The preferred mode of access to both an intermediate (~1560 m) and deep campus (~2300 m) is via a straight decline with a secondary access/egress via shaft (Appendix I). The underground laboratories and access tunnels will be developed in massive, high strength, Paleozoic limestones and dolostones (Appendix B). Abundant exposures show these rock units to be highly competent (UCS ~100-150 MPa), with major fractures occurring in well-defined sets with spacings on the order of several hundred meters. Prominent blocks of massive carbonate rock characterize the landscape - for example the “Palisades” along the New River at Pembroke. The shallowly-dipping stratigraphy and gently-incised topography allows a linear decline to remain primarily within anticipated competent high strength limestones. Possible short excursions into adjacent competent mudstones and slates within the Martinsburg Formation are unlikely to be squeezing (above ~1400-2700 m) and such deviations are expected to be short if they occur at all. Fracture data from surface and underground (mine) locations confirm the anticipated competence of the limestone formations that will potentially host large caverns. Rock mass classification by Q and RMR methods uniformly identify the rock mass as ”good” - the second most favorable of five categories. This classification suggests that access tunnels (assumed ~4.5 m diameter) will require either no support or only spot bolting. This is consistent with existing tunnels of similar span mined to a depth of 750 m. Similarly, these “good quality” massive limestones will successfully accommodate large- span (40-60 m) UNO-type caverns. Projected support requirements for a 50 m span cavern in “good” rock (Q~20) are systematic bolting and shotcrete. Such rocks are documented to routinely host large cavities underground, and this is confirmed by large cavities (10×30×500 m) present to 750 m depth. The feasibility of constructing large underground openings at Kimballton is demonstrated by large chambers in the Kimballton mine that have stood completely unsupported for 40 years or more. The mine at Kimballton is developed in the Five Oaks limestone, a subunit of the Middle Ordovician limestone that will host access tunnels and underground laboratories at depth. Rather than having a separate section presenting geomechanical data and experience from the mine, this information is included wherever the particular topic is discussed (e.g., fracturing, water, stability). The management of uncertainty and risk, and the mechanisms by which information from the S-2 phase will be used to reduce risk are detailed in Appendix B - Geologic Setting, and in Appendix H – Risk and Uncertainty. 2 Major characteristics that indicate favorable conditions for constructing DUSEL, including large caverns at a depth of 2300 m, at Kimballton include the following. 1. Very large underground openings in the Kimballton mine, with heights up to 34 m, lengths up to 500 m and width of 14 m, have been stable for decades without support, or with occasional rockbolts in areas of heavy usage (e.g., lunch areas). These caverns are at depths up to 750 m, indicating competent rock and no major stress problems. 2. The formations to be encountered at depth are generally massive rocks, with widely spaced parallel fractures. Tunnels and underground chambers can be aligned between major fractures (if they persist at depth) to minimize stability problems. 3. The proposed host rocks for the Kimballton-DUSEL - the Knox and Middle Ordovician carbonates – are high strength rocks (UCS~100-150MPa). 4. Q values from area quarries and outcrops indicate “Fair” to “Very Good” rock quality. Most of the data indicate “Good” quality. Rock Mass Rating (RMR) values from area quarries and outcrops consistently indicate “Good” rock quality. These rock mass classification values are likely to be inferior to values at depth, due to near- surface stress relief and weathering. 5. Seismic data also indicate no degradation in rock quality with depth. Q-values from seismic velocity indicate “Good” to “Very Good” rock quality. No major differences in field and laboratory measured seismic velocities confirm the massive character of the rocks, and the absence of open fractures at depth. 6. The sedimentary rocks at Kimballton are particularly well suited to TBM (tunnel boring machine) tunneling – as they are high strength, but not abrasive. Potential difficult areas can be excavated using drill and blast methods. 7. Good stability numbers indicate no potential problems from squeezing and rock bursting. 8. No major water inflows occur in the existing Kimballton mine (which has close to 100 km of drifts), except at one location. Localized areas of water inflow can be pre- grouted before excavation. Fracture frequency typically decreases with depth, and due to insitu stresses fractures that do occur are unlikely to be open (e.g., Cosgrove and Engelder, 2004) 9. The geometry of existing caverns (tall and narrow) indicates an absence of high horizontal stress (in comparison to vertical stress). 1.1 Authorship This Appendix was prepared by the Kimballton Team at Virginia Tech. Contributions and reviews were received from H. H. Einstein, D. Elsworth, A. Bobet and L. Gertsch. 3 2 Introduction This preliminary report describes geotechnical conditions for the proposed national Deep Underground Science & Engineering Laboratory (DUSEL) under Butt Mountain at Kimballton VA. (referred to as Kimballton-DUSEL in this report). Kimballton-DUSEL is adjacent to an existing limestone mine, the Kimballton mine, which is owned and operated by Chemical Lime Company. Kimballton-DUSEL will be developed at depth primarily in massive limestones and dolostones. These same formations outcrop in quarries and road cuts in the vicinity of Butt Mountain (Fig. 2-1). As part of the preliminary assessment of geotechnical conditions for the underground lab, fracture data and rock samples were collected at these quarries and road cuts, with limited geomechanical data collected from within the Kimballton mine. In addition we report strength data on core samples collected in 1990 by Chemical Lime. Presented in this appendix are (1) an overview of the geologic setting; (2) geomechanical data for the

  • Stratigraphy, Structure, and Tectonics: an East-To-West Transect of the Blue Ridge and Valley and Ridge Provinces of Northern Virginia and West Virginia
    FLD016-05 2nd pgs page 103 The Geological Society of America Field Guide 16 2010 Stratigraphy, structure, and tectonics: An east-to-west transect of the Blue Ridge and Valley and Ridge provinces of northern Virginia and West Virginia Lynn S. Fichter Steven J. Whitmeyer Department of Geology and Environmental Science, James Madison University, 800 S. Main Street, Harrisonburg, Virginia 22807, USA Christopher M. Bailey Department of Geology, College of William & Mary, Williamsburg, Virginia, USA William Burton U.S. Geological Survey, Reston, Virginia 22092, USA ABSTRACT This fi eld guide covers a two-day east-to-west transect of the Blue Ridge and Valley and Ridge provinces of northwestern Virginia and eastern West Virginia, in the context of an integrated approach to teaching stratigraphy, structural analysis, and regional tectonics. Holistic, systems-based approaches to these topics incorpo- rate both deductive (stratigraphic, structural, and tectonic theoretical models) and inductive (fi eld observations and data collection) perspectives. Discussions of these pedagogic approaches are integral to this fi eld trip. Day 1 of the fi eld trip focuses on Mesoproterozoic granitoid basement (associated with the Grenville orogeny) and overlying Neoproterozoic to Early Cambrian cover rocks (Iapetan rifting) of the greater Blue Ridge province. These units collectively form a basement-cored anticlinorium that was thrust over Paleozoic strata of the Val- ley and Ridge province during Alleghanian contractional tectonics. Day 2 traverses a foreland thrust belt that consists of Cambrian to Ordovician carbonates (Iapetan divergent continental margin), Middle to Upper Ordovician immature clastics (asso- ciated with the Taconic orogeny), Silurian to Lower Devonian quartz arenites and car- bonates (inter-orogenic tectonic calm), and Upper Devonian to Lower Mississippian clastic rocks (associated with the Acadian orogeny).

  • Application of Foreland Basin Detrital-Zircon Geochronology to the Reconstruction of the Southern and Central Appalachian Orogen
    JG vol. 118, no. 1 2010 Tuesday Oct 27 2009 01:03 PM/80097/MILLERD CHECKED Application of Foreland Basin Detrital-Zircon Geochronology to the Reconstruction of the Southern and Central Appalachian Orogen Hyunmee Park, David L. Barbeau Jr., Alan Rickenbaker, Denise Bachmann-Krug, and George Gehrels1 Department of Earth and Ocean Sciences, University of South Carolina, Columbia, South Carolina 29208, U.S.A. (e-mail: [email protected]) ABSTRACT q1 We report the U-Pb age distribution of detrital zircons collected from central and southern Appalachian foreland basin strata, which record changes of sediment provenance in response to the different phases of the Appalachian orogeny. Taconic clastic wedges have predominantly ∼1080–1180- and ∼1300–1500-Ma zircons, whereas Acadian clastic wedges contain abundant Paleozoic zircons and minor populations of 550–700- and 1900–2200-Ma zircons q2 consistent with a Gondwanan affinity. Alleghanian clastic wedges contain large populations of ∼980–1080-Ma, ∼2700- Ma, and older Archean zircons and fewer Paleozoic zircons than occur in the Acadian clastic wedges. The abundance of Paleozoic detrital zircons in Acadian clastic wedges indicates that the Acadian hinterland consisted of recycled material and possible exposure of Taconic-aged plutons, which provided significant detritus to the Acadian foreland basin. The appearance of Pan-African/Brasiliano- and Eburnean/Trans-Amazonian-aged zircons in Acadian clastic wedges suggests a Devonian accretion of the Carolina terrane. In contrast, the relative decrease in abundance of Paleozoic detrital zircons coupled with an increase of Archean and Grenville zircons in Alleghanian clastic wedges indicates the development of an orogenic hinterland consisting of deformed passive margin strata and Grenville basement.

Anderson, Professor Emeritus, Faculty ii Copyright © by Mary K. McGuire 2012 iii DISTRIBUTION OF COGENETIC IRON AND CLAY DEPOSITS IN THE CENTRAL APPALACHIAN REGION Mary K. McGuire, M.S. University of Pittsburgh, 2012 Maps of more than 500 abandoned iron mines, 350 early iron furnaces, and numerous clay mines in the central part of the Appalachian region reveal the distribution and close association of siderite-limonite bearing ores and clay deposits. The deposits crop out from Lancaster County, Pennsylvania to Scioto County, Ohio, a distance of more than 300 miles. The geologic settings of the deposits are diverse. In the Valley and Ridge Province and Piedmont Province, mineralization follows structures such as major sub-horizontal thrust faults (e.g. Martic) and steep thrust faults, (e. g. Path Valley), that juxtapose carbonate units against other rocks. Carbonate units within the Plateau Province also contain economic deposits of iron ores and clay. The ores are commonly siderite and limonite principally in the form of nodules and other irregular masses in clayey, calcareous beds.

  • GPFA-AB Reservoirs Data Appendix Erin
    GPFA-AB Reservoirs Data Appendix Erin Camp Last modified: August 31, 2016 This memo is intended to augment the Natural Reservoirs Methodology memo, by providing additional details about the original databases and modified inputs for the Appalachian Basin Geothermal Play Fairway Analysis project. All research and literature that affected decisions for the reservoir data inputs are recorded here, including data for geologic formations in the Appalachian Basin. DATABASE INTEGRATION Two disparate databases were integrated for this project: 1) the Empire State Organized Geologic Information System (ESOGIS; data for reservoirs in New York), and 2) the Midwest Regional Carbon Sequestration Partnership (MRCSP; data for reservoirs in Pennsylvania and West Virginia). When the two databases were merged, there were discrepancies between the available data and the terminology used in each database. 1. Geologic Formation Name: The following formation codes were listed in the MRCSP database. The decrypted formation name for each is listed next to the code. Very often, the name of a formation in Pennsylvania and West Virginia is different than the given name of the same formation in New York. For those formations, the New York formation name was used. If a reservoir is listed as having produced from a smaller unit within a larger formation, the formation name was used. Any formation name changes are listed in parentheses next to the original formation name, shown below. a. BLDG: Bald Eagle b. BILDF: Bass Islands Formation c. BKMN: Beekmantown d. BNSN: Benson e.
