The Narragansett Basin covers a approximately 1500 Km (super 2) area in southern Massachusetts and is dominated by complexly deformed and metamorphosed, Pennsylvanian-aged, fluvial and alluvial deposits. A northeast-striking series of brittle faults and discrete shear zones define the southern margin of the basin. Preliminary modeling of igneous and gneissic fabrics from outcrops along the southern edge of the basin show that the granite dips predominantly north, northeast. This pattern suggests that granitoids along the southern edge of the basin continue beneath the Narragansett Basin and correlate with granitoids exposed to the north. Regional joint sets in the Fall River pluton can be grouped into three dominant clusters at 350 degrees , 90 degrees , and 250 degrees based upon 86 field measurements. Low-angle sheeting joints are also common and suggest interconnected fracture networks at depth. Preliminary geochemistry from the Fall River pluton suggests that feldspars and accessory minerals contain the appropriate concentrations of heat producing elements, primarily U, Th, and K, to be a reasonable geothermal resource. K (sub 2) O values range from 2.4 to 5.0 weight percent. U and Th values (in ppm) range from 0.9 to 6.2 and 2.9 to 30.1 respectively. Assuming a relatively consistent composition at depth, a density of 2.6 kg/m (super 3) , and a thermal conductivity of 2.9 W/m degrees C, initial temperature modeling suggests average temperatures of 81 degrees C at depths of 5 kilometers and 93 degrees C at depths of 6 kilometers. Temperature estimates increase to approximately 150 degrees C and approximately 170 degrees C respectively when a two kilometer thick sediment package is modeled overlying the granitoids. The goal of current and future work is to improve assumptions about compositional uniformity as well as the regional position of granitoids at depth. At the conclusion of this work we hope to develop a protocol for studying geothermal potential of buried granitoids in New England in the absence of reliable drill-hole data. Preliminary estimates from this project suggest that basins underlain by granitoids of compositions similar to that of the Fall River pluton have reasonable potential as a deep geothermal resource.}, keywords = {$\#$StaffPubs, depth, Economic geology, geology of energy sources 29A, Fall River Pluton, geochemistry, geothermal energy, gneisses, granites, Igneous and metamorphic petrology 05A, igneous rocks, intrusions, massachusetts, metamorphic rocks, plutonic rocks, plutons, southeastern Massachusetts, United States}, isbn = {00167592}, url = {https://gsa.confex.com/gsa/2011NE/finalprogram/abstract_185900.htm}, author = {Goodhue, Nathaniel and Koteas, G.

This is the first investigation of CT deep geothermal resources. Many CT granitoids contain heat producing elements. The goal is to identify geologic units capable of producing enough heat, at reasonable drilling depths, to operate a viable geothermal power plant. Target rock units must contain enough uranium, thorium and potassium (U/Th/K) in combination with heat generated through the natural geothermal gradient of the Earth to generate electricity and co-produced direct heating. Heat at depth can be concentrated by an overlying insulating layer of sedimentary rocks and glacial sediments. 27 CT bedrock units were selected for sampling using existing mapping. 120 samples were analyzed using X-Ray Fluorescence Spectrometry. Heat production values (HPVs) at or greater than 4 mu W/m (super 3) were considered to be of interest. Values ranging from 4 to 18 mu W/m (super 3) were calculated for 7 of the 27 rock units. Elevated concentrations of thorium, ranging from 10.5 ppm to 245 ppm, were the primary contributors to increased HPVs. Initial results indicate that the warmest rocks are Permian and Precambrian, which is consistent with earlier results from granitoid bodies underlying the Atlantic Coastal Plain of Virginia (Speer et al., 1979). Additional bedrock samples will be analyzed to further characterize geochemical variations and potential HPVs of target rock units. Direct thermal conductivity measurements are being made of select bedrock samples in addition to sedimentary rocks of the Hartford Basin. Theoretical thermal profiles derived from rock geochemistry will provide an estimate of heat generated at depth for geologic units of interest and assist in determining the potential for an insulating layer overlying heat producing granitoids. Direct thermal conductivity measurements of unconsolidated materials throughout CT are also being made to support the ground-source heat pump industry. All data and mapping will be accessible via the National Geothermal Data System (NGDS).}, keywords = {$\#$StaffPubs, Connecticut, Economic geology, geology of energy sources 29A, energy sources, geothermal energy, geothermal exploration, geothermal gradient, granites, heat flow, igneous rocks, New England, plutonic rocks, temperature, thermal conductivity, United States}, isbn = {00167592}, url = {https://gsa.confex.com/gsa/2012NE/finalprogram/abstract_200494.htm}, author = {Gagnon, Teresa K. and Koteas, G.

On starting the program, the user chooses the media source: either "Web-Access" (from a server) or "Local Access" (from DVD, flash or disk drive) and immediately sees a "Home Screen". The Home Screen displays the location of five detailed maps and buttons linked to Indexes (lists) of DDM content. Each map contains numbered icons that link that location to a field guide of that site. Camera icons on the detailed maps point in the direction photos were taken; many photos are oblique aerials that place the map features in context. The aerials contain camera icons of ground photos along the field trip route. The maps can be toggled between an orthophoto map or a topographic map, each geo-referenced. Key field guide locations have 360-degree QuickTime panoramics. All images and movies have captions. The DDM-SedRxWMa program is made from the DDM-Template and is capable of displaying text (captions or field guides) at 3 different user-selectable levels. The text might instead be displayed in 3 different languages. The DDM-SedRxWMa, which includes a 7 minute automated guided tour, can be downloaded at http://ddm.geo.umass.edu/ddm-sedrxwma/ The DDM-Template is an open source program that anyone can use to make their own DDM. It and a step-by-step manual (the "Cookbook") are available along with over 20 DDMs at http://ddm.geo.umass.edu). Making a DDM from the Template requires the use of the relatively inexpensive and easy to learn, multi-platform programming environment Runtime Revolution (www.runrev.com). Maps and photos (jpeg files) and movies are stored outside the program, which acts as an organizational framework and index to present it. Text and data are saved within the program and can be imported from html, rtf or txt format files. Map unit labels, sample sites, and graphics, such as camera icons (created in the Template) can be overlain on the maps or images; and provide a link to view the associated data or images. Once the Template has been modified and renamed, a single step creates 3 royalty-free, stand-alone programs, one each for Unix, Windows and Macintosh operating systems. A DDM program matching the user{\textquoteright}s operating system can be made available online.}, keywords = {$\#$StaffPubs, cartography, digital cartography, digital data, digital terrain models, education, Environmental geology 22, government agencies, land use, mapping, national parks, public lands, research, U.

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.
