Introduction to STARPAC: the Standards Time Series and Regression Package

Description: From preface: STARPAC documentation is being published as a series of Technical Notes. This Note is the first in the series. It gives an overview of the STARPAC library, defines conventions used in the documentation, provides an example using STARPAC subroutines, and presents general background material. This Note includes information which is essential for using the STARPAC library, and users should be familiar with its contents before attempting to use any STARPAC subroutine.

Nonlinear Least Squares Regression Using STARPAC: The Standards Time Series and Regression Package

Description: From preface: This Note documents 16 subroutines for nonlinear least squares regression. Twelve of these compute the least squares estimates, performing either weighted or unweighted analysis with either numerically approximated or user-supplied (analytic) derivatives. The other four are user-callable subroutines for two procedures used within the estimation code: the first selects optimum step sizes for approximating the partial derivatives of the model; and the second checks the validity of a user-supplied derivative subroutine.

Reference Flat Pulse Generator

Description: Introduction: A reference step-like pulse generator is described which has been developed at NBS. This generator can be used for accurately characterizing the step response of various kinds of trap ient recording equipment (oscilloscopes, waveform recorders, transient digitizers, etc.). Basic design principles are given as well as complete circuit diagrams and descriptions. An analysis of the output stage of the generator is presented together with the circuit models for developing a time-domain computer simulation program using extended- SCEPTRE. Preliminary specifications indicate that the NBS Reference Flat Pulse Generator provides a negative-going reference transition duration (90 to 10 percent) of 600 ps, *20 percent with baseline perturbations of less than *2 percent for less than 5 ns.

National Uranium Resource Evaluation: Data Release on the Salton Sea Quadrangle, California and Arizona

Description: From objectives: In the Salton Sea Quadrangle, reported uranium occurrences were evaluated, and geologic environments thought to be favorable were examined. This report includes the field data collected during that work and a summary of the quadrangle geology and uranium favorability. This is the final report to be prepared on this quadrangle under the NURE program.

Reports on Investigations of Uranium Anomalies

Description: Introduction: The Hylas Zone, a northeast-trending belt of mylonite and ultramylonite, lies in the eastern Piedmont Province of Virginia and borders the northern end of the Richmond Basin (Fig. I-1). The north-trending Richmond Basin is 58 km long and a maximum of 16 km wide. Early indications of anomalous uranium concentrations in the region came from discussions with Jan Krason, GeoExplorers International, Denver, who had worked in the area. Examination of aerial radiometric data (Geodata International, 1975) and HSSR data (Cook, 1981) indicated anomalous values of uranium in the area northwest of Richmond. During June 1981, a 5-day trip to the Hylas area was undertaken to collect rock and ground-water samples and to identify possible source and host rocks of uranium.

Geologic Study of Kettle Dome, Northeast Washington: Final Report

Description: From abstract: This geologic study of Kettle dome, northeast Washington, encompasses an area of approximately 800 square miles (2048 sq km). The evaluation of uranium occurrences associated with the igneous and metamorphic rocks of the dome and the determination of the relationship between uranium mineralization and stratigraphic, structural, and metamorphic features of the dome are the principal objectives. Evaluation of the validity of a gneiss dome model is a specific objective. The principal sources of data are detailed geologic mapping, surface radiometric surveys, and chemical analyses of rock samples.

Review of Potential Host Rocks for Radioactive Waste Disposal in the Southeast United States, Southern Piedmont Subregion

Description: From abstract: "A literature study was conducted on the geology of the Southern Piedmont province of the states of Maryland, Virginia, North Carolina, South Carolina, and Georgia. The purpose was to identify geologic areas potentially suitable for containment of a repository for the long-term isolation of solidified radioactive waste."

Uranium in Granites From the Southwestern United States: Actinide Parent-Daughter Systems, Sites and Mobilization: First Year Report

Description: From summary: In this first annual report for subcontract BFEC 79-384-E (Uranium in Granites of Southwestern North America) we have established the general geological and geochemical background for our investigations. We describe the regional setting and some important geochemical patterns, constituting a major uranium anomaly, of the Precambrian basement in the Colorado Plateau region. Three of our investigated samples were derived from a portion of this region in central and northern Arizona. We describe the tectonic and petrologic setting for a fourth sample, a granite from the young (Cretaceous) Peninsular Ranges Batholith of southern California.

Preliminary Study of the Uranium Potential of the Dan River Triassic Basin System, North Carolina and Virginia

Description: From summary: A preliminary geologic investigation was conducted to determine the uranium potential of the Triassic strata in the Dan River basin system (Dan River, Danville, and Davie County Triassic basins) of North Carolina and Virginia. The pre-Triassic Inner Piedmont basement rocks adjacent to the basins were investigated as potential sources of uranium. Outcrops of Triassic and basement rocks were examined and measured for surface radioactivity by scintillometer. Representative rock and saprolite samples were collected for laboratory analyses.
