Aerial gamma ray and magnetic survey: Minnesota Project, Escanaba quadrangle of Michigan and Wisconsin. Final report. [No known uranium deposits within the study area]

Technical Report · Fri Feb 01 00:00:00 EST 1980

OSTI ID:5602508

The Escanaba 1/sup 0/ x 2/sup 0/ scale quadrangle of northern Michigan and northeastern Wisconsin is almost completely covered with Wisconsinan glacial deposits (moraines, outwash, lake deposits, etc.) of variable thickness. Where exposed, bedrock is of Precambrian and Early to Middle Paleozoic age. Precambrian age bedrock is primarily igneous and metamorphic, whereas the Paleozoic sequence consists almost entirely of limestone and dolomite. There are no uranium deposits known within the study area, though the Elliot Lake quartz pebble conglomerate uranium deposit lies northeast in the Canadian portion of the Blind River quadrangle. Magnetic data illustrate relative depth to magnetic basement in the area. Sources appear to be shallow over most of the land surface. Twenty-three groups of uranium samples were defined as anomalies and discussed briefly in this report. None of them are considered significant.
