Earth resistivity as a tool for shallow exploration in the Reelfoot Lake area, Tennessee. [Location of old river channels, faults]
Technical Report
·
OSTI ID:5235620
Surface earth resistivity techniques were successfully tested at a shallow (10's of feet) depth in the Reelfoot Lake area of Mississippi alluvial plain. Profiling, Barnes Layer sections, Wenner soundings, and circle soundings proved useful. Features of abandoned river channels (a central low resistivity clay plug and lateral high resistivity, sandy natural levees) were readily located and mapped by profiling. Faults were located within about 50 feet by profiling and Barnes Layer profiling, and were located within 10 feet or less by circle soundings. Approximately true resistivity columns were made by measuring the resistivity of samples from small diameter holes. For these columns, Wenner Array soundings gave nearly correct layer thickness estimates in contrast to erroneous Schlumberger soundings.
