The LG and MG are mineralogically and geochemically granitoidal lineated orthogneisses. They contain deformed mafic xenoliths, as well as aplitic, granitic and pegmatoidal dikes that cut the dominant lineation. Based on chemical analyses, the LG from FRP and the MG plot as granite on the IUGS diagrams and the Le Bas diagram. Similarity in incompatible trace element ratios (e.g., Zr/Nb) and highly evolved characteristics of aplite with respect to the host gneisses, indicate there is probably a genetic link between the MG and the FRP LG. These rocks are chemically distinct from other nearby felsic gneiss. Phenix City gneiss amphibolites from Lindsey Creek and North Highland Mills dam in Columbus were also analyzed for major and trace elements. These amphibolites are low K tholeiitic rocks with an island arc affinity and are similar to rocks from the area that have already been analyzed. The amphibolites show a wide range of fractionation (41 to 62 percent SiO (sub 2) ). Consistency in incompatible element ratios over a wide range of fractionation of some of the samples show a probable genetic relationship among the various amphibolites of Lindsey Creek. Future work should involve more extensive collecting and analysis of both felsic rocks and amphibolites in the Uchee belt. More time should also be spent describing the thin sections of the existing collection and comparing the REE patterns for the FRP, MG and other felsic rocks in the Uchee belt.}, keywords = {$\#$StaffPubs, Alabama, amphibolite, chemical composition, Columbus Georgia, dikes, Georgia, gneisses, Igneous and metamorphic petrology 05A, inclusions, intrusions, metamorphic rocks, Muscogee County Georgia, Uchee Belt, United States, xenoliths}, isbn = {00167592}, author = {Joseph P Kopera and Nicholas, Brian and Todd, Dave and Davison, Jeff and Hanley, Tom and Kar, Aditya and La Tour, Timothy E. and Edwards, Tonya} } @proceedings {298, title = {Granite as a geothermal resource in the Northeast}, volume = {44}, year = {2012}, note = {Accession Number: 2012-090078; Conference Name: Geological Society of America, Northeastern Section, 47th annual meeting; Hartford, CT, United States; Conference Date: 20120318; Language: English; Coden: GAAPBC; Collation: 1; Collation: 76; Publication Types: Abstract Only; Serial; Conference document; Updated Code: 201247; Monograph Title: Geological Society of America, Northeastern Section, 47th annual meeting; Monograph Author(s): Anonymous; Reviewed Item: Analytic}, month = {2012/02/01/}, pages = {76 - 76}, publisher = {Geological Society of America (GSA) : Boulder, CO, United States}, address = {United States}, abstract = {In the absence of volcano-derived hydrothermal activity and high heat flow, granitic plutons provide an alternative geothermal resource from which heat may be usefully extracted. Compared with other crustal rocks, granites contain higher concentrations of the heat producing elements (K, U, Th). Additionally, they are more homogeneous and have simpler fracture systems than surrounding country rock, allowing for stimulation through hydro-fracking of large (>1 km (super 3) ) geothermal reservoirs. However, not all granites are created equal! Those with heat production > 5 mu W/m (super 3) , or with deep batholithic roots, are the most promising. Estimated temperatures at a given depth are related to the heat production, thickness and thermal conductivity of the granite. For example, the Carnmenellis Pluton in Cornwall, England (which will be drilled in 2012) is estimated to have temperatures in excess of 170 degrees C at a depth of 5 km, which is sufficient for co-production of electricity and hot water for heating. More importantly, granite bodies that are buried beneath thick sequences of thermally insulating sediments are also potential geothermal targets. Most successful examples to date include the Soultz sur Foret project in France, with temperatures of 200 degrees C at a depth of 5 km. (and which is currently producing electricity), Innamincka, Australia, with temperatures of 250 degrees C at a depth of 4 km. (which will be producing in 2012), and the seismically ill-fated project in Basel, Switzerland. Surely, if such projects involving the geothermal potential of granites, can succeed elsewhere, they can succeed here in the granite-rich Northeast? The geothermal potential of the Conway Granite, NH has long been recognized. Other possibilities include the Fitchburg Pluton, MA, and granites buried beneath the Carboniferous sediments of the Narragansett Basin and the Triassic sediments of the Connecticut River valley.}, keywords = {$\#$StaffPubs, Cammenallis Pluton, Cornwall England, Eastern U.S., Economic geology, geology of energy sources 29A, energy sources, England, Europe, geothermal energy, geothermal exploration, granites, Great Britain, heat flow, hydrothermal conditions, igneous rocks, intrusions, Northeastern U.S., plutonic rocks, plutons, thermal conductivity, United Kingdom, United States, Western Europe}, isbn = {00167592}, url = {https://gsa.confex.com/gsa/2012NE/finalprogram/abstract_200603.htm}, author = {John Michael Rhodes and Koteas, G.

The adoption of digital technology for geologic data collection, compilation, and distribution has many advantages but requires a similar shift in attitudes towards the nature of data and resulting maps themselves to ensure that they remain accessible, viable, and relevant in this new paradigm. We propose a set of guiding principles for the use of digital technology in geologic data and map production: 1.) Utilize dedicated digital data professionals (DDPs): It is unreasonable to expect that geologists maintain expertise in their field and be thoroughly versed in complex and rapidly changing best practices for digital data. Following the recommendations of the National Research Council (2009), DDPs should be embedded in any research endeavor from its inception with geologists being savvy enough in digital technology to maintain productive engagement with DDPs. 2.) Use appropriate technology: Fully digital workflows and field equipment are not appropriate for all projects. Free or open-source software (FOSS) and easily available low-cost hardware (i.e., smartphones) have also met or surpassed the utility of many proprietary technology solutions thus reducing the price and increasing accessibility of data. 3.) Practice good data management: Digital data takes considerable resources and sustained effort to remain viable even shortly after its production. Best practices in data accessibility (data standards, open formats, etc.) and maintenance (refreshing, migration, etc.) in addition to robust metadata creation, through all phases of a project, are unquestionably necessary. 4.) Approach maps and digital data as living dynamic entities: Geologic data is out of date the moment it is published. A primary advantage of digital datasets is their ability to be easily updated, queried, and manipulated in infinite ways. Derivative products for specific applications are in arguably higher demand by end users than the data itself. Geologists must design for flexibility, appropriateness of use, and the persistence of their expert interpretations through development of all possible end products of and updates to the map and dataset.}, keywords = {$\#$StaffPubs, data, data preservation, databases, digital, digital data, digital geologic maps, geologic maps, GIS, migration}, isbn = {00167592}, url = {https://gsa.confex.com/gsa/2014NE/webprogram/Paper236362.html}, author = {Joseph P Kopera and House, P.

Widely scattered terrestrial deposits of Cretaceous or Tertiary age and extensive nearshore and fluvial Coastal Plain deposits now largely beneath the sea indicate that the New England region has been above sea level during and since the Late Cretaceous. Estimates of rates of erosion based on sediment load in rivers and on volume of sediments in the Coastal Plain suggest that if the New England highlands had not been uplifted in the Miocene, the area would now be largely a lowland. If the estimated rates of erosion and uplift are of the right order of magnitude, then it is extremely unlikely that any part of the present landscape dates back before Miocene time. The only exception would be lowlands eroded in the early Mesozoic, later buried beneath Mesozoic and Cenozoic deposits, and exhumed by stream and glacial erosion during the later Cenozoic. Many of the rocks in the New England highlands are similar to those that underlie the Piedmont province in the central and southern Appalachians, where the relief over large areas is much less than in the highlands of New England. These comparisons suggest that the New England highlands have been upwarped in late Cenozoic time. The uplift took place in the Miocene and may have continued into the Quaternary. The New England landscape is primarily controlled by the underlying bedrock. Erosion and deposition during the Quaternary, related in large part to glaciation, have produced only minor changes in drainage and in topography. Shale and graywacke of Ordovician, Cambrian, and Proterozoic age forming the Taconic highlands, and akalic plutonic rocks of Mesozoic age are all highland makers. Sandstone and shale of Jurassic and Triassic age, similar rocks of Carboniferous age, and dolomite, limestone, and shale of Ordovician and Cambrian age commonly underlie lowlands. High-grade metapelites are more resistant than similar schists of low metamorphic grade and form the highest mountains in New England. Feldspathic rocks tend to form lowlands. Alkalic plutonic rocks of Mesozoic age underlie a large area in the White Mountains of New Hampshire and doubtless are a factor in their location and relief. Where the major streams flow across the regional structure of the bedrock, the location of the crossings probably is related to some other characteristic of the bedrock, such as joints or cross faults. The course of the Connecticut River is the result of the adjustment of the drainage to the bedrock geology during a long period of time. There is no ready explanation why many of the large rivers do not cross areas of calcalkalic plutonic rock, but rather take a longer course around such areas, which tend to include segments of the divide between the streams. The presence of coarse clastic materials in Miocene rocks of the emerged Coastal Plain of the Middle Atlantic States suggests uplift of the adjacent Piedmont and of the Adirondack Mountains at that time. The Miocene rocks of the submerged Coastal Plain in the Gulf of Maine and south of New England are fine grained and contain only small amounts of fluvial gravel. Perhaps the coarse clastic materials shed by the New England highlands in late Cenozoic time are buried by or incorporated in the Pleistocene glacial deposits.
