Stratabound pathways of preferred groundwater flow: An example from the Copper Ridge Dolomite in East Tennessee

The Copper Ridge Dolomite of the Upper Cambrian Knox Group underlies a site at Oak Ridge, Tennessee under consideration by the Department of Energy (DOE) for a below ground waste disposal facility. The Copper Ridge was studied for DOE to understand the influence of lithology on deep groundwater flow. Three facies types are distinguished which comprise laterally continuous, 1 to 4 m thick rock units interpreted to represent upward-shallowing depositional cycles having an apparently significant effect on groundwater flow at depth. Rock core observations indicate one of the recurring facies types is characterized by thin to medium-bedded, fine-grained dolostone with planar cryptalgal laminae and thin shaley partings. Distinctive fracturing in this facies type, that may have resulted from regional structural deformation, it considered to be responsible for weathering at depth and the development of stratabound pathways of preferred groundwater flow. In addition, geophysical data suggest that one occurrence of this weathered facies type coincides with an apparent geochemical interface at depth. Geophysical data also indicate the presence of several fluid invasion horizons, traceable outside the study area, which coincide with the unweathered occurrence of this fine-grained facies type. The subcropping of recurrent zones of preferred groundwater flow at the weathered/unweathered …

Use of polarimetry to measure the current profile in MTX (open access)

Use of polarimetry to measure the current profile in MTX

It is possible in principle to measure the poloidal magnetic field profile, and hence, the profile of the plasma current measuring the change in the polarization of a sequence of microwave beams that pass through the plasma. Actual measurements of the plasma current profile would be very interesting in connection with Lower-Hybrid (or EC) current drive experiments since this would provide direct information on modification of the current profile by the application of rf power. A microwave polarimetry diagnostic on MTX as part of the microwave interferometer is being considered. This diagnostic would be constructed in collaboration with Neville Luhmann and Tony Peebles at UCLA. The diagnostic would utilize the multicord far-infrared interferometer which is designed to operate at a base wavelength of 0.185 mm. This paper reviews the understanding of the physics issues raised by this diagnostic, concurring with Luhmann and Peebles' conclusion that the polarimetry measurements would be easier at longer wavelengths. An increase of only a factor of 2 in the wavelength would make a substantial difference since the signal to be measured goes as lambda/sup 4/. Hence, in this paper operation at longer wavelengths (0.337 mm and 0.447 mm) in addition to operation at 0.119 and …

Bank Failures: Recent Trends and Policy Options (open access)

Bank Failures: Recent Trends and Policy Options

During the 1980s the U.S. banking industry has experienced a rapidly growing number of failures. Many factors have contributed to this trend including deregulation, technology, individual bank management, and economic conditions. The Federal Deposit Insurance Corporation (FDIC) handles insured bank failures. Congress has been monitoring the recent trend and is concerned with the FDIC’s ability to continue to perform its supervisory and insurance operations. The present situation, information on key factors affecting the banking industry, and the FDIC’s role when a bank fails is discussed in this report. The reference section of this issue brief contains a list of CRS products providing background on the FDIC and legislative issues relevant to the agency.

Texas Register, Volume 12, Number 53, Pages 2273-2316, July 14, 1987

A weekly publication, the Texas Register serves as the journal of state agency rulemaking for Texas. Information published in the Texas Register includes proposed, adopted, withdrawn and emergency rule actions, notices of state agency review of agency rules, governor's appointments, attorney general opinions, and miscellaneous documents such as requests for proposals. After adoption, these rulemaking actions are codified into the Texas Administrative Code.
