The Newton quadrangle, located west of Boston, Massachusetts, is mainly underlain by clastic sedimentary and minor igneous rocks occupying the topographic Boston Basin (Crosby, 1880; Emerson, 1917; LaForge, 1932; Billings, 1976 and references therein). Fault blocks dominated by older plutonic and volcanic rocks truncate the Basin sequence on the west and south. Although fossiliferous Cambrian strata overlying plutonic basement had been reported some 30 miles away in North Attleboro, MA (Billings, 1929), the first quadrangle map including the Newton area (1:62,500 Plate I of LaForge, 1932) portrayed the plutonic units as {\textquotedblleft}Early Paleozoic{\textquotedblright} and assigned all the others to the Devonian or Carboniferous periods. By the time the Newton quadrangle appeared at 1:24,000 scale (Kaye, 1980), emerging U-Pb zircon geochronology had revealed Neoproterozoic (Ediacaran in timescale of Gradstein et al., 2012) crystallization ages both for the Mattapan Volcanic Complex and the Dedham Granite on the south side of the map area (Kaye and Zartman, 1980; written communication of Zartman and Naylor, 1980 not published until 1984). The Boston Basin sequence in this map was inferred to be Neoproterozoic in the absence of a break with overlying Cambrian strata (Kaye and Zartman, 1980), an interpretation confirmed shortly thereafter by the discovery of Ediacaran microfossils in the top portion of the sedimentary section ({\textquotedblleft}Vendian{\textquotedblright} in Lenk et al., 1982). In the map presented here, U-Pb zircon dates obtained by the author over twenty years with colleagues at MIT{\textquoteright}s Radiogenic Isotope Lab constrain all map units except mafic dikes. During this interval, U-Pb analyses have become more precise and accurate, leading also to significant refinements to the dates used by Kaye in 1980, as discussed further in the section on Stratigraphy.\

This map shows the stacked vertical distribution of nonlithified surficial earth materials within the Marlborough quadrangle. This series of maps shows these deposits as they are vertically arranged in units from bottom to top. Surficial materials include mineral and rock particles in glacial deposits, and mineral, rock, and organic particles in postglacial deposits. Surficial materials also are known in engineering classifications as unconsolidated soils, which include coarse grained soils, fine grained soils, or organic fine grained soils. Surficial materials underlie and are the parent materials of modem pedogenic soils which have developed in them at the land surface. Delineation of the materials is based on surficial geologic mapping (Stone, 1978, Hildreth, 2003, 2004), the identification of glacial meltwater morphosequence deposits, knowledge of the deglaciation history of New England, and examination of borehole logs and water well records. For this set of maps, glacial meltwater deposits are distinguished by their geomorphologic expression, sediment type, and depositional environment. These deposits are further subdivided into a series of related glacial sedimentary facies, which are stacked vertically within each glaciaodeltaic or lake-bottom deposit. Postglacial deposits at the land surface are differentiated by their sediment type and geomorphic expression. The principal surficial materials map shows the distribution of these materials exposed at land surface. The smaller inset maps (maps A-F) show the surface and subsurface distribution of the glacial meltwater deposits , including the distribution of specific sedimentary facies that compose these meltwater deposits. By using each inset map in sequence both the lateral extent and vertical arrangement of the deposits at a particular location can be estimated from bottom to top.

This general area comprises the suture between the Gander and Avalon composite terranes of the Northern Appalachians (cf. Hibbard et al., 2006). Metasedimentary rocks of the Merrimack Terrane are generally poorly exposed, with intrusives (Day, Dayp, SDgdt) and the Clinton-Newbury Fault zone and associated rocks (Ot) forming a prominent northeast trending ridge (Oak Hill in the town of Harvard) marking the eastern bordering slope of the Worcester Plateau (Emerson, 1917, p. 16). Elevation and local topographic relief gradually decreases and glacial cover increases to the east-southeast across the strike of the Nashoba Formation, which, locally, forms low-relief NE-trending strike-parallel ridges. These are cut by dramatic cross-strike cliffs and glacial spillway gorges developed along cross-strike joints and brittle faults, most notably on the western slopes of Rattlesnake Hill, southern slope of Powder House Hill and in Camp Resolute in Bolton in the west-central portion of the quadrangle, and the southern slope of the hill along the west side of Codman Hill Road in Harvard in the north-central portion of the quadrangle. The migmatitic ortho- and paragneisses, schists and associated metavolcanic rocks of the Nashoba Formation (_Sn) form a northeast striking belt underlying the southern two-thirds of the quadrangle.

These efforts have been organized nationally through programs such as the U.S. Department of Energy {\textendash} Office of Fossil Energy {\textendash} National Energy Technology Laboratory (NETL) {\textendash} Carbon Sequestration Program and the United States Geological Survey (USGS) {\textendash} Energy Resources Program {\textendash} Health and Environment Section {\textendash} Geologic CO2 Sequestration Research initiative. These organizations have partnered with a network of regional participants to evaluate CO2 storage resource potentials in geologic formations throughout the United States and Canada, through the Regional Carbon Sequestration Partnerships program. To date, however, CO2 storage resource potentials for geologic formations in Massachusetts have not been incorporated into any national or regional carbon sequestration initiative, nor have resources for local geologic carbon storage in Massachusetts been estimated or calculated. During a preliminary investigation into geologic carbon sequestration potential in Massachusetts, researchers at the University of Massachusetts identified five potential candidate geologic formations for further study. These include: sandstone aquifers in the Connecticut River Valley, unmineable coal seams in southeastern Massachusetts, organic-rich shales in the Connecticut River Valley, basalts in the Connecticut River Valley, and organic-rich metamorphic rocks in the western Berkshire Hills. Through sponsorship from the Massachusetts Clean Energy Center, a project was developed to gain more information about these candidate formations related to their hydrogeologic characteristics and potential carbon storage resource. This information has been used to assess if some or all of these candidates meet screening criteria for geologic carbon storage and to provide data for volumetric carbon storage models as outlined by methodologies developed by the USGS and NETL. This research also has identified gaps in knowledge and information regarding key hydrogeologic characteristics for the candidate formations in Massachusetts. These data are required to determine if formations meet screening criteria and to estimate total storage resources.

  • To recreate and validate prior carbonate mineralization experiments conducted on the Holyoke basalt by Schaef et al.

    The University of Massachusetts Department of Geosciences and Office of the Massachusetts State Geologist were asked by the Franklin Regional Council of Governments to make an assessment of the extent, thickness and hydraulic properties of the West Charlemont aquifer located in valley fill deposits along the Deerfield River in the Town of Charlemont, Massachusetts. Previous work by Gay et al. (1974) mapped these fill deposits as a medium yield aquifer (51 gallons per minute, gpm, to 200 gpm). The purpose of this investigation is to evaluate further the potential of this medium yield aquifer as a viable groundwater resource for the Town of Charlemont. Results from six new seismic refraction surveys, three new boreholes, analysis of grain size distribution curves and a review of previous borehole logs and geophysical surveys were compiled to build a conceptual 3-dimensional visualization of the aquifer system. These data were used to make a first-order estimate of potential yield.
