemas to full GeMS compliance. This dataset includes GIS surficial data for each quadrangle in the following formats: Esri geodatabase, shapefile, text, Microsoft Excel, and xml. The deliverables also include a PDF of the geologic map showing surficial geology, description...
