Title:
Active and potentially active faults in or near the Alaska Highway corridor, Dot Lake to Tetlin Junction, Alaska
Abstract:
In 2005, the Alaska Division of Geological & Geophysical Surveys initiated a multi-year geologic field study focused on a corridor centered along the Alaska Highway between Delta Junction and the Canada border. The purpose of this project is to provide geologic information relevant to a proposed Alaska-Canada natural gas pipeline and other future development in the corridor. The scope of this project includes identification of active faults and characterization of seismic hazards. During the 2008 field season the active fault studies were focused on the central part of the corridor between Dot Lake and Tetlin Junction. Field studies included helicopter and fixed-wing air reconnaissance augmented by interpretation of stereo air photos, remotely sensed images, ground reconnaissance, and field mapping. Detailed investigations were conducted where the reconnaissance identified lineaments indicative of Holocene surface faulting. In addition, detailed field studies were conducted of several lineaments identified in the published literature as possible active faults. The detailed studies included field mapping, topographic profiling, trenching, and 14C dating of surficial sediments associated with lineaments exhibiting characteristics of active faults. Two faults and a large fault-related anticline were found to have generated late Pleistocene and Holocene surface deformation in the Dot Lake-Tetlin Junction section of the corridor. These structures, the eastern part of the Dot "T" Johnson fault, the Cathedral Rapids fault, and the Giant Moletrack anticline, are active structures in the eastern part of the NFFTB. Detailed investigation of the Mansfield and Dennison Fork lineaments, identified as candidate active faults in the literature, produced conclusive evidence that they are not active faults. Detailed study of a third suspect lineament, the Bear Creek lineament, was inconclusive.

  2. How were the data generated, processed, and modified?

    Date: 2008 (process 1 of 5)
    Initial reconnaissance - an initial interpretation of stereo air photos, remote sensed images, DEMs, and topographic maps of the corridor and surrounding regions was done prior to fieldwork. We also conducted a review of published and unpublished reports and geologic and geophysical survey maps to identify and locate lineaments and potentially active faults for further study. This initial phase was followed by helicopter reconnaissance of the corridor and adjacent regions with emphasis on potential faults and lineaments identified from the review of literature, air photos, remote sensed images, and maps. Based on the initial studies and the air reconnaissance, we identified lineaments and potentially active faults judged to warrant further studied in the field and selected sites for detailed investigation.

    Date: 2008 (process 2 of 5)
    Fieldwork - In July-August 2008, to further study specific sites identified in preliminary reconnaissance. The detailed investigations included geologic and geomorphic mapping, scarp profiling, measurement of scarp height and fault offset, and at selected sites, trenching and coring to develop paleoseismic information for active fault characterization

    Date: 2008 (process 3 of 5)
    Trenching - Trench sites were chosen to transect features suspected to be active faults, in order to expose a cross sectional view of faults and the most recent stratigraphy. At sites that were inaccessible to motorized excavation equipment we hand-dug the trenches. To facilitate field interpretation and logging we used nails to pin colored flagging along exposed contacts and faults on the cleaned trench walls. Logging of the trench walls was done by placing a grid of horizontal and vertical string lines over the exposed trench wall, and used this grid to accurately measure and transfer each feature to cross section Mylar. Each stratigraphic layer and feature of interest was described and locations of radiocarbon samples were recorded. Soil and sediment colors for each stratigraphic unit were defined using a Munsell Soil Color chart. Where possible, we collected radiocarbon samples from layers bounding faulting events to bracket the age of paleo-earthquakes interpreted from the stratigraphy. Upon completion, we backfilled the trenches, re-contoured the trench sites and replaced the natural vegetation.

    Date: 2008 (process 4 of 5)
    Labwork - The radiocarbon samples were carefully extracted to minimize contamination. Samples were stored in the field in aluminum foil bundles which were placed in labeled plastic bags after air-drying, and the dry samples transferred to labeled glass vials once they were out of the field. Before being sent to the laboratory for analyses, each sample was inspected through a binocular microscope, picked clean of mineral debris, and for some samples, individual plant macrofossils or charcoal grains were separated for analysis. Beta Analytic Radiocarbon Dating Laboratory in Miami Florida performed the radiocarbon age analyses on the 14C samples.

    Date: 2010 (process 5 of 5)
    Metadata creation - Metadata were assembled by T.D. Hubbard, G.C. Carver and R.A. Westbrook FGDC Standards using Metavist 1.2, DGGS 7.05, a data entry program for FGDC metadata with XML output.

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?

    Locations of trenches, core sites and profiles are given for the approximate mid-point of each feature. The radiocarbon samples were carefully extracted from trench walls and cores to minimize contamination. Samples were stored in the field in aluminum foil packets which were placed in labeled plastic bags after air-drying, and the dry samples transferred to labeled glass vials once they were out of the field. Before being sent to the laboratory for analyses, each sample was inspected through a binocular microscope, picked clean of mineral debris, and for some samples, individual plant macrofossils or charcoal grains were separated for analysis. Beta Analytic Radiocarbon Dating Laboratory in Miami Florida performed the radiocarbon age analyses on the 14C samples. Samples were pretreated using the acid/alkali/acid standard pretreatment protocol. All analysis was done using AMS methods and included 13C corrections. Quoted errors for laboratory ages represent 1 standard deviation statistics (68% probability) and are based on combined measurements of the sample, background, and modern reference standards. Measured 13C/12C ratios were calculated relative to the PDB-1 international standard and the radiocarbon years before present ("Lab Age") were normalized to -25 per mil.

    Laboratory ages were then calibrated using the OxCal v4.0 calibration program and the IntCal 04 calibration curve. All calibrated ages are reported as calibrated 2 sigma ranges before present (cal BP). The data in Appendix 1 report the method used, material type, paleoseismic significance, sample and lab numbers, lab age, 13C/12C ratios, and two-sigma calendar calibration result for each of the 20 radiocarbon samples. References for the calibration methods, as reported by Beta Analytic Inc. are: Stuiver, M., and van der Plicht, H., Radiocarbon, 1998, vol. 40, no. 3, p. xii-xiii. Stuiver, M. and others, Radiocarbon, 1998, vol. 40, no. 3, p. 1041-1083. Talma, A.S. and Vogel, J.C., Radiocarbon, 1993, vol. 35, no. 2, p. 317-322.

  2. How accurate are the geographic locations?

    Locations of points recorded in the table were recorded using a Garmin GPS model 76CSx with a horizontal error of 4 meters or less. The locations are for approximate mid-point of each trench. Individual radiocarbon age samples in Appendix 1 are referred to their respective trenches and core sites whose locations are listed in Table 1. The spreadsheet distribution file is a compilation of Table 1 and Appendix 1. The actual location of each radiocarbon sample within the trench or core is shown in the trench logs and core logs in the figures of this report. Locations shown on the logs were determined using a metric tape, measuring distances from defined origins, to half-centimeter accuracy.

  3. How accurate are the heights or depths?

  4. Where are the gaps in the data? What is missing?

    All of the samples collected for dating were submitted for analysis and presented in this report.

  5. How consistent are the relationships among the observations, including topology?
