Field mapping and stereonet analysis of brittle and ductile structural data collected during 1:24,000-scale geologic mapping of the Milford quadrangle yielded the following general observations, which suggest that the ductile deformational history of this region appears to have strongly influenced the later development of brittle structures in the same rocks: The behavior of these fractures in relation to ductile structure have implications for rheological constraints on tectonic models of the post-Alleghenian core of the New England Appalachians, hydrogeologic models of regional fractured bedrock aquifers, and the interpretation of topographic lineaments. %B Geological Society of America Abstracts with Programs %7 2 %I Geological Society of America (GSA) : Boulder, CO, United States %C Buffalo, NY %V 40 %P 3 %8 03/2008 %G eng %U https://gsa.confex.com/gsa/2008NE/finalprogram/abstract_134899.htm %0 Online Database %D 2004 %T Well inventory of the Marlborough quadrangle, Massachusetts %A Duncan, C. %A Stephen B Mabee %K #MGSPub %K #Subsurface %K #WellInventory %K Ashland %K Berlin %K boring %K Hopkinton %K Hudson %K Malborough %K Marlborough %K Northborough %K Southborough %K subsurface %K Upton %K water resources %K wells %K Westborough %X

Well Inventories consist of ESRI ArcView Project files (*.apr), associated ESRI shapefiles and scanned boring logs compiled from several sources.   Each *. apr file displays borehole locations, information about the boring itself, and, where available, a scanned image of the boring log.  Be sure to read the "README.TXT" file before using this product.
