A report regarding an airborne gamma-ray spectrometer and magnetometer survey of the Brainerd Quadrangle, Minnesota

Appendices containing data on uranium availability in the Eau Claire Quadrangle to accompany a report on U.S. uranium resources in Wisconsin and Minnesota.

From Purpose and Objectives: This study was made primarily to provide a means to depict and forecast stream quality based on known causative or apparent correlative factors.

From abstract: This report presents data collected from four lakes in Lakeville, Minnesota to determine water-quality characteristics and evaluate "changes that may occur in the lakes because of urbanization." It contains a map, graphs, tables, and a glossary.

Purpose and scope: The Eau Claire Quadrangle, Wisconsin and Minnesota, was evaluated to identify geologic units and delineate areas that exhibit characteristics favorable for the occurrence of uranium deposits. All geologic environments to a depth of 1500 m (5,000 ft) were evaluated by means of surface investigations and available subsurface data. Each environment was categorized as favorable, unfavorable, or unevaluated for uranium deposits based on recognition criteria contained in the study of significant uranium districts worldwide (Mickle and Mathews, eds., 1978). Evaluation of the Eau Claire Quadrangle was conducted by Golder Associates, Inc., under subcontract to Bendix Field Engineering Corporation (BFEC), for the National Uranium Resource Evaluation (NURE) program, managed by the Grand Junction Office of the U.S. Department of Energy (DOE). The evaluation program began February 1, 1978, and ended February 1, 1980. Time spent by Golder personnel on literature search, field work, evaluation of data, and preparation of the final report totaled approximately 3.5 man-years.

Abstract: Seven test holes drilled in the Glacial Lake Agassiz Peatlands indicate that the thickness of surficial materials along a north-south traverse parallel to Minnesota Highway 71 ranges from 163 feet near Blackduck, Minnesota to 57 feet about 3 miles south of Upper Red Lake. Lenses of sand and gravel occur immediately above bedrock on the Itasca moraine and are interbedded with lake clay and till under the peatlands. Vertical head gradients measured in a piezometer nest near Blackduck on the moraine are downward, indicative of recharge to the regional ground-water-flow system. Vertical head gradients are upward in a piezometer nest on a sand beach ridge in the peatlands 12 miles north of Upper Red Lake. Numerical sectional models indicate that this discharge probably comes from local flow systems recharge from ground-water mounds located under large raised bogs.

A report regarding evaluations done of the Ashland Quadrangle to find favorability for uranium occurrences in the quadrangles geologic environments. "No favorable areas could be identified or delineated on the basis of available data, and it is concluded that geologic environments in the Ashland Quadrangle are unfavorable for uranium."

Report discussing lake-bottom sediment sampling; radon soil gas surveying, and chemical analyses for rock, stream-sediment, ground, spring-water, lake-water, and stream-water samples collected for a report discussing the favorability for uranium occurrences in geologic environments of the Ashland quadrangle of Wisconsin, Michigan, and Minnesota.
